Then, even if evil perishes, there may still remain some elements of love or friendship?
Yes.
But not if evil is the cause of friendship: for in that case nothing will be the friend of any other thing after the destruction of evil; for the effect cannot remain when the cause is destroyed.
True.
And have we not admitted already that the friend loves something for a reason? and at the time of making the admission we were of opinion that the neither good nor evil loves the good because of the evil?
Very true.
But now our view is changed, and we conceive that there must be some other cause of friendship?
I suppose so.
May not the truth be rather, as we were saying just now, that desire is the cause of friendship; for that which desires is dear to that which is desired at the time of desiring it? and may not the other theory have been only a long story about nothing?
Likely enough.
But surely, I said, he who desires, desires that of which he is in want?
Yes.
And that of which he is in want is dear to him?
True.
And he is in want of that of which he is deprived?
Certainly.
Then love, and desire, and friendship would appear to be of the natural or congenial. Such, Lysis and Menexenus, is the inference.
They assented.
Then if you are friends, you must have natures which are congenial to one another?
Certainly, they both said.
And I say, my boys, that no one who loves or desires another would ever have loved or desired or affected him, if he had not been in some way congenial to him, either in his soul, or in his character, or in his manners, or in his form.
