Paraphrasing Ludwig Wittgenstein, who asserts that "Philosophy is not a theory, but an activity," we might say that philosophy of education is not a theory, but a pedagogical activity. From the classic philosophers of education, such as Confucius, Socrates, and Plato, through Rousseau, Aquinas, and many more who lead up to the modern age of such thinkers as Dewey, Sartre, Arendt, and Chomsky, this comprehensive introduction to the most important branches and representatives of the philosophy of education spans the personalities, terminology and vocabulary of thousands of years of philosophical thought in addition to the more recent encroachment of social and psychological sciences.
