This paper examines the nomic covariationist strategy of using idealization to define representation. While the literature has focused upon the possibility of defining ideal conditions for perception, I argue that nomic covariationist appeals to idealization are pseudoscientific and contrary to a foundational and empirically well-supported methodological presupposition in cognitive science. Moreover, one major figure in this camp fails to come to grips with its role and its problems in mainstream science. Thus he forwards a false dichotomy of the sciences and (...) treats idealization as a blank check written by scientists on an unknown bank. Finally, I consider and reject alternative formulations of the nomic covariationist's idealization strategy. (shrink)

Rosenberg applies current thinking in philosophy of science to neoclassical economics in order to assess its claims to scientific standing. Although philosophers have used history and psychology as paradigms for the examination of social science, there is good reason to believe that economics is a more appropriate subject for analysis: it is the most systematized and quantified of the social sciences; its practitioners have reached a measure of consensus on important aspects of their subject; and it encompasses a large number (...) of apparently law-like propositions.

In investigating their models, economists do not appear to engage much in the activities many philosophers take to be essential to scientific understanding of the world, activities such as testing hypotheses and establishing laws. How, then, can economic models explain anything about the real world? Borrowing from William Dray, an explanation of what something really is, as opposed to an explanation of why something happens, is the subsumption of the explanandum under a suitable concept. One way economic models explain real-world (...) phenomena is by providing explanations-what of such phenomena. In this way, economic models can afford explanations of the world without necessarily involving the activities philosophers take to be integral to scientific understanding of the world, for explanations-what do not necessarily involve the activities in question.

This 1996 book defends the prospects for a science of society. It argues that behind the diverse methods of the natural sciences lies a common core of scientific rationality that the social sciences can and sometimes do achieve. It also argues that good social science must be in part about large-scale social structures and processes and thus that methodological individualism is misguided. These theses are supported by a detailed discussion of actual social research, including theories of agrarian revolution, organizational ecology, (...) social theories of depression, and supply-demand explanations in economics. Professor Kincaid provides a general picture of explanation and confirmation in the social sciences and discusses the nature of scientific rationality, functional explanation, optimality arguments, meaning and interpretation, the place of microfoundations in social explanation, the status of neo-classical economics, the role of idealizations and non-experimental evidence, and other specific controversies.

This collection brings together the essays of one of the foremost American philosophers of economics. Cumulatively they offer fresh perspectives on foundational questions such as: what sort of science is economics? and how successful can economists be in acquiring knowledge of their subject matter?

Challenges the widely held view that good models must necessarily be simplifications and hence cannot be true. This is done by distinguishing between whole truth (complete description) and truth (essential description, attained by the method of isolation).
