Abstract

This work draw on quantum mechanics, multiverse theory, and posthumanist thought to

discuss how quantum posthumanism reconceptualizes identity, agencies and temporality. It all

relates to me from the angle of quantum theory, emphasizing probabilistic states, interaction and

so-called many-worlds interacting in the moment. Quantum entanglement, superposition,

nonlinear temporality, these ideas undermine notions of the singular, self-contained individual.

Riddled with choices and spending perhaps infinite lives pursuing their own interests, ethical

dilemmas frequently arise when considering versions of oneself; which individual deserves

moral accountability in given situations, and to what extent does that conflict with human

perspectives of free will? That complexity is illustrated in speculative fiction, in which

characters’ choices echo through alternative histories. With the integration of artificial

intelligence, virtual reality, and quantum computing, posthuman identity blurs identity between

human and machine, self and environment. AI systems generate meanings through relational

processes, and such meanings are placed within a sequence of events vs humans experience

fragmented virtual realities and identities in VR. Quantum computing mirrors our posthuman

reality, where outcomes rely on observation at least as much as intention. There are potential

implications here for the study of multiversal subjectivity, which will only proliferate in cultural

texts as discussed in this panel, and emergent discourse through narrative structures on identity,

agency, and the potential inscribing(s) of engagement. However, as technology deepens the

divide between the body and the mind, the clash of the fears seen in recent sciences will

inevitably force (this) at the expense of the (human) linked world to the world beyond (the

body).

Introduction: Defining Quantum Posthumanism

Quantum posthumanism is therefore a fusion of quantum mechanics with posthumanist

theorisation, creating new ideas about identity and agency. According to Hicks (2022), this

perspective also complicates anthropocentric ontology by aligning tenets of entanglement,

superposition, and nonlinear temporality with models of selfhood. It raises questions about how

fragile identity is in a mind that spills across diverse realities rather than a single linear

chronology. As Hicks (2022) points out, posthumanism breaks the empathic boundaries of

traditional humanist narratives by stretching agency beyond the human body, with technology

and nonhuman entities equally involved in a person becoming who they are. This alters the way

selfhood is conceptualized, particularly in speculative fiction and multiversal narratives. It means

human existence has transcended the limitations of biology itself and merged into the vibrant

and intertwined tapestry of possibilities that is our world. It is the application of quantum theory

that obfuscates the distinction between self and other. That stems from a process called quantum

superposition, which means that as an identity, you can exist in multiple states, in a way, until a

node in the network forces the identity somewhere through an act of observation. This rings a

bell in the realm of digital identities, as people shape various avatars in virtual worlds. Nonlinear

temporality suggests that time is not experienced in a linear sequence but rather experienced in

overlapping recursive loops. Like, this fundamentally changes how you think about memory,

presence, and agency in a multiverse context. Thus, we can no longer see a traditional vision of

a united and one self; according to quantum posthumanists, a self, even a continuous one, cannot

exist as something “one” or “whole” in principle. This vision is amplified by the growing

convergence of technology and human thought, demonstrating that both in the real world and in

cyberspace, identity is not a solid state but a permeable, fragmented process.

Posthumanist thought arises at the intersection of technoscience and ontology, and it

undermines anthropocentrism by positing intelligence, agency, and identity to be emergent

properties of complex networks, not the defining properties of autonomous human subjects.

Transhumanism, which aims to enhance the human condition through technological

augmentation, stands at odds with posthumanism, which dismantles human exceptionalism by

embedding cognition and subjectivity in the wider web of intra-action among human, nonhuman,

and nonliving things (Fuller, 2017; Rugo, 2020). This view upends fixed notions of selfhood,

pointing out that intelligence is distributed, emerging through relational entanglements with the

environment. The quantum mechanics take this discourse further by positing that identity is not

constant but dependent upon observation, where wave-function collapse asserts that reality itself

is created through action of measurement. This new probabilistic frame frustrates determinative

notions of subjectivity within models of selfhood that are always subject to change depending on

context. These concepts affect not just philosophy, but also discourse about artificial

intelligence, digital identities, and computational ethics. So, AI and synthetic autonomy are

redefining the nature of that boundary at the very level of cognition, for which a quantum

posthumanism provides a necessary reconstruction of ethical implications going forward. In a

posthuman future where the line between the organic and synthetic cognition fuzzy quantum

computing will add a new dimension of complexity to previous epistemological models that

distill knowledge, perception and existence itself.

Quantum posthumanism not only grapples with implications towards identity building,

but also speculates on temporal frameworks between these two paradigms. Posthumanist theories

thus dismiss linear false temporalities in favor of dynamic, relational, and recursive temporal

structures. Posthumanism reframes temporalities by abandoning the linear and the progressive

as guiding principles in favor of cyclical (Crellin and Harris, 2021; p. 32) and emergent (p. 88)

qualities of time. These ideas resonate with quantum mechanics, where time does not flow

uniformly but is a probabilistic dimension dependent on observation. Disrupted time in

multiversal narratives portrayed through identity as existing in multiple timelines to make claim

to agency and self-determination. Can (2023) extends this perspective by describing how digital

technologies facilitate posthuman identities through fragmented, nonlinear experiences of

reality. This aligns with Barad’s (2007) theory of agential realism, that is, the idea that reality is

not something that exists antecedent to the world, but rather is produced through the interaction

of entities. The disintegration of the fixed temporal structures imply that the concept of identity

should not be interpreted as something “to be” but as transitive, contingent, iterated, the result of

intra-actions, liminal not just personal but also cultural. Because of this, the idea that selfhood is

a stable construct is challenged, rather suggesting that it is a fluid web of entanglements

influenced by human and nonhuman matter. What do the implications of this temporal shift

mean not only for philosophy but for artificial intelligence, virtual reality and digital storytelling?

Quantum posthumanism does not offer fixed ontological conditions, but rather an ontology

temporally contingent on the outcomes of various affective relations, guided by entropy rather

than linearity.

