George Gaylord Simpson Quotes

The conflict between science and religion has a single and simple cause. It is the designation as religiously canonical of any conception of the material world open to scientific investigation....As a matter of fact, most of the dogmatic religions have exhibited a perverse talent for taking the wrong side on the most important concepts of the material universe, from the structure of the solar system to the origin of man. The result has been constant turmoil for many centuries, and the turmoil will continue as long as religious canons prejudge scientific questions.

From horses we may learn not only about the horse itself but also about animals in general, indeed about ourselves and about life as a whole.

Man is the result of a purposeless and natural process that did not have him in mind.

To put it crudely but graphically, the monkey who did not have a realistic perception of the tree branch he jumped for was soon a dead monkey—and therefore did not become one of our ancestors.

Among the things most characteristic of organisms--most distinctive of living as opposed to inorganic systems--is a sort of directedness. Their structures and activities have an adaptedness, an evident and vital usefulness to the organism. Darwin's answer and ours is to accept the common sense view...[that] the end ("telos") [is] that the individual and the species may survive. But this end is (usually) unconscious and impersonal. Naive teleology is controverted not by ignoring the obvious existence of such ends but by providing a naturalistic, materialistic explanation of the adaptive characteristics serving them. [Book review in "Science," 1959, p. 673.]

I don't think that evolution is supremely important because it is my specialty; it is my specialty because I think it is supremely important. [In: Edward J. Larson (2004) Evolution, Modern Library. p. 250]

The greatest impact of the Darwinian revolution...was that it completed the liberation from superstition and fear that began in the physical sciences a few centuries before. Man, too, is a natural phenomenon. [in "The evolutionary concept of man", 1972, p. 35.]

Man has risen, not fallen. He can choose to develop his capacities as the highest animal and to try to rise still farther, or he can choose otherwise. The choice is his responsibility, and his alone. There is no automatism that will carry him upward without choice or effort and there is no trend solely in the right direction. Evolution has no purpose; man must supply this for himself. The means to gaining right ends involve both organic evolution and human evolution, but human choice as to what are the right ends must be based on human evolution.
