 Among the most influential products of APE was the analysis developed by Hirst and Peters (1970) and Peters (1973) of the concept of education itself. Using as a touchstone “normal English usage,” it was concluded that a person who has been educated (rather than instructed or indoctrinated) has been (i) changed for the better; (ii) this change has involved the acquisition of knowledge and intellectual skills and the development of understanding; and (iii) the person has come to care for, or be committed to, the domains of knowledge and skill into which he or she has been initiated. The method used by Hirst and Peters comes across clearly in their handling of the analogy with the concept of “reform”, one they sometimes drew upon for expository purposes. A criminal who has been reformed has changed for the better, and has developed a commitment to the new mode of life (if one or other of these conditions does not hold, a speaker of standard English would not say the criminal has been reformed). Clearly the analogy with reform breaks down with respect to the knowledge and understanding conditions. Elsewhere Peters developed the fruitful notion of “education as initiation”.