Theoretical Foundations

Quantum Entanglement and Nonlinear Temporality

The fluid, interactive nature of time then becomes evident through quantum mechanics,

shattering the barriers that are standard ideas of time. Classical physics views time linearly,

whereas quantum theory suggests time is dynamic and observant-dependent. Barad (2017)

suggests that time is less a frame for events to take place in and more a co-actor in the process of

reality’s becoming. This idea corresponds with Bohm’s implicate order, which suggests all

moments in time are enfolded into each other, coexisting in a continuous and inter-related

pattern. During interactions, it has been determined that entangled particles are influenced by

one another regardless of distance, leading Erhard, Krenn, and Zeilinger (2020) to investigate the

implications of this phenomenon for our understanding of time, as well. These perspectives make

traditional notions of causality more complex, which imply an interaction of past, present and

future that illogically takes place in a linear time order. The implications here reach beyond

theoretical physics, into a posthuman identity, where selfhood is equally fluid. In multiversal

stories, consciousness is no longer locked to one timeline, but instead exists probabilistically

across multiple realities. Consequently, this disrupts our traditional ways of thinking about

agency, in which both agency and the self are seen to merge in a flickering instant.

The relationship undermines classical notions of distance and identity and shows that

entangled particles affect one another, even at a distance. Indicating that the source of truth does

not exist in the stringent borders of Cartesian separation. The question of how legal

entanglement should be categorized–as either a quantum effect or a behavior shared with

classical systems–is taken up in the work of Paneru, Cohen, Fickler, Boyd, & Karimi (2020).

Their findings affirm the perspective that quantum entangled states hold distinctive qualities,

especially considering their nonlocal connectedness. Following up on this work, Schlawin,

Dorfman, and Mukamel (2018) adopt an even more detailed focus on entangled photon

absorption, noting how information is transmitted in ways that cannot be characterized or

understood in traditional spatial terms. One posthuman theory that resonates with this

interconnectedness is that identity is not singular but rather distributed and contingent. In many

fictional representations, however, characters in multiversal narratives endure separate selves

that carry on, having multiplied across timelines. Their consciousness is not individual but

shared among entangled iterations of them, questioning agency. If the self exists in multiple

iterations at once, then the ethical implications of that multiplicity are that responsibility and

consequence are no longer limited to one reality.

Under quantum mechanics, a particle exists in every possible state until it is observed, at

which point it collapses into a specific state. Schlawin et al. (2018) explores this principle in the

context of the absorption of entangled photons, shedding light on its consequences for the

fundamental understanding of matter. The investigations by Zhang, Scully and Agarwal (2019)

are extending this point by exploring quantum entanglement in magnonic systems and how non-

equilibrium states are making a difference on the coherence. Translated into the language of

posthuman theory, superposition calls into question the stability of individual identity, arguing

that the self is not a fixed entity but an emergent property of observation and interaction. This

concept is particularly relevant to speculative fiction, in which protagonists often inhabit

multiple realities simultaneously. Instead of having a singular, unified self, they are a collection

of overlapping identities. Doubt undermining the seeming stability of inhabiting such a

framework demands an honest reevaluation of agency. If a person can be in many possible

states, then his decisions may be probabilistic and may not be deterministic. This further

complicates moral responsibility, as now choices are not absolute but dependent on the act of

observation itself.

From this comes the complementarity principle which says that reality behaves

differently depending on what basis you measure it. Bohr suggested that, depending on the

experimental setting, a particle can show wave-like or particle-like behavior, leading to a

conclusion that parts of existence are determined by observation. This complementarity is not

just limited to physics itself; as Powers and Haus (2017) indicate, it bears on a variety of other

debates, including those on perception and ontology. In posthumanist thinking, it implies that

identity is not an essentialist property, but a relational construction that depends on context. For

example, Barad (2017) argues that selfhood is agentic not because of pre-existing structures that

enable action, but rather because it is always already entangled through intra-actions, whereby

agency belongs to the material-discursive entanglements. In multiversal works of fiction, those

who exist across parallel realties undergo this firsthand, as their identity shifts based on the

timeline they find themselves in. Such stories suggest that selfhood is not singular but

contingent and requires continual negotiation. By arguing that individuals are not necessarily

autonomous agents but instead dynamic agents within a flowing ontological field (this flies in the

face of anthropocentric models of agency, which posit that) Identity in its complementarity

reflects the dynamics of fluidity in quantum mechanics, highlighting the relationality and

malleability of posthuman subjecthoods.

Multi-dimensionality, quantum entanglement, and nonlinear temporality demonstrate the

instability of the self within multi-universal terms. The onset of many-body quantum systems,

whose interactions escape the realm of conventional physics, has explored a new landscape of

entangled states interacting in ways that we now know are not just an academic exercise. Erhard

et al. (2020) argue that these trends offer a finer-grained depiction of how entities relate on

multiple, varied axes, and that this emphasis counters the popular narrative of separability.

Zhang et al. government approach to the Iranian nuclear deal Darehty et al. Posthumanism

theoretical perspectives regard identity as emergent and processual, rather than only being

defined by its stable components. This problem is exacerbated in speculative fictions with

nonlinear temporality, setting up scenarios in which past, present and future both work with and

against each other in unexpected ways. These stories dig deeper into the entangled foundations

of agency, a world in which one’s identity is not constructed through independent actions so

much as the end result of infinite entangled paths. As such, this destabilization of linear

temporality means that identity formation is a recursive process that emerges out of an

interaction that spans classical chronological order.

The Fractured Self

Multiplicity and Identity in Multiversal Beings

In multiversal contexts, it is hard to sustain normative conceptions of selfhood because

of identity fragmentation. This is the framework for understanding how beings manifest across

multiple timelines as proposed by Gilles Deleuze with his idea of difference and repetition.

According to this theory, repetition engenders not replicas but differences that transform the

original, blurring the concept of a coherent singularity. Rosenberg et al. (2024) contend that

multiplicity makes linear understandings of identity untenable as the self is, rather, a collection

of intersecting potentials. Qin (2020) state that they have so far seen this phenomenon that is like

a multiverse where people are interacting with versions of themselves that could only have arisen

in different browsing sessions, which could hypothetically only arise in different realities where

people had made different choices or taken different steps. In the context of this fragmented

evolution of reality in science fiction, Hills, Telotte, and Duchovnay (2015) investigate the

identity formation process and how the characters embody broken parts of themselves while

intermixing realities in films such as the Blade Runner and Star Trek series. These stories

illustrate the mutability of personhood, where identity is a site of multiple potentialities rather

than fixed essence. Their sense of self becomes complex as people exist with them across

multiple timelines, embodying the titular nonlinear behavior of existence. These echoes of

identity weave a tapestry that ties these divergent experiences together, suggesting that the self,

rather than being unitary, is a constellation of infinite, interlacing paths.

