To give a logical ground for such a selection is evidently impossible, since it is logic itself that is to be accounted for. A natural ground is, in strictness, also irrelevant, since natural connections, where thought has not reduced them to a sort of equivalence and necessity, are mere data and juxtapositions. Yet it is not necessary to leave the question altogether unanswered. By using our senses we may discover, not indeed why each sense has its specific quality or exists at all, but what are its organs and occasions. In like manner we may, by developing the Life of Reason, come to understand its conditions. When consciousness awakes the body has, as we long afterward discover, a definite organisation. Without guidance from reflection bodily processes have been going on, and most precise affinities and reactions have been set up between its organs and the surrounding objects. On these affinities and reactions sense and intellect are grafted. The plants are of different nature, yet growing together they bear excellent fruit. It is as the organs receive appropriate stimulations that attention is riveted on definite sensations. It is as the system exercises its natural activities that passion, will, and meditation possess the mind. No syllogism is needed to persuade us to eat, no prophecy of happiness to teach us to love. On the contrary, the living organism, caught in the act, informs us how to reason and what to enjoy. The soul adopts the body’s aims; from the body and from its instincts she draws a first hint of the right means to those accepted purposes. Thus reason enters into partnership with the world and begins to be respected there; which it would never be if it were not expressive of the same mechanical forces that are to preside over events and render them fortunate or unfortunate for human interests. Reason is significant in action only because it has begun by taking, so to speak, the body’s side; that sympathetic bias enables her to distinguish events pertinent to the chosen interests, to compare impulse with satisfaction, and, by representing a new and circular current in the system, to preside over the formation of better habits, habits expressing more instincts at once and responding to more opportunities.
