I confess I was surprised to find that so many men spent their whole day, ay, their whole lives almost, a-fishing. It is remarkable what a serious business men make of getting their dinners, and how universally shiftlessness and a groveling taste take refuge in a merely ant-like industry. Better go without your dinner, I thought, than be thus everlastingly fishing for it like a cormorant. Of course, viewed from the shore, our pursuits in the country appear not a whit less frivolous.
Henry David ThoreauI should say that the useful results of science had accumulated, but that there had been no accumulation of knowledge, strictly speaking, for posterity; for knowledge is to be acquired only by a corresponding experience. How can we know what we are told merely? Each man can interpret another's experience only by his own.
