Book IV chapter 18

A proof that gratitude¹ is desirable for itself lies in the fact that ingratitude² is to be avoided for itself, because no vice³ more powerfully rends⁴ asunder⁶ and destroys the union of the human race. To what do we trust for safety, if not in mutual⁷ good offices one to another? It is by the interchange of benefits alone that we gain some measure of protection for our lives, and of safety against sudden disasters. Taken singly, what should we be? a prey⁸ and quarry⁹ for wild beasts, a luscious¹⁰ and easy banquet; for while all other animals have sufficient strength to protect themselves, and those which are born to a wandering solitary¹¹ life are armed, man is covered by a soft skin, has no powerful teeth or claws with which to terrify other creatures, but weak and naked by himself is made strong by union.

God has bestowed¹² upon him two gifts, reason and union, which raise him from weakness to the highest power; and so he, who if taken alone would be inferior to every other creature, possesses supreme¹³ dominion¹⁴. union has given him sovereignty over all animals; union has enabled a being born upon the earth to assume power over a foreign element, and bids him be lord of the sea also; it is union which has checked the inroads of disease, provided supports for our old age, and given us relief from pain; it is union which makes us strong, and to which we look for protection against the caprices of fortune. Take away union, and you will rend⁵ asunder the association by which the human race preserves its existence; yet you will take it away if you succeed in proving that ingratitude is not to be avoided for itself, but because something is to be feared for it; for how many are there who can with safety be ungrateful? In fine, I call every man ungrateful who is merely made grateful by fear.
