“A man wholly destitute of philanthropy is a monster, justly detested by all mankind; but another, entirely incapable of anger, is a sheepish wretch, liable to be insulted by every mean-spirited villain.”

Durch die Künstler wird die Menschheit ein Individuum, indem sie Vor welt und Nachwelt in der Gegenwart verknüpfen. Sie sind das höhere Seelenorgan, wo die Lebensgeister der ganzen 15 äussern Menschheit zusammentreffen und in welchem die innere zunächst wirkt.

The Farmer Refuted (1775)
Context: The origin of all civil government, justly established, must be a voluntary compact, between the rulers and the ruled; and must be liable to such limitations, as are necessary for the security of the absolute rights of the latter; for what original title can any man or set of men have, to govern others, except their own consent? To usurp dominion over a people, in their own despite, or to grasp at a more extensive power than they are willing to entrust, is to violate that law of nature, which gives every man a right to his personal liberty; and can, therefore, confer no obligation to obedience.

L'homme enfin n'est pas entièrement coupable — il n'a pas commencé l'histoire — ni tout à fait innocent, puisqu'il la continue.

Context: This freedom of communication is indispensable for the development and extension of scientific knowledge, a consideration of much practical import. In the first instance it must be guaranteed by law. But laws alone cannot secure freedom of expression; in order that every man may present his views without penalty there must be a spirit of tolerance in the entire population. Such an ideal of external liberty can never be fully attained but must be sought unremittingly if scientific thought, and philosophical and creative thinking in general, are to be advanced as far as possible.
