There is a certain silence that can emanate from a lifeless object as from a chair lately used, or from a piano with old dust upon its keys, or from anything that has answered to the need of a man, for pleasure or for work. This kind of silence can speak. Its voice may be melancholy, but it is not always so; for the chair may have been left by a laughing child or the last notes of the piano may have been raucous and gay. Whatever the mood or the circumstance, the essence of its quality may linger in the silence that follows. It is a soundless echo.

You can live a lifetime and at the end of it, know more about other people than you know about yourself.

Africa is mystic; it is wild; it is a sweltering inferno; it is a photographer's paradise, a hunter's Valhalla, an escapist's Utopia. It is what you will, and it withstands all interpretations. It is the last vestige of a dead world or the cradle of a shiny new one. To a lot of people, as to myself, it is just 'home'. It is all these things but one thing - it is never dull.

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.

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.

To me, desert has the quality of darkness; none of the shapes you see in it are real or permanent. Like night, the desert is boundless, comfortless, and infinite. Like night, it intrigues the mind and leads it to futility. When you have flown halfway across a desert, you experience the desperation of a sleepless man waiting for dawn which only comes when the importance of its coming is lost.

I have a trunk containing continents.
