Success feeds confidence.

We fly, but we have not 'conquered' the air. Nature presides in all her dignity, permitting us the study and the use of such of her forces as we may understand. It is when we presume to intimacy, having been granted only tolerance, that the harsh stick fall across our impudent knuckles and we rub the pain, staring upward, startled by our ignorance.

Success feeds confidence.

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.

I suppose if there were a part of the world in which mastodon still lived, somebody would design a new gun, and men, in their eternal impudence, would hunt mastodon as they now hunt elephant. Impudence seems to be the word. At least David and Goliath were of the same species, but, to an elephant, a man can only be a midge with a deathly sting.

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.

A map in the hands of a pilot is a testimony of a man's faith in other men; it is a symbol of confidence and trust. It is not like a printed page that bears mere words, ambiguous and artful, and whose most believing reader - even whose author, perhaps - must allow in his mind a recess for doubt. A map says to you, 'Read me carefully, follow me closely, doubt me not.' It says, 'I am the earth in the palm of your hand. Without me, you are alone and lost.
