“People who are not in love fail to understand how an intelligent man can suffer because of a very ordinary woman. This is like being surprised that anyone should be stricken with cholera because of a creature so insignificant as the common bacillus.”

“People who, not being in love themselves, feel that a clever man should only be unhappy about a person who is worth his while; which is rather like being astonished that anyone should condescend to die of cholera at the bidding of so insignificant a creature as the comma bacillus.”

“there are things in our souls which we know not how much they mean to us. Or rather, if we live without them, it is because, either through fear of failing or suffering, we daily postpone the moment of coming under their thrall.”

“Nine tenths of the ills from which intelligent people suffer spring from their intellect.”

“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.”

“Love is not vain because it is frustrated, but because it is fulfilled. The people we love turn to ashes when we posess them.”

“A woman whom we need and who makes us suffer elicits from us a whole gamut of feelings far more profound and vital than a man of genius who interests us.”
