but we must observe the distinctions so far as it is practicable to do so.

A question is also raised as to the propriety of dissolving or not dissolving those Friendships the parties to which do not remain what they were when the connection was formed.
1165b Now surely in respect of those whose motive to Friendship is utility or pleasure there can be nothing wrong in breaking up the connection when they no longer have those qualities; because they were friends [not of one another, but] of those qualities: and, these having failed, it is only reasonable to expect that they should cease to entertain the sentiment.
But a man has reason to find fault if the other party, being really attached to him because of advantage or pleasure, pretended to be so because of his moral character: in fact, as we said at the commencement, the most common source of quarrels between friends is their not being friends on the same grounds as they suppose themselves to be.
Now when a man has been deceived in having supposed himself to excite the sentiment of Friendship by reason of his moral character, the other party doing nothing to indicate he has but himself to blame: but when he has been deceived by the pretence of the other he has a right to find fault with the man who has so deceived him, aye even more than with utterers of false coin, in proportion to the greater preciousness of that which is the object-matter of the villany.
But suppose a man takes up another as being a good man, who turns out, and is found by him, to be a scoundrel, is he bound still to entertain Friendship for him? or may we not say at once it is impossible? since it is not everything which is the object-matter of Friendship, but only that which is good; and so there is no obligation to be a bad man's friend, nor, in fact, ought one to be such: for one ought not to be a lover of evil, nor to be assimilated to what is base; which would be implied, because we have said before, like is friendly to like.
Are we then to break with him instantly? not in all cases;
