Thomas S. Kuhn's classic book is now available with a new index.

Genetic epistemology analyzes the growth of knowledge both in the individual person (genetic psychology) and in the socio-historical realm (the history of science). But what the relationship is between the history of science and genetic psychology remains unclear. The biogenetic law that ontogeny recapitulates phylogeny is inadequate as a characterization of the relation. A critical examination of Piaget's Introduction à l'Épistémologie Généntique indicates these are several examples of what I call stage laws common to both areas. Furthermore, there is at (...) least one example of a paradoxical inverse relation between the two — geometry. Both similarities and differences between the two domains require an explanation, a developmental explanation. Although such an explanation seems to be psychological in nature, it is not merely empirical but also normative (since psychology is both factual and normative according to Piaget). Hence genetic epistemology need not be reduced to psychology (narrowly conceived), but rather should be seen as being both empirical and normative and thus similar to certain types of contemporary philosophy of science.

Piaget's social psychology is not widely discussed among psychologists, partly because much of it is still contained in untranslated French works. In this article I summarize the main lines of Piaget's social psychology and briefly indicate its relation to current theories in social psychology. Rejecting both Durkheim's sociological holism and Tarde's individualism, Piaget advances a sociological relativism in which all social facts are reducible to social relations and these, in turn, are reducible to rules, values and signs. Piaget's theory of (...) social values takes the form of a social exchange theory characterized in an abstract logical way. Piaget claims social exchange requires normative principles of reciprocity and that individual social development results in such an equilibrium because rationality itself is social and based upon social cooperation. These views, in turn, derive from Piaget's orthogenetic views concerning the course of evolution: development can be characterized as an increase in equilibrium manifested both in individual action and in social interaction.

Problem solving has recently become a central topic both in the philosophy of science and in cognitive science. This paper integrates approaches to problem solving from these two disciplines and discusses the epistemological consequences of such an integration. The paper first analyzes problem solving as getting a true answer to a question. It then explores some stages of cognitive activity relevant to question answering that have been delineated by historians and philosophers of science and by cognitive psychologists and artificial intelligencers. (...) The traditional opposition between discovery and justification is challenged. It is suggested that epistemology may be conceptualized, in part, as the critical assessment of problem-solving strategies. (shrink)

Although the theory of Jean Piaget is correctly characterized as genetic epistemology, its nature and scope remain unclear and controversial. An examination of Piaget's Introduction a l'epistemologie genetique indicates that Piaget relies heavily upon a model of comparative anatomy and, consequently, that genetic epistemology is about both the history of science and individual development. This biological model seems to be the basis for Piaget's view that the history of science can be seen as a (Kantian) history of scientific concepts whereas (...) psychogenetic development is a history of these very same concepts on the individual level. Finally, although there are passages indicating a different interpretation of the scope of genetic epistemology, I give several reasons for preferring the more liberal interpretation. (shrink)

Several philosophers have questioned the possibility of a genetic epistemology, an epistemology concerned with the developmental transitions between successive states of knowledge in the individual person. Since most arguments against the possibility of a genetic epistemology crucially depend upon a sharp distinction between the genesis of an idea and its justification, I argue that current philosophy of science raises serious questions about the universal validity of this distinction. Then I discuss several senses of the genetic fallacy, indicating which sense of (...) ‘genesis’ is relevant to epistemology. Next I consider the objection that psychology is irrelevant to epistemology, and that since "genetic epistemology" is really psychology, "genetic epistemology" is irrelevant to a real epistemology. Finally, I take up the objection that nothing discovered in genetic psychology could be relevant to a genetic epistemology. These last two arguments are based upon what I claim to be a mistaken notion of the nature of psychology. Suitably interpreted, psychology can assist genetic epistemology precisely in the way that the history of science assists current philosonhv of science. *I owe considerable thanks to Jann Benson, Ken Freeman, Bernie Rollin and Ron Williams for their helpful discussions concerning many of the issues discussed in this paper. I also wish to thank David Hamlyn, John Heil, William Lycan, Harvey Siegel and an anonymous reviewer for their comments and suggestions. It goes without saying that none of these individuals (especially Hamlyn and Siegel) necessarily agree with me. An earlier version of this paper was read at Colorado State University where the audience's comments were beneficial. (shrink)

Les Œuvres respectives de Piaget et de Kuhn sont des études sur l'évolution d'un certain type de connaissance: la connaissance enfantine chez Piaget, la physique et la chimie chez Kuhn. Dans les deux cas, on essaie d'analyser les facteurs qui déterminent les changements des contenus de la connaissance, et les relations qui existent entre ces divers contenus successifs. Il nous semble qu'une comparaison de ces deux études révèle des convergences intéressantes pour la théorie de la connaissance.
