One day's exposure to mountains is better than cartloads of books. See how willingly Nature poses herself upon photographers' plates. No earthly chemicals are so sensitive as those of the human soul.
-John Muir, naturalist, explorer, and writer (1838-1914)
Where the spirit does not work with the hand there is no art
- Leonardo da Vinci. Italian painter, draftsman, sculptor, architect and engineer, 1452-1519
