Of God and His Creatures"True, in the individual, plant or animal, there are many potentialities frustrate and made void. That is neither here nor there in philosophy. Philosophy deals not with individuals but with species; not with Bucephalus or Alexander, but with horse, man. Enough that one seed ever germinates, and that all normal specimens are apt to do the like, meeting with proper environment." -- Ethics and Natural Law, p. 17.
