 About a decade after the end of the Second World War the floodgates opened and a stream of work in the analytic mode appeared; the following is merely a sample. D. J. O’Connor published An Introduction to Philosophy of Education (1957) in which, among other things, he argued that the word “theory” as it is used in educational contexts is merely a courtesy title, for educational theories are nothing like what bear this title in the natural sciences. Israel Scheffler, who became the paramount philosopher of education in North America, produced a number of important works including The Language of Education (1960), which contained clarifying and influential analyses of definitions (he distinguished reportive, stipulative, and programmatic types) and the logic of slogans (often these are literally meaningless, and, he argued, should be seen as truncated arguments), Conditions of Knowledge (1965), still the best introduction to the epistemological side of philosophy of education, and Reason and Teaching (1973 [1989]), which in a wide-ranging and influential series of essays makes the case for regarding the fostering of rationality/critical thinking as a fundamental educational ideal (cf. Siegel 2016). B. O. Smith and R. H. Ennis edited the volume Language and Concepts in Education (1961); and R.D. Archambault edited Philosophical Analysis and Education (1965), consisting of essays by a number of prominent British writers, most notably R. S. Peters (whose status in Britain paralleled that of Scheffler in the United States), Paul Hirst, and John Wilson. Topics covered in the Archambault volume were typical of those that became the “bread and butter” of analytic philosophy of education (APE) throughout the English-speaking world—education as a process of initiation, liberal education, the nature of knowledge, types of teaching, and instruction versus indoctrination.
