First published in 1967, this book suggests that educational problems should not, and indeed cannot, be solved in isolation, but that we need to bring all our disciplines and resources to bear upon them. It explores in turn philosophical, psychological and sociological approaches to educational theory and examines great thinkers such as Plato, Rousseau, Freud, Piaget, Durkheim and Mannheim. In doing so, it argues that answers to educational problems lie in a multi-disciplined and integrated approach.
