There are then three causes from which men feel Friendship: but the term is not applied to the case of fondness for things inanimate because there is no requital of the affection nor desire for the good of those objects: it certainly savours of the ridiculous to say that a man fond of wine wishes well to it: the only sense in which it is true being that he wishes it to be kept safe and sound for his own use and benefit.204 But to the friend they say one should wish all good for his sake. And when men do thus wish good to another (he not reciprocating the feeling), people call them Kindly; because Friendship they describe as being “Kindliness between persons who reciprocate it.” But must they not add that the feeling must be mutually known? for many men are kindly disposed towards those whom they have never seen but whom they conceive to be amiable or useful: and this notion amounts to the same thing as a real feeling between them.
Well, these are plainly Kindly-disposed towards one another: but how can one call them friends while their mutual feelings are unknown to one another? to complete the idea of Friendship, then, it is requisite that they have kindly feelings towards one another, and wish one another good from one of the aforementioned causes, and that these kindly feelings should be mutually known.
Chapter IV.
As the motives to Friendship differ in kind so do the respective feelings and Friendships. The species then of Friendship are three, in number equal to the objects of it, since in the line of each there may be “mutual affection mutually known.”
Now they who have Friendship for one another desire one another’s good according to the motive of their Friendship; accordingly they whose motive is utility have no Friendship for one another really, but only in so far as some good arises to them from one another.
