“Humility is the mother of giants. One sees great things from the valley; only small things from the peak.”

“There is only one thing which is generally safe from plagiarism -- self-denial.”

“I have my doubts about all this real value in mountaineering, in getting to the top of everything and overlooking everything. Satan was the most celebrated of Alpine guides, when he took Jesus to the top of an exceeding high mountain and showed him all the kingdoms of the earth. But the joy of Satan in standing on a peak is not a joy in largeness, but a joy in beholding smallness, in the fact that all men look like insects at his feet. It is from the valley that things look large; it is from the level that things look high; I am a child of the level and have no need of that celebrated Alpine guide. I will lift up my eyes to the hills, from whence cometh my help; but I will not lift up my carcass to the hills, unless it is absolutely necessary. Everything is in an attitude of mind; and at this moment I am in a comfortable attitude. I will sit still and let the marvels and the adventures settle on me like flies. There are plenty of them, I assure you. The world will never starve for want of wonders; but only for want of wonder.”

“The telescope makes the world smaller; it is only the microscope that makes it larger. Before long the world will be cloven with a war between the telescopists and the microscopists. The first study large things and live in a small world; the second study small things and live in a large world.”

“There is only one thing that that it requires real courage to say, and that is a truism.”

“Properly speaking, of course, there is no such thing as a return to nature, because there is no such thing as a departure from it. The phrase reminds one of the slightly intoxicated gentleman who gets up in his own dining room and declares firmly that he must be getting home.”

“The things we see every day are the things we never see at all.”
