Throughout the course of his career Lionel Elvin has worked closely with experts in many different areas of the educational field and has found that in coming to conclusions about either theory or practical policy, commonsense is indispensable. The author explores the idea of commonsense in education in this study, first published in 1977, and examines this theme both in general and particular terms of the concepts people invoke in educational discussion. This title will be of interest to students of the philosophy of education.
