A ruling passion gives to a shelf of novels the unity of a system.

The sense of unhappiness is so much easier to convey than that of happiness. In misery we seem aware of our own existence, even though it may be in the form of a monstrous egotism: this pain of mine is individual, this nerve that winces belongs to me and to no other. But happiness annihilates us: we lose our identity.

However great a man's fear of life, suicide remains the courageous act, the clear-headed act of a mathematician. The suicide has judged by the laws of chance - so many odds against one that to live will be more miserable than to die. His sense of mathematics is greater than his sense of survival. But think how a sense of survival must clamor to be heard at the last moment, what excuses it must present of a totally unscientific nature.

We can love with our minds, but can we love only with our minds? Love extends itself all the time, so that we can love even with our senseless nails: we love even with our clothes, so that a sleeve can feel a sleeve.

Perhaps the sexual life is the great test. If we can survive it with charity to those we love and with affection to those we have betrayed, we needn't worry so much about the good and the bad in us. But jealousy, distrust, cruelty, revenge, recrimination ... then we fail. The wrong is in that failure even if we are the victims and not the executioners. Virtue is no excuse.

You cannot control what you love--you watch it driving recklessly towards the broken bridge, the torn-up track, the horror of seventy years ahead.
