Nicomachean Ethics

Kindly Feeling, though resembling Friendship, is not identical with it, because it may exist in reference to those whom we do not know and without the object of it being aware of its existence, which Friendship cannot. (This, by the way, has also been said before.) And further, it is not even Affection because it does not imply intensity nor yearning, which are both consequences of Affection. Again Affection requires intimacy but Kindly Feeling may arise quite suddenly, as happens sometimes in respect of men against whom people are matched in any way, I mean they come to be kindly disposed to them and sympathise in their wishes, but still they would not join them in any action, because, as we said, they conceive this feeling of kindness suddenly and so have but a superficial liking.

What it does seem to be is the starting point of a Friendship; just as pleasure, received through the sight, is the commencement of Love: for no one falls in love without being first pleased with the personal appearance of the beloved object, and yet he who takes pleasure in it does not therefore necessarily love, but when he wearies for the object in its absence and desires its presence. Exactly in the same way men cannot be friends without having passed through the stage of Kindly Feeling, and yet they who are in that stage do not necessarily advance to Friendship: they merely have an inert wish for the good of those toward whom they entertain the feeling, but would not join them in any action, nor put themselves out of the way for them. So that, in a metaphorical way of speaking, one might say that it is dormant Friendship, and when it has endured for a space and ripened into intimacy comes to be real Friendship; but not that whose object is advantage or pleasure, because such motives cannot produce even Kindly Feeling.

I mean, he who has received a kindness requites it by Kindly Feeling towards his benefactor, and is right in so doing: but he who wishes another to be prosperous, because he has hope of advantage through his instrumentality, does not seem to be kindly disposed to that person but rather to himself; just as neither is he his friend if he pays court to him for any interested purpose.

Kindly Feeling always arises by reason of goodness and a certain amiability, when one man gives another the notion of being a fine fellow, or brave man, etc., as we said was the case sometimes with those matched against one another.
