That of children to parents is rather respect: friendship is nourished by communication, which cannot by reason of the great disparity, be betwixt these, but would rather perhaps offend the duties of nature; for neither are all the secret thoughts of fathers fit to be communicated to children, lest it beget an indecent familiarity betwixt them; nor can the advices and reproofs, which is one of the principal offices of friendship, be properly performed by the son to the father. There are some countries where ‘twas the custom for children to kill their fathers; and others, where the fathers killed their children, to avoid their being an impediment one to another in life; and naturally the expectations of the one depend upon the ruin of the other. There have been great philosophers who have made nothing of this tie of nature, as Aristippus for one, who being pressed home about the affection he owed to his children, as being come out of him, presently fell to spit, saying, that this also came out of him, and that we also breed worms and lice; and that other, that Plutarch endeavoured to reconcile to his brother: “I make never the more account of him,” said he, “for coming out of the same hole.” This name of brother does indeed carry with it a fine and delectable sound, and for that reason, he and I called one another brothers but the complication of interests, the division of estates, and that the wealth of the one should be the property of the other, strangely relax and weaken the fraternal tie: brothers pursuing their fortune and advancement by the same path, ‘tis hardly possible but they must of necessity often jostle and hinder one another. Besides, why is it necessary that the correspondence of manners, parts, and inclinations, which begets the true and perfect friendships, should always meet in these relations? The father and the son may be of quite contrary humours, and so of brothers: he is my son, he is my brother; but he is passionate, ill-natured, or a fool.
