Existential

“If you only read the books that everyone else is reading, you can only think what everyone else is thinking.”
― Haruki Murakami, Norwegian Wood

“An intellectual? Yes. And never deny it. An intellectual is someone whose mind watches itself. I like this, because I am happy to be both halves, the watcher and the watched. "Can they be brought together?" This is a practical question. We must get down to it. "I despise intelligence" really means: "I cannot bear my doubts.”
― Albert Camus

“Any fool can be happy. It takes a man with real heart to make beauty out of the stuff that makes us weep.”
― Clive Barker, Abarat: Days of Magic, Nights of War

“Sin is a thing that writes itself across a man's face. It cannot be concealed.”
― Oscar Wilde, The Picture of Dorian Gray