In multiversal contexts, the collapse of differences between original self and one of the

duplicates disrupts identity. Jean Baudrillard’s theory of simulacra illustrates how copies can

render the original obsolete and even “better” than itself, creating murky waters between the

authentic and the imitation. Qin (2020) explains how multiverse narratives disrupt conventional

interpretations of individuality when characters can live in multiple realities at the same time.

However, this multiplicity brings about an ontological uncertainty, as characters are forced to

confront the reality that their experiences are not singular, but repeated across an infinite

diversity of becoming. In Everything Everywhere All at Once, Maskell (2024) describes how the

protagonist encounters different versions of herself, each one embodying a different choice that

she could have made. The boundary between these identities has collapsed to represent the

postmodern condition, wherein reality and simulation are hard to distinguish. This blurring of

selfhood undermines the idea of having a singular, authentic identity, proposing instead that the

self is a collection of overlapping possibilities. In navigating these fractured realities, characters

must come to terms with the existence of various versions of themselves, each valid in their own

way while inherently different from the others. This sense of multiplicity calls into question

familiar notions of personal identity, foregrounding the fluid, contingent nature of selfhood in a

multiversal context.

Such multiversal reframing of over-objectivition of identity leads to phenomenological

changes affecting how one views self and reality. Wellner (2020) introduces the theory of

multistability and how the mind perceives the same phenomenon differently based on context.

This is perhaps fundamental to an understanding of not just how we relate to identity as

individuals in a multiverse storyline, but how each iteration of yourself stands for a permutation

of possibilities, if you like. This idea is part of what Sudhakaran (2023) discusses in Everything

Everywhere All at Once, describing how understanding herself in relation to her alternate selves

rewrites the protagonist's idea of personal agency. The perception of and interaction with these

other selves leads to an expanded perception of consciousness where identity is not limited to

one narrative but spreads among many realities. This broader consciousness calls into question

traditional phenomenological notions of selfhood, suggesting that identity is an agile construct,

not an innate essence rooted in the corporeal body. This leads to a conflict between them, dealing

with continuity and divergence between the timelines and their choices. These multiple

standpoints enable us to see ourselves in a more complex way; we are not simply the sum of our

experiences, but rather who we are in relation to others and the imaginary worlds we invent. It is

this sense of interconnection that engenders an appreciation for the richness and arbitrariness of

human existence as it unfolds with each passing moment, particularly as identity becomes fluid

and dynamic as we traverse the multiverse.

Multiversal identity existing within a context makes the construction of selfhood all that

more complex. Rosenberg et al. (2024) insist that multiplicity disrupts classical rails of identity

and compiles people as dynamic assemblages of interconnections. These relate to “thick

imaginations” found in stories that weave personal and cultural identities and multiple realities,

even between those in a layered and intersecting body of experience in time. Multiverse

narratives expose the fluidity of cultural identity (Qin 2020), individual people move through

different cultural contexts on multiple planes in parallel timelines. This plurality provides a sense

of cultural hybridity in which individuals fuse aspects of different realities into their identity.

According to Maskell (2024), this is evident in Everything Everywhere All at Once, where the

protagonist's realization of her alternate identities offers her an opportunity to combine the

warring elements of her identities for a more cohesive self. This is where the multiple facets of

the matryoshka doll play a significant role in shaping the protagonist's perception of her cultural

identity, and Sudhakaran (2023) delves into the intricate connection between the individual and

the group, both dynamically entrenched within one another. The reception of multifaceted

cultural viewpoints leads to a more complex understanding of the self, which is formed both by

unique lived experiences and external influences on identity formation, even outside of your own

culture. This convergence of personal and cultural multiplicity serves as a microcosm of the

broader postmodern condition and the way it renders the traditional, more bounded forms of

identity spectrum to be eclipsed by a suppler and complex understanding of selfhood as diverse

and interdependent. With the complex existence of alternate universe(s) with many different

versions of the individual due to many different cultural and social influences there is not only

the debate of whether these other beings are “the same;” but also theirs the implications of

crossing into different worlds that would shape up an average human. Seeking a union that

embraces seemingly disparate aspects mirrors this process of integration and transformation

through understanding multiversal identity, as the engagement with possible beings opens

themselves to the reinterpretation of life in reflection of this knowledge.

Time Loops and Recursive Causality in Posthuman Agency

By suggesting that outcomes can come to influence their preceding conditions, recursive

causality is at odds with the linear model of cause and effect. This cyclical relationship lies at the

heart of cybernetic feedback loops, which serve to regulate systems by adjusting behavior based

on past results. Wiener’s information theory treats feedback as a mechanism that allows systems

to maintain stability over time even as they respond to changes in the environment. According to

Lushetich (2022), recursive causality reconfigures agency through a framework that casts

individuals as both ends and means of their conditions. While this idea is in line with

posthumanist approaches that refuse a self, exact and sovereign. Agency instead emerges through

the myriad, dynamic interactions of human and nonhuman actors in these complex networks. Hui

2019 also builds on this concept by tracing the dynamic of recursivity in which systems construct

their own present, using their current actions not only to determine future states, but also to

determine the conditions of having taken those actions. In speculative fiction, recursive causality

often takes the form of time loops, repeatedly confronting characters with the repercussions of

their choices. It is a cyclical structure that blurs time between determinism and free will, with

individuals having to navigate situations that require their choices to both inform future events

and be informed by them. By repeating these loops, one can see agency shifting, how an event is

not a singular occurrence but a node in an ongoing feedback loop. These narratives that

challenge traditional notions of linear temporality by mapping the recursive nature of causality

point instead to identity and agency as emergent properties of ongoing processes of adaptation

and self-reflection.

However, there is a new layer of complexity introduced in such systems regarding

determinism versus free will as the pipes become recursive themselves. Whitehead’s process

philosophy stresses that reality is a series of interrelated events and not a static entity, which

means that every event is a product of the relations among previous conditions that have

unfolded. Larrivee (2020) takes this line of thought and extends it to the idea of posthuman

agency, positing a view in which people are embedded in networks of influence that guide their

decisions, but one which offers room for adaptive responses. Ask not what you can do for work,

but what work can do for you, which in this framework is to suggest that agency comes not from

absolute determinism but from the ability to act between and upon these networks. This is also

what Kewin (2023) addresses in speculative fiction, where characters encounter situations that

essentially have them running up against the limits of their autonomy in recursive systems. These

stories represent meetings where these people have to confront what they have done time and

again, so the question arises whether these actions are really free or free will, whether their acts

are unavoidably predestined by the circular nature of their encounters. This balance between

repetitive practice and novel creativity opens a delicate dance of agency in recursive systems,

where any choice made is affected by past impressions and available for future iterations. This

recursive model emphasizes the entanglement of time and identity; it implies that selfhood is not

a static substance but an ongoing modality in which cause and effect coevolve with one another

over time.

