power of self-direction, but is governed by two main instincts, which keep his powers on the alert, impel him to develop them in a fitting manner, and stimulate and determine him to action without any power of choice. One of these instincts is self-preservation, the other the propagation of the species. Both can attain their purpose by means of things which lie within range; beyond their verge the brute creation cannot go, for they are moved to action by their senses only, and in the special direction which these suggest. But with man it is wholly different. He possesses, on the one hand, the full perfection of the animal being, and hence enjoys, at least as much as the rest of the animal kind, the fruition of things material. But animal nature, however perfect, is far from representing the human being in its completeness, and is in truth but humanity's humble handmaid, made to serve and to obey. It is the mind, or reason, which is the predominant element in us who are human creatures; it is this which renders a human being human, and distinguishes him essentially and generically from the brute. And on this very account — that man alone among the animal creation is endowed with reason — it must be within his right to possess things not merely for temporary and momentary use, as other living things do, but to have and to hold them in stable and permanent possession; he must have not only things that perish in the use of them, but those also which, though they have been reduced into use, remain his own for further use.
This becomes still more clearly evident if man's nature be considered a little more deeply. For man, fathoming by his faculty of reason matters without number, and linking the future with the present, becoming, furthermore, by taking enlightened forethought, master of his own acts, guides his ways under the eternal law and the power of God, whose providence governs all things. Wherefore it is in his power to exercise his choice not only as to matters that regard his present welfare, but also about those which he
