Amoeba has her picture in the book, Proud Protozoon!-Yet beware of pride, All she can do is fatten and divide; She cannot even read, or sew, or cook... The Worm can crawl But has no eyes to look. The Jelly-fish can swim But lacks a bride.

God is one among several hypotheses to account for the phenomena of human destiny, and it is now proving to be an inadequate hypothesis. To a great many people, including myself, this realization is a great relief, both intellectually and morally. It frees us to explore the real phenomena for which the God hypothesis seeks to account, to define them more accurately, and to work for a more satisfying set of concepts.

The proof given by Wright, that non-adaptive differentiation will occur in small populations owing to "drift," or the chance fixation of some new mutation or recombination, is one of the most important results of mathematical analysis applied to the facts of neo-mendelism. It gives accident as well as adaptation a place in evolution, and at one stroke explains many facts which puzzled earlier selectionists, notably the much greater degree of divergence shown by island than mainland forms, by forms in isolated lakes than in continuous river-systems.

The sense of spiritual relief which comes from rejecting the idea of God as a supernatural being is enormous.

...it is curiosity, initiative, originality, and the ruthless application of honesty that count in research- much more than feats of logic and memory alone.

To speculate without facts is to attempt to enter a house of which one has not the key, by wandering aimlessly round and round, searching the walls and now and then peeping through the windows. Facts are the key.

...everything in psychosocial evolution which can properly be called advance, or progress, or improvement, is due directionaly to the increase or improvement of knowledge.
