Note 1 — ON THE CONNECTION BETWEEN THE ANIMAL AND THE SPIRITUAL NATURE IN MAN.

Huxley, speaking of psychology and physiology (idealism and materialism), says: "Our stem divides into two main branches, which grow in opposite ways, and bear flowers which look as different as they can well be. But each branch is sound and healthy, and has as much life and vigor as the other. If a botanist found this state of things in a new plant, I imagine he might be inclined to think that his tree was monoecious, that the flowers were of different sexes, and that, so far from setting up a barrier between the branches of the tree, the only hope of fertility lay in bringing them together. This is my notion of what is to be done with physics and metaphysics. Their differences are complementary, not antagonistic, and thought will never be completely fruitful until the one unites with the other."—HUXLEY, Macmillan's Mag., May 1870.
