331. Uses for sustaining the body relate to its nourishment, its clothing, its habitation, its recreation and enjoyment, its protection and the preservation of its state. The uses created for the nourishment of the body are all things of the vegetable kingdom suitable for food and drink, as fruits, grapes, grain, pulse, and herbs; in the animal kingdom all things which are eaten, as oxen, cows, calves, deer, sheep, kids, goats, lambs, and the milk they yield; also fowls and fish of many kinds. The uses created for the clothing of the body are many other products of these two kingdoms; in like manner, the uses for habitation, also for recreation, enjoyment, protection, and preservation of state. These are not mentioned because they are well known, and their mere enumeration would fill pages. There are many things, to be sure, which are not used by man; but what is superfluous does not do away with the use, but ensures its continuance. Misuse of uses is also possible, but misuse does not do away with use, even as falsification of truth does not do away with truth except with those who falsify it.