Dynamic notions of nonlinear causality in speculative fiction subvert the typical ordering

of time by showing worlds where time folds on itself, and recursive feedback flips the plot.

Recursivity enables systems to adapt to changes in their environment by constantly reassembling

themselves, forming networks that are subject to constant modification (Hui 2019). In similar

ways, Boetzkes (2022) further develops this notion by tracking the formation of posthuman

agency in the interstices among human and nonhuman forces within these networks. In sci-fi,

time loops are often metaphors for the iterative nature of coming of age, repeating scenarios

until characters learn to break deterministic cycles. These stories explore the tension between a

wish for agency and that which is defined by recursive systems. As per Lushetich (2022), the

characters’ repeated interaction with the same chain of events forces them to re-examine their

decisions, shining a light on the cumulative effect of their behavior across iterations. This

cyclical structure questions how singular and linear identity can be as it demonstrates how the

self is formed through recurring experiences with identical situations. The posthuman condition

is shaped by the advantage of recursion, a phenomenon where identity emerges in a constant

cycle of transformation. Speculative fiction renders agency as fluid, dynamic, recursively causal,

by portraying characters who navigate nonlinear temporalities.

In speculative fiction, time loops are often invoked as literary devices to probe the ethical

and existential entanglements of recursive causality. According to Lushetich (2022), posthuman

agency stems from the potential to affect and be affected by one’s surroundings, resulting in a

feedback loop that informs identity and behavior. Hay (2021) explores this idea within Isaac

Asimov’s Foundation universe, where the actions of characters echo through time, impacting

their own predicaments and the arc of history in general. The repetition of critical moments

compels people to deal with the ills of decisions made across time, scooping up all of past,

present, and future in a wringer of consequence. With this cyclical structure, traditional notions

of linear temporality are challenged, communicating that identity and agency are delineated

through iterative processes of adaptation and self-reflection. According to Hui (2019), these

characters, whose stories unfold in these recursive systems, highlight the flexibility and

dynamism of posthuman identity. We are always doing many different things in many different

states and settings, and yet our actions can connect to each other across time and space in a

network of influence that expands beyond newly defined boundaries.

In speculative fiction, the recursive nature of causality indicates the fluid relationship

between agency and temporal iteration. According to Larrivee (2020), posthuman identity

emerges through the ongoing engagement of the person with the environment (both the human

and the non-human), through the formation of ecological networks of influence. Kewin (2023)

engages with this idea in stories where choices lead characters to have to relive more than once

the aftermath of their decisions, demonstrating the compounded nature of these happenings in

back-to-back iterations. This cyclical structure resonates with the idea of identity in a pagan

context as a form of ritualized reenactment; rather than something established or discovered,

selfhood is constructed through processes of continued adaptation and reconfiguration.

Speculative fiction further elaborates the interdependent nature of posthuman agency by figuring

characters who experience or navigate non-linear temporalities.

Posthuman Perception

Sensory Experience in Nonlinear Timelines

Posthuman perception changes human machine mentality into a relation between two

variants of the process, by extending thinking beyond the brain. Cognition Does Not Always

Happen Between the Ears, Andy Clark and David Chalmers’ Extended Mind Hypothesis Andy

Clark and David Chalmers proposed the idea that cognition does not necessarily happen just in

the human body but also occurs in an extended idea of the human brain that includes social

cognition as well as using tools and environments to facilitate cognitive processing. It

recontextualizes sensory experience in which machines become parts of perception itself.

These hybrid interactions lead to posthuman aesthetics, according to Micali and

Pasqualini (2019), resulting in sensory experiences that dissolve the line between the organic

and artificial. This perspective challenges conventional views of identity framed through an

anthropocentric lens, suggesting instead that selfhood is built through relational connections with

nonhuman others. Garcia (2024) builds upon the angle of sensory perception by investigating

how posthuman architectures transform the experience by interlacing digital interfaces within

physical environments. Cognitive botanists cultivate these augmented sensory fields with deeper

layers of sensory perception, opening channels of human awareness alongside and even perhaps

feeding the dumbed down version of the natural world. This blending changes the way people

perceive time and space to become flexible perceptual states without boundaries. With the

sensory barriers we rely on melting away, people explore spaces where the corporeal and digital

intermingle, recalibrating their presence and agency. As such, it invites a reconsideration of the

self not as a unified, corporeal entity, but rather an identity arising in the midst of energetic

exchanges with expanding sensory horizons. According to Garcia (2024), posthumanism

expands the sensory realm by way of technology, placing humans into a network of

interconnected systems that contribute to their reality. But this realization that so much of our

world is the result of simulated feedback does offer some really interesting considerations for

your identity, agency, and what it means to be human in a world mediated by technology.

Posthuman sensory augmentation enriches our existing human faculties through the end-

to-end incorporation of technology within our biological systems. This concept has been

explored in transhumanist literature, in which characters perceive their environment fractured

through focusing lenses that exceed biological capability. Sensory enhancement also allows

humans to perceive previously closed doors, allowing their perception of space and time to

change as well (Rooney 2016). Following this line of thinking, Hackett and Somerville (2017)

interrogate how such engagements with more-than-human environments help cultivate novel

perceptive modalities. Personhood can expand beyond earthly matter while implying

relationships across all organic and inorganic, human and nonhuman, selves and worlds.

Somewhere in speculative fiction, augmented characters traverse complex environments with

augmented senses, perceiving electromagnetic fields, digital data streams, quantum fluctuations

as they navigate work and home. This modification correlates the subject to new limits of human

experience. Humans, as hybrids of the bio-logical being, are able to process whatever world is

analogous to its conclusions. The lines blending between natural and artificial perception mean

that as sensory augmentation becomes more entrenched in everyday life, there is a continuum

stretching into the distance where human and machine senses meet. It shifts the meaning of what

it is to experience the world, implying that perception is not necessarily contained by biology,

but can also be expanded and transformed via technological enhancement. Rooney (2016)

conclude that the interplay between biological and technological cognition creates a new

synthesis of what it means to feel and perceive, with subjects finding themselves in a continuum

of sensations that transcend corporeal boundaries.

