Next would seem properly to follow a dissertation on Friendship:
because, in the first place, it is either itself a virtue or connected
with virtue; and next it is a thing most necessary for life, since no
one would choose to live without friends though he should have all the
other good things in the world: and, in fact, men who are rich or
possessed of authority and influence are thought to have special need
of friends: for where is the use of such prosperity if there be taken
away the doing of kindnesses of which friends are the most usual and
most commendable objects? Or how can it be kept or preserved without
friends? because the greater it is so much the more slippery and
hazardous: in poverty moreover and all other adversities men think
friends to be their only refuge.
Furthermore, Friendship helps the young to keep from error: the old, in
respect of attention and such deficiencies in action as their weakness
makes them liable to; and those who are in their prime, in respect of
noble deeds (“They _two_ together going,” Homer says, you may
remember), because they are thus more able to devise plans and carry
them out.
Again, it seems to be implanted in us by Nature: as, for instance, in
the parent towards the offspring and the offspring towards the parent
(not merely in the human species, but likewise in birds and most
animals), and in those of the same tribe towards one another, and
specially in men of the same nation; for which reason we commend those
men who love their fellows: and one may see in the course of travel how
close of kin and how friendly man is to man.
Furthermore, Friendship seems to be the bond of Social Communities, and
legislators seem to be more anxious to secure it than Justice even. I
mean, Unanimity is somewhat like to Friendship, and this they certainly
aim at and specially drive out faction as being inimical.
Again, where people are in Friendship Justice is not required;[1] but,
on the other hand, though they are just they need Friendship in
addition, and that principle which is most truly just is thought to
partake of the nature of Friendship.
Lastly, not only is it a thing necessary but honourable likewise: since
we praise those who are fond of friends, and the having numerous
friends is thought a matter of credit to a man; some go so far as to
hold, that “good man” and “friend” are terms synonymous.
Chapter II.
Yet the disputed points respecting it are not few: some men lay down
that it is a kind of resemblance, and that men who are like one another
are friends: whence come the common sayings, “Like will to like,”
“Birds of a feather,” and so on. Others, on the contrary, say, that all
such come under the maxim, “Two of a trade never agree.”[2]
Again, some men push their enquiries on these points higher and reason
physically: as Euripides, who says,
“The earth by drought consumed doth love the rain,
And the great heaven, overcharged with rain,
Doth love to fall in showers upon the earth.”
