“Any concept of biology is not only sterile and profitless, it is distorted and untrue, if it puts its primary focus on unnatural conditions rather than on those vast forces not of man's making that shape and channel the nature and direction of life.”
Preface to Humane Biology Projects (1961) by the Animal Welfare Institute

Context: Conformity to nature has no connection whatever with right and wrong. The idea can never be fitly introduced into ethical discussions at all, except, occasionally and partially, into the question of degrees of culpability. To illustrate this point, let us consider the phrase by which the greatest intensity of condemnatory feeling is conveyed in connection with the idea of nature - the word "unnatural." That a thing is unnatural, in any precise meaning which can be attached to the word, is no argument for its being blamable; since the most criminal actions are to a being like man not more unnatural than most of the virtues.

VIII. On Mind and Soul, and that the latter is immortal.
On the Gods and the Cosmos
Context: There is a certain force, less primary than being but more primary than the soul, which draws its existence from being and completes the soul as the sun completes the eyes. Of souls some are rational and immortal, some irrational and mortal. The former are derived from the first Gods, the latter from the secondary.
