Sitting Quotes - page 46
It is not a man's duty, as a matter of course, to devote himself to the eradication of any, even the most enormous wrong he may still properly have other concerns to engage him but it is his duty, at least, to wash his hands of it, and, if he gives it no thought longer, not to give it practically his support. If I devote myself to other pursuits and contemplations, I must first see, at least, that I do not pursue them sitting upon another man's shoulders.
Henry David Thoreau
