"Mathematics should be mixed not only with..." - Quote by Henry David Thoreau

“The husbandman is always a better Greek than the scholar is prepared to appreciate, and the old custom still survives, while antiquarians and scholars grow gray in commemorating it.”

“I please myself with imagining a State at last which can afford to be just to all men, and to treat the individual with respect as a neighbor.”

“While the Governor, and the Mayor, and countless officers of the Commonwealth are at large, the champions of liberty are imprisoned.”

“Reverence for life affords me my fundamental principle of morality.”

“Enthusiasm is always connected with the senses, whatever be the object that excites it. The true strength of virtue is serenity of mind, combined with a deliberate and steadfast determination to execute her laws. That is the healthful condition of the moral life; on the other hand, enthusiasm, even when excited by representations of goodness, is a brilliant but feverish glow which leaves only exhaustion and languor behind.”

“Good profits simply are not inconsistent with good behavior.”

“There are no creeds in mathematics.”

“I assert that, in any particular natural science, one encounters genuine scientific substance only to the extent that mathematics is present.”

“No human investigation can claim to be scientific if it doesn't pass the test of mathematical proof.”