Posthuman sensory augmentation changes the way that individuals understand time,

leading to temporally transcendent experiences. Rooney (2016) claims that the sensory

engagements with nonlinear environments allow a subject to sense temporal flows as dynamic

and interconnected, rather than as sequential. Building on this, Pierce (2024) argues that

posthuman perception is no longer bound to a singular temporality, allowing for multiple

temporalities to be experienced in a moment that defies the dominant model of chronological

progression. That broadening of the temporal experience finds its most vivid expression in the

world of speculative fiction, where augmented characters traverse a timeline of overlapping and

interlocking pathways. Their awareness of temporal dissonance reconfigures their sense of

agency since they can see how their actions might play out in the future while know where they

currently stand in time. This imagination of non-linear causation overturns the notion of time as

a fixed arrow, and instead treats it as a fluid network of possibilities. According to Rooney

(2016), posthuman perception reimagines the frontiers of experience by combining sensory

augmentation with temporal awareness, enabling individuals to traverse temporal contexts that

transcend the constraints of biological cognition. The resulting cross-temporal identities offer a

structure of identity that incorporates a multitude of different timelines that can connect

elsewhere, providing an extremely deep perspective on the self and its relations to others

moving forward. Instead, there is a sense of fluidity that the temporal experience they have

affects both their understanding of continuity and change, and how they participate with it, with

past, present and future coexisting with each other in complex and unpredictable ways.

The new switching on of sunspace multiverses create perceptually distorted realities that

call into question the very existence of conventional notions of selfhood and of reality.

Posthuman perception, Hackett and Somerville (2017) claim, manifests through engagements

with more-than-human environments, shuffling the individual's sensory experience. This

cognitive dissonance prompts users to make sense of the fragmented reality they are presented,

as further explicated by Pierce (2024), which only occurs through sensory modalities presented

by multiple realities. In genres of speculative fiction, protagonists weaving their way through

multiversal climates find themselves with partial sensory vectors from disparate timelines,

overlapping impressions for the audience and fragmenting sense of presence. Here, he

compounds perceptual distortions that subvert the stability of identity, forcing people to

reconcile sensory data with absurdities inherent to ordinary logic. Multiple simultaneous views

of alternate realities induce cognitive overload, breaking the coherence of the self. Identity

becomes fragmented through the senses, a posthuman product generated through the manifold

workings of systems [outside] the limits of biological perception. In doing so, this creates a

sense of dissonance that calls into question the accuracy and dependability of sensory inputs,

challenging conventional notions of perception and comprehension of the world around us. This

perspective contests the idea of a singular, coherent individual, arguing that identity is produced

by the synthesis of inharmonious, often conflicting, sensory impressions. Through such

posthuman characters who exist through these perceptual and perceptual distortions, speculative

fiction illustrates posthuman identity in a world of multiversal complexity as something fluid and

dynamic.

Its concept of space also extends itself into cyber-dimension, as posthuman sensorium

encompasses both real and virtual textures into a single sensual landscape. According to Micali

and Pasqualini (2019), in this fusion emerges a relational mode of perception of being in space,

which is to have it as a filament of things that are networked with each other. This idea is

expanded by Garcia (2024), who investigates the way posthuman architectures transfigure

spatial perception via immersive digital interfaces. These environments serve as hybrids where

the material and informational worlds interleave, enabling them to recognize the data embedded

in their environments. Such an integration not only highlights the bewildering limit to our

perception of the real world but also means that spatial settings are no longer bound by fixed

edges but continuously changing in the flow of matter, energy, and information as sensory

interactions unfold. In more speculative works of fiction, characters with augmented perception

traverse environments where digital elements overlay their physical surroundings, a perceptual

layer enhancing the ability to interpret and interact with physical objects and virtual properties

alike. This augmented spatial perception reshapes the interplay between individuals and their

surroundings, enabling them to engage as actors within city infused by biological patterns as well

as synthetic alternatives. The re-contextualization of bodily and digital perception forms a fluid,

interrelated sensory continuum, where the distinction between subject and object ceases to exist.

You are recorded way beyond your body in polity amd through this integration of digital and

physical perception, posthumanism transforms the existence of spatial experience by grounding

individuals in an interconnected web of sensory relationships through which they understand the

world.

This blending of human and machine perception expands sensory experience by taking

cognitive processes outside of organic boundaries. To know more about how technology has

changed our sensory perception, read this interesting article here. In Pierce (2024), this idea is

developed further via a claim that posthuman forms of perception allow for the intimation of

non-linear temporalities and multiversal spaces. Such a broadened field of perception

destabilizes forms of specific, fleshy subjectivity and instead asks us to understand identity

through contact between active assemblages of organic and transhuman elements. It transforms

the experience itself by opening psychic perception beyond biological limitation, in which

people are not mere outsiders but instead gratuitous artists of an infinite cycle of systems

determining the way in which they experience reality.

Quantum Ontology and the Collapse of Human-Centric Reality

Moreover, recent research into the nature of quantum reality indicates that the world is

not centered around human perception. Graham Harman’s object-oriented ontology (OOO)

claims that objects exist independently, having relations to other objects and possessing

properties that do not rely on human observation. From this point of view, anthropocentrism is

destroyed since it does not make man a reference point for understanding existence. Miraval and

Quintana (2023) build upon this critique and call for an adaptive humanism that acknowledges

interconnectedness over human supremacy, employing quantum concepts to do so. Lewis (2016)

takes this line of thought into the implications of quantum mechanics for ontology and finds that

phenomena exist probabilisticly until they are observed. Comprised of these attitudes, they

challenge a reality that is a bundle of associated asteroids, each with a life of its own beyond

human thought. This orientation upsets the traditional subject-object dichotomy, making humans

one among many actors in a system of reciprocity. Posthumanism’s emphasis on relationality

and interconnectedness is mirrored in quantum ontology by the way it decentralizes human

perception, it situates identity within a multiversal framework in which humans occupy the same

integrative, multi-embodied modality as they do in a dynamic quantum reality in which they are

not privileged observers but rather enmeshed actors.

