According to Greek mythology, humans were originally created with four arms, four legs and a head with two faces. Fearing their power, Zeus split them into two separate parts, condemning them to spend their lives in search of their other halves.
PlatoMathematics is like draughts in being suitable for the young, not too difficult, amusing, and without peril to the state.
Plato... our purpose in founding our state was not to promote the happiness of a single class, but, so far as possible, of the whole community. Our idea was that we were most likely to justice in such a community, and so be able to decide the question we are trying to answer. We are therefore at the moment trying to construct what we think is a happy community by securing the happiness not of a select minority, but of a whole.
