The modern world has far too little understanding of the art of keeping young. Its notion of progress has been to pile one thing on top of another, without caring if each thing was crushed in turn. People forgot that the human soul can enjoy a thing most when there is time to think about it and be thankful for it. And by crowding things together they lost the sense of surprise; and surprise is the secret of joy.

Sir Hiram Maxim is a genuine and typical example of the man of science, romantic, excitable, full of real but somewhat obvious poetry, a little hazy in logic and philosophy, but full of hearty enthusiasm and an honorable simplicity. He is, as he expresses it, "an old and trained engineer," and is like all of the old and trained engineers I have happened to come across, a man who indemnifies himself for the superhuman or inhuman concentration required for physical science by a vague and dangerous romanticism about everything else.

He may be mad, but there's method in his madness. There nearly always is method in madness. It's what drives men mad, being methodical.

There is no way in which a man can earn a star or deserve a sunset.
