331. Forms of use for sustaining the body relate to its nourishment, clothing, lodging, recreation and enjoyment, and protection, and the preservation of its condition. Forms of use created for the nourishment of the body are all constituents of the plant kingdom which are serviceable for food and drink, such as fruits, grapes, seeds, vegetables and herbs. So, too, all constituents of the animal kingdom which are eaten, such as steers, cows, calves, deer, sheep, male and female goats, lambs, and the milk obtained from them. And also fowl and fish of many kinds. Forms of use created for the clothing of the body are likewise many of the constituents of these two kingdoms. So, too, forms of use for its lodging; and also for its recreation, enjoyment, and protection, and the preservation of its condition-instances of which we do not enumerate because they are well known, and listing them, therefore, would only serve to fill pages. There are, indeed, many of these forms which do not result in anything useful to mankind, but their superfluousness does not take away their usefulness, but ensures that forms of use continue. Possible also are abuses of forms of use, but the abuse does not take away their usefulness, just as falsifying a truth does not do away with the truth, other than in the people who do it.
