Locke, in his chapter on "Power" (human understanding), seems to draw very near to an admission of Determinism, but then flies away from it, evidently alarmed by the spectre of irresponsibility. He labours to demonstrate that uneasiness or desire determines the will to the successive (so-called) voluntary actions whereof the greatest part of our lives is made up, and by which we are _conducted_ through different causes to different ends. This is, as far as it goes, unadulterated Determinism. Dr. Paul Carus defines freedom of will as the power to do that which one wills, not as the freedom of a man to will what he wills. Indeterminism he declares to be based upon error, because it attributes to man an exceptional place in the universe. Man is supposed to be exempt from the uniform and inexorable law of cause and effect which rules in the universe. He says: "The decision of a free man depends upon his character"; but character is only the result of innumerable causes, which has become a cause upon which other effects follow, according to the cosmic law of causation, which must include in its impartial sway man as well as all other integrations of matter. Determinism is morally safe, because man cannot escape from the _feeling_ that he possesses free-will, which, nevertheless, is an illusion, in the sense that "illusions are ideas that have not originated from the data of experience." In _Light_ (April 18th, 1898) there is quoted the following, as part of a discourse on "The Evolution of Mind," delivered by Professor Jordan: "The plant searches for food by a movement of the feeding parts alone.... The tender tip is the plant's brain. If locomotion were in question, the plant would need to be differently constructed. It would demand the mechanism of the animal. The nerve, brain, and muscle of the plant are all represented by the tender growing cells of the moving tips. The plant is touched by moisture or sunlight. It 'thinks' of them, and in so doing the cells that are touched and 'think' are turned towards the source of the stimulus. The function of the brain, therefore, in some sense exists in the tree, but there is no need in the tree for a special sensorium."
