Foucault's theory about discipline indicates that rules and regulations in education management may lead to soul manipulation, which shows the correlation between ideological and political education and discipline. However, people regard ideological and political education as discipline because of the misunderstanding of the nature of discipline. The essence of discipline is oppressive power. It is originated from the production link of capitalism and may be surmounted with the sublation of capitalism. Ideological and political education is not discipline and as the political practice of ideology, it can only transcend discipline and find its foundation from the perspective of Marx's critique of capitalism.
