This article seeks to demonstrate a particular application of Foucault's philosophical approach to a particular issue in education: that of personal autonomy. The paper surveys and extends the approach taken by James Marshall in his book "Michel Foucault: Personal Autonomy and Education." After surveying Marshall's writing on the issue I extend Marshall's approach, critically analysing the work of Rob Reich and Meira Levinson, two contemporary philosophers who advocate models of personal autonomy as the basis for a liberal education.