Confalonieri and Guizzardi (2023). states that Timothy Morton’s concept of

hyperobjects also complicates anthropocentric perspectives, describing entities that are

enormous, spread out, and transcend human understanding. These objects, such as climate

change and the global internet, defy individual perception and span spatial as well as temporal

scales. According to Confalonieri and Guizzardi (2023), these assemblages cannot be understood

through linear, human-centered models, but rather through relational frameworks that embrace

distributed agency. In the context of quantum mechanics, Allori (2019) describes this transition

as one in which phenomena do not exist in isolation, but participate in a larger web of

interactions, from which we draw useful distinctions. Adel and Alani (2024) assert that this

attitude reflects a posthumanist viewpoint in that it opens up the possibilities of identity beyond

the corporeal human body and highlights the emergence of the self through contact with more-

than-human systems. Speculative fiction narratives following hyper-objects oftentimes delve into

the psychological and existential repercussions if and when one encounters an entity outside of

human understanding. As their characters confront these entities, they encounter shifts in

perception that blurs the line between agency and submission, revealing the posthuman

experience where interaction with external forces informs the essence of self. This exploration of

the encounter with hyper-objects reveals the disintegration of anthropocentric reality, and

demonstrates the frame of interconnectedness and distribution of existence (the essence of

relational models) necessary for survival.

While in classical physics we can provide separate mentions of definitions and rules of

engagement in between subject and object, quantum mechanics proves that any observation

affects established properties of a particle, so that indicates not only that the world is ambiguous

but also that it is contingent. This phenomenon, Lewis (2016) contends, undermines traditional

metaphysical assumptions, insofar as measuring a particle causes its probabilistic state to

collapse into one particular outcome. Miraval and Quintana (2023) follow this logic and address

identity through the lens of human experience, arguing that rather than being an unchanging

essence of persons, identity is formed in a particular way as persons relate dynamically with the

environment. This view is congruent with speculative realism, which denies reality as another

world created or in tension with humans. Speculative realists, on the other hand, argue that

objects have properties outside of human perception, contradicting the anthropocentric

assumption that existence is contingent upon human observation. Speculative fiction involving

quantum phenomena often debunks the distinction between observer and observed, without

resorting to fallacious pseudo-science. Multiverse characters experience a fragmentation of their

identity, as they exist across branches of probability sequences, creating composite personas that

occupy multiplicative realities. The collapse of classical distinctions recasts the notion of agency,

implying the unsustainability of the atomism of individuals who are plucked from their context

and treated as isolated actors, when in fact they are nodes in a structure as much alive and fluid

as they are. These narratives emphasize the fluid and contingent nature of reality itself,

subverting the ideas of selfhood itself, instead emphasizing that identity ought to be considered

an emergent property of relational processes that are thought to exist beyond the human mind.

A posthuman identity is based on a relational ontology, which highlights

interconnectedness as opposed to individualism. As Confalonieri and Guizzardi (2023) argue,

ontology (in this case, in the context of explainable AI) demonstrates that systems create

meaning through relations. Systems create meaning through interactions with their environment

as opposed to through isolated processes. This lens dovetails with Morton’s notion of

hyperobjects, which demonstrate how things exist beyond the individual or the collective, but

that still affect identity, personal or communal. Adel and Alani (2024) take this approach to the

next level, exploring the implications of human-machine teaming in smart cities, with embedded

distributed networks programming our every day. Speculative fiction, which turns its gaze

towards the future, focuses on posthuman subjectivities, the ways people navigate domains

populated by other bodies and things that are both organic and synthetic. We have characters

who were shaped by hyper-objects and quantum events, whose worlds felt changes so strong as

to constantly question the existence of an individual, unified self. Rather, identity is seen as a

fluid and dynamic construction with this space between us and the visible and the invisible. This

relational ontology reconceptualizes agency not as the result of some isolated entity but as

participation in a larger system of connected processes. And this is precisely what speculative

fiction does, in portraying characters confined within these intricate webs of interaction, it shows

the posthuman condition, wherein neither identity nor agency are restricted to the human body,

but instead arise through interactions with a world that transcends the capacity for human

perception.

Quantum ontology subverts the presumption that being is knowable objectively, tending

instead to posit existence as probabilistic and relational. Quantum mechanics, according to Allori

(2019), reshapes the classical view of the universe as deterministic to report outcomes that

depend on observation. Miraval and Quintana (2023) extend this principle to the realm of human

experience, emphasizing that our identity and perception are not simply a projection, but rather

emerge from interaction with a world that exists outside of human thought. Such a view is

sympathetic to speculative realism, which denies that reality consists solely inside the human

mind. Speculative realists, on the other hand, believe that objects inherently possess properties

that are independent of human perception. And in speculative fiction, stories resonant with

quantum phenomena tend to subvert the classical divide between subject and object. Characters

who will experience multiple realities all at once, and with that the fragmentation of identity and

self across a population of possible states. According to Lewis (2016), such stories have all kinds

of implications, showing how the reality we construct is a slippery, conditional kind of facts that

critiques nottraditional notions of the self but confirms identity as a product of relational

processes that are orders of magnitude beyond what the mind can know.

Identity and agency are redefined within a multiversal framework, with reality collapsing

in on itself. Adel and Alani (2024) argue human-machine collaboration in smart cities shows

how interlocking systems inform human experience, both personal and collective. As Lewis

(2016) elaborates on this outlook, he believes that quantum mechanics is an attempt to replace

the pre-quantum deterministic model of reality, which assumes the existence of a fixed reality

determined prior to observation, with a new one in which the outcome of the observation

depends on the observer. This move connects directly to posthumanism, where relationality and

interdependence are privileged over individual autonomy. The dynamic of multiverse

environments, commonly present in speculative fiction narratives, often examines how people

navigate identities transcending various realities. These characters undergo shifts in perception

that call into question the idea of a singular, coherent self, implying instead that identity is fluid

and contingent. The dissolution of classical subject-object distinctions reconceptualizes agency

such that individuals (the new subject) are now considered participants in networks of influence

that far surpass the contours of the local. Speculative fiction, by showing that the characters

must navigate these complex systems, lays bare the posthuman condition that identity and

agency crystallizes through interactions with a world that not only exists without human

perception but is indifferent to human ends. These relational ontology challenges standard notion

of selfhood proposing that self is not a given essence but an emergent property of relations, a

carrier of dynamic processes inscribed on social, political and sexual bodies that overflow

symbols, the limits of the human mind.

