Passed years seem safe ones, vanquished ones, while the future lives in a cloud, formidable from a distance. The cloud clears as you enter it. I have learned this, but like everyone, I learned it late.

One day the stars will be as familiar to each man as the landmarks, the curves, and the hills on the road that leads to his door, and one day this will be an airborne life. But by then men will have forgotten how to fly; they will be passengers on machines whose conductors are carefully promoted to a familiarity with labelled buttons, and in whose minds knowledge of the sky and the wind and the way of weather will be extraneous as passing fiction.

But the soul of Africa, its integrity, the slow inexorable pulse of its life, is its own and of such singular rhythm that no outsider, unless steeped from childhood in its endless, even beat, can ever hope to experience it, except only as a bystander might experience a Masai war dance knowing nothing of its music nor the meaning of its steps.

Success feeds confidence.

the sun is as dispassionate as the hand of a man who greets you with his mind on other things.

No human pursuit achieves dignity unless it can be called work, and when you can experience a physical loneliness for the tools of your trade, you see that the other things - the experiments, the irrelevant vocations, the vanities you used to hold - were false to you.

You can live a lifetime and, at the end of it, know more about other people than you know about yourself. You learn to watch other people, but you never watch yourself because you strive against loneliness. If you read a book, or shuffle a deck of cards, or care for a dog, you are avoiding yourself. The abhorrence of loneliness is as natural as wanting to live at all. If it were otherwise, men would never have bothered to make an alphabet, nor to have fashioned words out of what were only animal sounds, nor to have crossed continents - each man to see what the other looked like.
