Plato Lysis 212

Accordingly, when I see you and Lysis together, I am quite beside myself, and congratulate you on being able, at such an early age, to gain this possession so quickly and easily; since you, Menexenus, have so quickly and surely acquired his friendship, and he likewise yours: whereas I am so far from acquiring such a thing, that I do not even know in what way one person becomes a friend of another, and am constrained to ask you about this very point, in view of your experience.
  Now tell me: when one person loves another, which of the two becomes friend of the other— 212b the loving of the loved, or the loved of the loving? Or is there no difference? There is none, he replied, in my opinion. How is that? I said; do you mean that both become friends mutually, when there is only one loving the other? Yes, I think so, he replied. But I ask you, is it not possible for one loving not to be loved by him whom he loves? It is. But again, may he not be even hated while loving? This, I imagine, is the sort of thing that lovers do sometimes seem to incur with their favorites: 212c they love them with all their might, yet they feel either that they are not loved in return, or that they are actually hated. Or do you not think this is true? Very true, he replied. Now in such a case, I went on, the one loves and the other is loved? Yes. Which of the two, then, is a friend of the other? Is the loving a friend of the loved, whether in fact he is loved in return or is even hated, or is the loved a friend of the loving? Or again, is neither of them in such a case friend of the other, if both do not love mutually? 212d At any rate, he said, it looks as if this were so. So you see, we now hold a different view from what we held before. At first we said that if one of them loved, both were friends: but now, if both do not love, neither is a friend. It looks like it, he said. So there is no such thing as a friend for the lover who is not loved in return. Apparently not. And so we find no horse-lovers where the horses do not love in return, no quail-lovers, dog-lovers, wine-lovers, or sport-lovers on such terms, nor any lovers of wisdom if she returns not their love. Or does each person love these things, 212e while yet failing to make friends of them, and was it a lying poet who said— Solon 21.2. I do not think so, he said. But do you think he spoke the truth? Yes.