Ethics of Multiversal Existence

Morality Beyond the Human

In a world where multiversal existence can be a thing, traditional ethical frameworks are

often tested, as individuals can theoretically encounter an infinite number of alternate versions

of themselves. Francesca Ferrando’s posthuman ethics underscores relationality and

interconnectedness, demonstrating that any ethical consideration must include interactions

between human and nonhuman agents. This departs easily into multiversal territory and

nonlinear time, suggesting that what happens in one reality can change infinite others. As such,

Hutchings (2019) asserts that moral principles need to be grounded in the realities of the

pluriverse, where ethical paradigms are not context-agnostic, but rather formed by the unique

perspectives that make up the whole. This stance pushes back against the universalizing of

ethics, which would require morality to exist in just one reality. In this regard Ludvig (2024) has

added to this perspective by arguing for the multiverse underpinning biodiversity and ecological

balance, and placing the nonhuman as players in ethical deliberations. These perspectives

confront anthropocentric ethics, proposing moral accountability to include not only human

matters but also the intricate web of life. In speculative fiction, multiverse-attuned characters

often face ethical dilemmas that explosively challenge them beyond mere self-interest. Their

choices affect alternate all of themselves and other beings, suggesting limits on personal

responsibility. Speculative fiction, through its portrayal of characters who struggle with the

repercussions of their actions across realities, highlights the need for ethical systems that

consider existence as fundamentally interrelated and relational. The turn towards a more

pluralistic and context-savvy morality fits within posthumanism’s valuing of relationality,

providing a bedrock for negotiating the ethical complexity of multiversal living.

Through a lens of relationality and interconnectedness, posthuman thought critiques

anthropocentric ethics. This is about the connected nature of all that exists, as Ferrando tells us

and it is what forms the basis for an ethics of responsibility that is not limited to human agents

but extends to nonhumans. Rather, through a lens that, as Ludvig (2024) reasserts, derives its

moral framework from the multiverse, biodiversity becomes a function that places nonhuman

life at the center of ethical “concerns”. This understanding beseeches models of frameworks that

place humans above nonwhumans, and asks for some sort of relational ethics that respects the

sovereignty and agency of both humans and nonwhumans. Posthuman ethics invites us to

expand our moral circle of consideration beyond ourselves and other humans to the complex

interdependent relationships that makeup multiverses. In speculative fiction, where characters are

forced to adapt to their environments through dynamic interrelations with organic as well as

artificial beings, this line of thinking becomes especially powerful. The family’s actions have

consequences that reverberate out into both their environment and other alternate worlds,

illustrating that making ethical systems requires an understanding of connection and relationality

(Chen, 2023).

Paradoxical selfhood and multiverse raise ethical questions about identity and agency.

Herbrechter’s posthuman ethics contested the ideal of an entire, autonomous self, proposing that

identity arises through relations with both human and nonhuman others. From this point of

view, Hutchings (2019) takes it a step further by arguing that not only should ethical frameworks

recognize the diversity of experiences (the pluriverse) but that morality is contingent and

relational in nature and thus, must be understood through context as well. In multiversal stories,

characters frequently meet alternate versions of themselves who are altered by different choices

and circumstances. As per Qin (2020), this multiversality of selves poses challenging questions

for personal responsibility, as people have to consider the ramifications of actions taken by their

other selves. As far as fiction goes, the one that speaks of multiple worlds, at varying levels of

probability, where decisions lead to different outcomes, generates a more complex conception of

accountability, one where ethical behavior cannot just focus on individual outcomes, but also

includes a push or pull in the direction of a collective whole. For example, by illustrating

characters who struggle with the implications of their multiversal existence, speculative fiction

offers contrast to the ethical complexities of operating in a world where each identity is fluid and

interdependent. Here, we reach a point where Posthuman ethics transitioning relationality offers

a telos for understanding morality in a way that acknowledges the dissolution of self and utter.

Quantum immortality also adds another layer to the ethical question, as it would mean

that people would always exist in another reality regardless of the choice they make. This idea

subverts conventional wisdom about dying and accountability by suggesting that the acts of one

human being are meaningless. Youvan (2024) considers the possible implications of quantum

immortal hypostasis on morality, observing that moral agents knowing they will persist as a

consequence of their actions may make moral behavior less important. But as Chen (2023)

notes, ethical responsibility still matters if we are to decide how we ought to act towards others

whose lives will be affected by our choices, through our universe as well as through the

multiverse. This tension between personal consequence and collective responsibility mirrors the

more general ethical dilemmas inherent in multiversal life. In speculative fiction, characters who

are faced with their own immortality are usually forced to realize that the consequences of the

things they do matter more than any immediate borders that define their reality. This has led to a

growing awareness that creates a moral imperative, how can a person continue to exist across

multiple realities while wrestling with the ethics involved? According to Hutchings (2019), in

creating characters who engage with these dilemmas, speculative fiction reflects the need for

ethical frameworks that recognize the interrelated and relational quality of being, and provides a

more nuanced understanding of morality in a world in which the distinctions between life and

death are increasingly porous.

These scenarios are very relevant to artificial intelligence as well, as both of the

Schrödinger’s cat thought experiments express the ethical implications behind the probabilistic

existence. The thought experiment points to the uncertainty at the core of quantum mechanics,

where something can exist in several states at once until a person or thing makes a measurement.

Building on this concept, Qin (2020) suggests it pertains to multiversal ethics in that one

individual must contend with the moral ramifications of an act having potentially different

outcomes in nearby realities. Extending this work, Chen (2023) investigates the influence of

outcome uncertainty on ethical choices, in which the state of the forced choice can be either

observed or unobserved, with meaningful decisions being made. Our probabilistic experience

thus undermines providential and deterministic conceptions of ethics, as such conceptions must

plainly reckon with the risk of multiple outcomes. Across speculative fiction, characters who

wade into the gray areas of the ambiguous morality of their actions can get left in the moral

lurch when forced to work through outcomes of a scenario that do not present themselves until it

is simply too late. The uncertainty about what is real and what is not raises a feeling of larger

ethical obligation, where one must consider the effects of what they do in both the known and

unknown worlds. Chen (2023) believes that speculative fiction demonstrates the complexity of

probabilistic existence, offering a deeper frame for how morality works, creating ethical

playbooks for working within an interlocked, terrified multiverse.

Importantly, multiversal existence raises a wide range of concerns surrounding free will

and moral responsibility. At the same time, Hutchings (2019) points out that ethical frameworks

need to evolve to account for the diversity of experiences in the pluriverse, since people engage

with and in environments that are determined as much as by their choices as by those choices of

others. Youvan (2024) builds upon this idea, contending that such knowledge of alternate

realities renders free will an even more complex issue, since one must contemplate the

ramifications of their choices on countless timelines. This awareness creates a moral

responsibility, for individuals know that the decisions they make affect not only their current

environment, but also different choices of themselves. In speculative fiction, characters who

face such a multiplicity of outcomes struggle with the ethical ramifications of their actions —

there are consequences, they recognize, for choices that branch out from them. This expanded

sense of duty intersects the posthuman ethics that consider relationality and interconnectedness

as the foundations of responsibility and allows for a theoreti-cal breakthrough into the moral

dilemmas present in a multiverse. Speculative fiction demonstrates that considering identity and

agency as an interwoven and fluid tapestry necessitates frameworks that take these nuances into

account, and the characters who grapple with these issues serve as a mirror for the difficulties

connecting to the complexity of ethical relationships in the world of our shared collective home.

