Book excerpt: When originally published in 1965 this book reflected some of the new thinking among philosophers regarding the role of the discipline in its investigation of central issues in educaton. The essays are grouped into four major sections: The Nature and Function of Educational Theory; The Context of Educational Discussion; Conceptions of Teaching; and The Essence of Education. The concepts dealt with are of the first importance to any practical or theoretical discussion in education and the editor provides a generous introduction to the essays to aid the reader in his analysis of the issues.
