George Gaylord Simpson Quotes

The question “What is man?” is probably the most profound that can be asked by man. It has always been central to any system of philosophy or theology…. The point I want to make now is that all attempts to answer that question before 1859 are worthless and that we will be better off if we ignore them completely.

~ George Gaylord Simpson

If I didn't fear I'd do you harm...I'd try to make you an atheist. I really do think that you are a deluded follower of mistaken and superstitious and cowardly theories. That's as far as I'll go....Everyone who worships a god worships a force back of all nature, no matter what they call him or it and even if they call his aspects by different names & have many gods. If there really is such a force, then all people who worship any god or gods, worship the same god. I'd just as soon call him Ishtar or Baal or Jehovah. They're merely names for the same idea. (Letter from Simpson to Anne Roe, written ca. 1920-21, when Anne was briefly flirting with fundamentalist Christianity, American Philosophical Society archives.)

~ George Gaylord Simpson

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

~ George Gaylord Simpson

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.

~ George Gaylord Simpson

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.

~ George Gaylord Simpson

If a sect does officially insist that its structure of belief demands that evolution be false, then no compromise is possible. An honest and competent biology teacher can only conclude that the sect's beliefs are wrong and that its religion is a false one.

~ George Gaylord Simpson

Species evolve exactly as if they were adapting as best they could to a changing world, and not at all as if they were moving toward a set goal.

~ George Gaylord Simpson

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.

~ George Gaylord Simpson

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.
