If there be any law truly natural, that is to say, any instinct that is seen universally and perpetually imprinted in both beasts and men (which is not without controversy), I can say, that in my opinion, next to the care every animal has of its own preservation, and to avoid that which may hurt him, the affection that the begetter bears to his offspring holds the second place in this rank. And seeing that nature appears to have recommended it to us, having regard to the extension and progression of the successive pieces of this machine of hers, 'tis no wonder if, on the contrary, that of children towards their parents is not so great. To which we may add this other Aristotelian consideration, that he who confers a benefit on any one, loves him better than he is beloved by him again: that he to whom is owing, loves better than he who owes; and that every artificer is fonder of his work, than, if that work had sense, it would be of him; by reason that it is dear to us to be, and to be consists in movement and action; therefore every one has in some sort a being in his work. He who confers a benefit exercises a fine and honest action; he who receives it exercises the useful only. Now the useful is much less lovable than the honest; the honest is stable and permanent, supplying him who has done it with a continual gratification. The useful loses itself, easily slides away, and the memory of it is neither so fresh nor so pleasing. Those things are dearest to us that have cost us most, and giving is more chargeable than receiving.
