“Illness is the doctor to whom we pay most heed; to kindness, to knowledge, we make promise only; pain we obey.”

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

“Knowledge of the thing cannot impede it; but at least we have the things we discover, if not in our hands, at least in thought, and there they are at your disposal, which inspires us to the illusory hope of enjoying a kind of dominion over them.”

“Death is in truth an illness from which we recover”

“To achieve accurate knowledge of others, if such a thing were possible, we could only ever arrive at it through the slow and unsure recognition of our own initial optical inaccuracies. However, such knowledge is not possible: for, while our vision of others is being adjusted, they, who are not made of mere brute matter, are also changing; we think we have managed to see them more clearly, but they shift; and when we believe we have them fully in focus, it is merely our older images of them that we have clarified, but which are themselves already out of date.”

“We are, when we love, in an abnormal state, capable of giving at once to the most apparently simple accident, an accident which may at any moment occur, a seriousness which in itself it would not entail. What makes us so happy is the presence in our hearts of an unstable element which we contrive perpetually to maintain and of which we cease almost to be aware so long as it is not displaced. In reality, there is in love a permanent strain of suffering which happiness neutralises, make potential only, postpones, but which may at any moment become, what it would long since have been had we not obtained what we wanted, excruciating.”

“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.”
