Abstract

A volume in the International Library of the Philosophy of Education under the general editorship of R. S. Peters, which will both interest and repay close study by epistemologists and philosophers of language, as well as philosophers of education. The book concerns concept formation and the growth of knowledge, i.e., as the general editor of the series writes, "the genesis of knowledge and not just the logical properties of its outcome." The book is divided into two parts: in the first, Hamlyn, employing a Piagetian framework and terminology, examines first the classical empiricist account of the genesis of knowledge, which, after Piaget, he strictures as "genesis without structure." This account fails to explain the existence of intersubjective agreement. Then Hamlyn goes on to examine the rival rationalist account, which he strictures as "structure without genesis." Here, the failure is that there is no good account of how knowledge even gets started. Finally, Hamlyn examines an account of the growth of knowledge to which he is more sympathetic; that of the French psychologist, Piaget: "structure with genesis." Hamlyn finds striking similarities between the Piagetian theory and that of Kant, but, in the end, this account has a fatal flaw as well. Indeed, according to Hamlyn, all three accounts really fail for the same basic cause, viz., their account of knowledge is too egocentric, and "they all start from the same starting point, the individual set against his environment." In the second part of the book, Hamlyn sets out his own view, the object of which is to correct the egocentric view of knowledge which undermines the traditional theories and even their more modern versions, in Chomsky as the representative of Rationalism, and Piaget, as the Kantian representative. Here Hamlyn argues that knowledge would be impossible without what Wittgenstein called "agreement in judgments" and then argues that this implies common reactions, attitudes, wants, and interests, in relation to the world. Finally, Hamlyn proceeds to apply this "social view" of knowledge and understanding to the acquisition of both in the case of the child. In the course of doing so, he relates the acquisition of knowledge and understanding in the child to the child’s acquisition of language. In the course of his discussion, Hamlyn has interesting things to say about a wide variety of topics such as "non-epistemic seeing" and the relations between knowledge and understanding. In addition he provides illuminatingly critical discussions of the main ideas of Piaget and Chomsky; and although most philosophers are persuaded that they should become familiar with the ideas of the latter, Hamlyn makes out a good case that philosophers ought to start to think about the work of the former as well. All of this is done in a pleasingly straightforward way, devoid of any tiresome literary conceits.
