Now, the good man has the same relation to his friend as he has to himself; for a friend is another self; in the same manner, therefore, as to exist one’s self is eligible to every one, so also is it for one’s friend to exist, or nearly so. But existence was said to be eligible on account of the perception of that which is a good: and such a perception is pleasant in itself. We ought, therefore, to be conscious of the existence of our friend; and this would result from associating with him, and sharing his words and thoughts; for this would seem to be the meaning of the word society, when applied to men, and not, as in the case of cattle, the merely feeding in the existence. If, then, existence is in itself eligible to the happy man, being by nature something good and pleasant, and if the existence of a friend is nearly the same, then a friend must also be of the number of eligible things. But that which is eligible to a man, he ought to possess; or else he is deficient in that respect; he, therefore, that is to be happy will need good friends.
It is pleasant to be loved, for this makes a man see himself as the possessor of goodness, a thing that every being that has a feeling for it desires to possess: to be loved means to be valued for one’s own personal qualities.
