O joy of suffering! To struggle against great odds! to meet enemies undaunted! To be entirely alone with them! to find how much one can stand! To look strife, torture, prison, popular odium, death, face to face! To mount the scaffold! to advance to the muzzles of guns with perfect nonchalance! To be indeed a God!

As to scenery (giving my own thought and feeling), while I know the standard claim is that Yosemite, Niagara Falls, the Upper Yellowstone and the like afford the greatest natural shows, I am not so sure but the prairies and plains, while less stunning at first sight, last longer, fill the esthetic sense fuller, precede all the rest, and make North America's characteristic landscape.

O to speed where there is space enough and air enough at last!

Long enough have you dream'd contemptible dreams, Now I wash the gum from your eyes, You must habit yourself to the dazzle of the light and of every moment of your life

Shut not your doors to me proud libraries.

I like the scientific spirit-the holding off, the being sure but not too sure, the willingness to surrender ideas when the evidence is against them: this is ultimately fine-it always keeps the way beyond open.

The art of art... is simplicity.
