Identifying the beautiful and the favourable leads to a paradox: the favourable procreates the beautiful, as a father procreates a son. Since the favourable and the beautiful are thus considered to be one and the same, they arrive at the finding that beauty is the reason of goodness. In logic, a cause and an effect are two different things, as a father is different from the son. And thus they must conclude that Beauty is not good, and good is not beauty; an assertion which pleases neither Socrates nor Hippias.
