'This is a worthy book which revivifies one of the most tired topics in educational psychology. On its first page, Peter Drucker is quoted thus: 'We know nothing about motivation. All we do is write books about it.' On reaching its final page this has been totally contradicted: by reading this book you will know a good deal about motivation particularly as an antidote for learners in cynical modern educational contexts. With Covington motivation is always a fresh topic.' Tom Phillips, Vocational Aspect of Education
