331. Uses for sustaining the body have reference to its nourishment, clothing, habitation, recreation and enjoyment, protection and preservation of its state. The uses created for the nourishment of the body are all things of the vegetable kingdom which are for eating and drinking, such as fruits, grapes, grain, vegetables and herbs; also all things of the animal kingdom which are eaten, as oxen, cows, calves, deer, sheep, kids, goats, lambs and milk from them, as well as fowls and fish of many kinds. Uses created for the clothing of the body are also many things from these two kingdoms, as also uses for habitation, recreation, enjoyment, protection and preservation of state. These are not enumerated because they are well known, and therefore a mere recounting of them would fill pages. There are indeed many things which yield nothing of use to man, but what is superfluous does not do away with use, but ensures the continuance of use. Abuse of uses is also possible, but abuse does not do away with use, just as falsification of truth does not do away with truth except with those who falsify it.
