Philosophy of Education is a discipline that arose historically in the context of the endeavor to turn education into an object of scientific, rigorous knowledge. The main question that it should address is thus not “What is philosophy?” but rather, “What is education?” When the start is the first question, the discourse tends to focus too narrowly in on itself, on the problems of philosophers. The second question was the starting point for the movement that has done the most to consolidate this form of knowledge: the school promoted by R.S. Peters and his followers.
