I think love, both kinds of love, which you remember Plato defines in his "Symposium" - both kinds of love serve a touchstone for men. Some men understand only the one, some only the other. Those who understand only the non-platonic love need not speak of tragedy. For such love there can be no tragedy. "Thank you kindly for the pleasure, good bye," and that's the whole tragedy. And for the platonic love there can be no tragedy either, because there everything is clear and pure.

Leo Tolstoy
