Plato’s Laws (Nomoi) is among his works the best for the understanding not only of Plato’s reflections upon education, performance, and music etc., but also of the aims of physical education from the perspectives of sports and gender. Plato argues that the law should help to keep the good condition and balance not only in society and polis but also in body and mind (soul). The means of keeping and promoting the good condition is not only the enforcement and punishment but rather the control of one’s emotion by allowing pleasure (hedone in Greek). Education is the best way of controlling the emotion. The one of two ways of education is gymnastike in Greek and the other is mousike in Greek (music in wider sense). In this paper the auther argues that the teaching and research of sports and gender lies in the same line with Plato’s idea of education.
