after selecting a central theme or symbol from Conrad's Heart of Darkness, how does it illuminate_no pun intended_your reading of Conrad's work?

i need 1 paragraph: introduction(start with quote) and Thesis

on quote that i liked in the book is "The conquest of the earth, which mostly means the taking it away from those who have a different complexion or slightly flatter noses than ourselves, is not a pretty thing when you look into it too much." part 1, page 7

*if you find better quote that will be good ,but if you see this quote is perfect so go ahead use it
