“No doubt very few people understand the purely subjective nature of the phenomenon that we call love, or how it creates, so to speak, a supplementary person, distinct from the person whom the world knows by the same name, a person most of whose constituent elements are derived from ourselves.”

“Only through art can we emerge from ourselves and know what another person sees.”

“The person with whom we are in love is to be recognised only by the intensity of the pain that we suffer.”

“None of us constitutes a material whole, identical for everyone, which a person has only to go look up as though we were a book of specifications or a last testament; our social personality is a creation of the minds of others. Even the very simple act that we call "seeing a person we know" is in part an intellectual one. We fill the physical appearance of the individual we see with all the notions we have about him, and of the total picture that we form for ourselves, these notions certainly occupy the greater part.”

“It was she whom I loved and whom I could not therefore see without that anxiety, without that desire for something more, which destroys in us, in the presence of the person we love, the sensation of loving.”

“The bonds between ourselves and another person exists only in our minds. Memory as it grows fainter loosens them, and notwithstanding the illusion by which we want to be duped and which, out of love, friendship, politeness, deference, duty, we dupe other people, we exist alone. Man is the creature who cannot escape from himself, who knows other people only in himself, and when he asserts the contrary, he is lying.”

“The most exclusive love for a person is always a love for something else.”
