One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.
Nature is beautiful because it looks like Art; and Art can only be called beautiful if we are conscious of it as Art while yet it looks like Nature.[Die Natur war schön, wenn sie zugleich als Kunst aussah; und die Kunst kann nur schön genannt werden, wenn wir uns bewußt sind, sie sei Kunst, und sie uns doch als Natur aussieht.]

Whatsoever is contrary to nature is also contrary to reason, and whatsoever is contrary to reason is absurd.
