Strangely, the concept of philosophical education is not much in use, at least not as a "philosophical" concept. In this essay, Steinar Boyum attempts to outline such a philosophical concept of philosophical education. Boyum uses Plato's Allegory of the Cave, Rene Descartes's life of doubt, and Immanuel Kant's criticism of metaphysics as paradigms or defining examples of this concept. Boyum's aim in this essay is not exegetical; rather, he hopes to describe these examples in a way that will let their character as conceptions of philosophical education show forth. His underlying aims are to show which forms such conceptions may take and why philosophical education is or should be an important topic for both philosophy and education.
