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.

Quantity of material production can only be a means to a further end, not an end in itself.

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.

Sir Julian Huxley, one of the world's leading evolutionists, head of UNESCO, descendant of Thomas Huxley - Darwin's bulldog - said on a talk show, 'I suppose the reason we leaped at The Origin of Species was because the idea of God interfered with our sexual mores.'.

The god hypothesis is no longer of any pragmatic value for the interpretation or comprehension of nature, and indeed often stands in the way of better and truer interpretation. Operationally, God is beginning to resemble not a ruler, but the last fading smile of a cosmic Cheshire Cat.
