One influential line of argument was developed by Paul Hirst, who argued that knowledge is essential for developing and then pursuing a conception of the good life, and because logical analysis shows, he argued, that there are seven basic forms of knowledge, the case can be made that the function of the curriculum is to introduce students to each of these forms (Hirst 1965; see Phillips 1987: ch. 11).
