On the strength of a clarification of the nature of philosophy of education, a critical overview is offered of Wittgenstein's impact on the field. The focus then narrows to give attention to Wittgenstein's claim that “Nothing is hidden”, pitched here in a questionable relation to contemporary concerns with transparency.

These are argued to be essential to the development of (...) mind and world, from the child's first entry into language, and hence crucial to education. (shrink)
