public or private interest create and nourish, are so much the less
beautiful and generous, and so much the less friendships, by how much
they mix another cause, and design, and fruit in friendship, than itself.
Neither do the four ancient kinds, natural, social, hospitable, venereal,
either separately or jointly, make up a true and perfect friendship.

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
