The universal nature out of the universal substance, as if it were wax, now molds a horse, and when it has broken this up, it uses the material for a tree, then for a man, then for something else; and each of these things subsists for a very short time. But it is no hardship for the vessel to be broken up, just as there was none in its being fastened together.
No man is tired of receiving what is useful. It is useful to act according to nature. Do not then be tired of receiving what is useful by doing what is useful for others.
When you have done a good act and another has received it, why do you look for a third thing besides these, as fools do, either to have the reputation of having done a good act or to obtain a return?
