Men cannot not live by exchanging articles, but producing them. They live by work not trade.
John RuskinThere is no climate, no place, and scarcely an hour, in which nature does not exhibit color which no mortal effort can imitate or approach. For all our artificial pigments are, even when seen under the same circumstances, dead and lightless beside her living color; nature exhibits her hues under an intensity of sunlight which trebles their brilliancy.
John Ruskin
