331. Useful functions for the support of our bodies have to do with its nourishment, clothing, shelter, recreation and pleasure, protection, and the preservation of its state. The useful things created for physical nourishment are all the members of the plant kingdom that we eat and drink, such as fruits, grapes, seeds, vegetables, and grains. Then there are all the members of the animal kingdom that we eat, such as steers, cows, calves, deer, sheep, kids, goats, lambs, and the milk they give, as well as many kinds of bird and fish.
The useful things created for clothing our bodies also come in abundance from these two kingdoms, as do those for our shelter and for our recreation and pleasure, for our protection, and for the preservation of our state. I will not enumerate these because they are familiar, so listing them would only take up space.
There are of course many things that we do not find useful, but these extras do not prevent usefulness. In fact, they enable useful functions to continue. Then there are abuses of functions; but again, the abuse of a function does not eliminate the useful function, just as the falsification of something true does not destroy the truth except for the people who are doing the falsifying.
