You get towards the end of life - no, not life itself, but of something else: the end of any likelihood of change in that life. You are allowed a long moment of pause, time enough to ask the question: what else have I done wrong?

Perhaps the world progresses not by maturing, but by being in a permanent state of adolescence, of thrilled discovery.

We thought we were being mature when we were only being safe. We imagined we were being responsible but were only being cowardly. What we called realism turned out to be a way of avoiding things rather than facing them.

And that was all the part of it - the way you were obliged to live. You stifled a groan, you lied about your love, you deceived your legal wife, and all in the name of honour. That was the damned paradox of it - in order to behave well, you have to behave badly.

If a man cannot tell what he wants to do, then he must find out what he ought to do. If desire has become complicated, then hold fast to duty.

Life is like invading Russia. A blitz start, massed shakos, plumes dancing like a flustered henhouse; a period of svelte progress recorded in ebullient despatches as the enemy falls back; then the beginning of a long, morale-sapping trudge with rations getting shorter and the first snowflakes upon your face. The enemy burns Moscow and you yield to General January, whose fingernails are very icicles. Bitter retreat. Harrying Cossacks. Eventually you fall beneath a boy-gunner's grapeshot while crossing some Polish river not even marked on your general's map.

When you are young, you think that the old lament the deterioration of life because this makes it easier for them to die without regret. When you are old, you become impatient with the way in which the young applaud the most insignificant improvements … while remaining heedless of the world’s barbarism. I don’t say things have got worse; I merely say the young wouldn’t notice if they had. The old times were good because then we were young, and ignorant of how ignorant the young can be.
