The justification of liberal education
Justifications for any kind of instrumental education will be of three kinds: firstly, the justification of the end to which the instrumentality is directed; secondly, a demonstration of the efficiency or effectiveness of the proposed education in preparing people for the justified activity, profession or whatever; and thirdly, some consideration of the likelihood of the person being prepared actually ever engaging in the justified activity, profession or whatever it is that he is being prepared for. For example, I justify engaging John Brown in a particular form of medical education if I can show:
(a) the general desirability of practising medicine; (b) that this particular form of education will effectively prepare someone to practise
medicine; and (c) John Brown is likely to practise medicine if successfully medically educated.
