柏拉图在其著作《酒宴》中借阿里斯托芬之口讲过这样一个神话。他说,从前,人类有三种人:男、女、和一种怪诞的第三种人。这种人的形体是圆的,犹如一只封闭的球,有4只手,4条腿和两种生殖器。后来,由于诸神对这种人极为憎厌,于是,将他们一刀劈为两半放逐到人世中去了。 Plato spoke of such a myth by Aristophanes in his book The Banquet. He said that in the past, there were three kinds of human beings: men and women, and a weird third person. This human figure is round, like a closed ball with 4 hands, 4 legs and two genitals. Later, because the gods were extremely abhorrent to such people, they were banished into men’s world by a knife and a knife.
