As the proverb says: “Where small means suffice, great should not be used.”
12. Let us choose the sun for imitation, since it affords a striking example of the operations of nature. Its functions are laborious and almost unlimited (namely, to send forth its rays over the whole world and to supply all the elements, minerals, plants, and animals, of which countless species exist, with light, warmth, life, and strength), but it proves equal to them all, and every year fulfils the circle of its duties in the most admirable manner.