The ethical complexities of multiverse existence in the multiverse called for reevaluation

of moral frameworks. Fulfilling consequences of existing in multiple universes creates ethical

dilemmas that test the limits of traditional morality. According to Ludvig (2024), the multiverse

upholds biodiversity and ecological stability, indicating that responsibility entails more than

human beings. This perception is backed by Qin (2020), who seems to claim that everything is

inherently linked together, and one action in a single reality can have an impact in an infinite

number of realities. This web of interaction poses challenges for anthropocentric ethics and

vocation, pointing to the need for moral responsibility to be attentive to the realities affected by

choices made in one of those realities. Character Ethics, in speculative fiction (SF) multiversal

navigators experience ethical dilemmas that often exceed their individual interests, what they do

affects alternate versions of themselves and other sentient beings. Such awareness creates

feelings of moral duty because you realize that one's decisions have implications that stretch

beyond their immediate environment. Speculative fiction explores these questions by presenting

characters who struggle with these dilemmas and reflects the need for ethical frameworks that

consider not just our isolated individualism, but the interconnected and relational qualities of

existence, and suggests that making ethical decisions is complicated in the nature of a world

where the division of self and other disintegrates. Moving from the Anthropocentric paradigm of

morality more towards posthuman ethics would create a more inclusive, imaginative and

sensitive morality that takes into account relationality and interconnectedness as a key element to

come to moral decisions.

Conclusion

Toward a Posthuman Future of Multiversal Subjectivity

Posthuman identity disrupts anthropocentrism by inserting quantum mechanics,

multiversal theory, and nonlinear temporality into the contemporary narrative. Ferrando’s

posthuman ethics stress relationality, in which whom we are comes into being in relation with

nonhuman and human actors. In other words, this approach is in keeping with Barad’s (2017)

notion of agential realism, which asserts that reality is produced in intra-action rather than

independent of observation. Building on this notion, Lewis (2016) further argued that quantum

mechanics complicate classical conception of identity by showing that existence is probabilistic,

not deterministic where the contextual understanding and implications of this sentence differ

greatly. The erosion of classical subject-object dichotomies renders conventional views of

agency even less tenable, where human subjects are not to be seen as sovereign agents, but

components of shifting networks of active (Meyer, 2022). This transition aligns with Harman’s

object-oriented ontology, which says that objects have agency outside of our perception of them.

Through its characterization of individuals who move through these systems, speculative fiction

represents the posthuman condition, where identity and agency coalesce through engagement

with a world extending beyond the boundaries of human cognition. The redefinition of identity

thus opens up space that directly questions anthropocentric worldviews, creating a political

subject in which all individuals are integral to a wider system and where selfhood is ultimately

ever-changing, relational, and subject to both human and nonhuman forces.

Now more than ever, lie in the anthropophic meta-structure brokering in the spatial

realities of AI, VR, and quantum computing. Confalonieri and Guizzardi (2023) who argue that

AI systems produce meaning in their relations as processes and not simply as objects of

processes, which is a key cosmological theme of posthumanism. In the context of AI-driven

environments that include machine-learning algorithms that are constantly learning and evolving

based on feedback, we arrive at a more complex kind of dynamic, one between the machine and

human users and the machine and other machines. Drawing on those ideas, Garcia (2024) takes

things further, looking at the ways that posthuman architectures introduce digital interfaces into

the material realm and how those interventions modify sensory experience and spatial

perception. VR technologies further obfuscate the line between embodied and virtual

experiences, enabling a multitude of identities to be expressed even across distinct realities. This

sensory enhancement theory directly connects to Clark and Chalmers’ extended cognition thesis,

stating that cognition occurs via interaction with external devices and environments. Posthuman

identity becomes liquid and nonlinear, in resonance with quantum computing as the ability to

process information probabilistically. Quantum mechanics, according to Allori (2019)

undermines deterministic models of reality, supplanting them with systems in which outcomes

are conditional on observation. With these emerging technologies advancing, they will

increasingly inform how people experience, engage with their context, and themselves, a

process that furthers the blurring of human with machine, self with other. This Venn diagram of

AI, VR, and quantum computing provides a picture of the real-life embodiment of posthuman

identity, where sensation, cognition, and spatiality no longer remains embodied in the biological

body of an individual, but stretch across vast networks of human and nonhuman agents.

This is the basis for the exploration of the so-called quantum posthuman, inviting stylistic

exploration of the dissolution of distinction between the imaginary and the real through

multiversal subjectivity. Hutchings (2019) gives voice to an ontological argument for an

ontology of the multi-verse, we are not the same and neither are our experiences and so ethical

models should reflect that & be conscious of the fact that there is no universal moral notion that

can apply when a people leave multiple lives. Qin (2020) assert that, as a matter of course, this

lens is particularly relevant for considering the more general ethical questions posed by

technologies such as Artificial intelligence (AI) and Virtual reality (VR), where people can

interact with digital doubles who express different facets of their identity. Youvan (2024) argues

that this perspective prompts a reevaluation of how we should approach decision-making when

our actions have repercussions not only for ourselves but also for our alternate selves in many

possible worlds. There is much to learn from speculative fiction with respect to these ethical

dilemmas; it is through such narratives that characters confront the consequences of their actions

in multiple timelines. These narrative structures potentially influence public perceptions of

identity and agency; future studies should consider this dynamic, especially as advancements in

quantum computing and VR continue to make new types of multiversal experiences accessible to

wider audiences. This theoretical exploration would enable researchers to construct ethical

frameworks for navigating a subjectivity that is arguably fluid, relational and dispersed across

networks of human and nonhuman actors, networks that are ultimately brought into contact by

the power of contemporary technologies. It is also important in this interdisciplinary approach in

order to navigate in a future psychology in a world with ethical, philosophical, and technological

challenges where like never before the divisions of self and other, of human and machine, of

reality and of simulation are more blurred.
