And this particular obligation
I have to this treatise of his, that it was the occasion of my first
coming acquainted with him; for it was showed to me long before I had the
good fortune to know him; and the first knowledge of his name, proving
the first cause and foundation of a friendship, which we afterwards
improved and maintained, so long as God was pleased to continue us
together, so perfect, inviolate, and entire, that certainly the like is
hardly to be found in story, and amongst the men of this age, there is no
sign nor trace of any such thing in use; so much concurrence is required
to the building of such a one, that 'tis much, if fortune bring it but
once to pass in three ages.

There is nothing to which nature seems so much to have inclined us, as to
society; and Aristotle , says that the good legislators had more respect
to friendship than to justice. Now the most supreme point of its
perfection is this: for, generally, all those that pleasure, profit,
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
