A particularly important topic for Marxist theory is that of popular politics: the ways in which the underclasses of society express their interests and values through collective action. Classical Marxism postulates a fundamental conflict of interest among classes. It holds that exploited classes will come to an accurate assessment of their class interests, and will engage in appropriate collective actions to secure those interests. The result is a predicted variety of forms of underclass collective action: boycotts, rent strikes, tax and (...) food riots, rebellion, and revolution. Underclass members of society instigate and support such protests because it is in their material class interest to do so. It will emerge, however, that this account is too schematic to provide a basis for explanation of popular politics. The microfoundations approach to Marxist theory will prove useful in this context because it directs us to some of the resources needed to provide a more adequate account of popular collective action.

One branch of Alvin Goldman's proposed "scientific epistemology" is devoted to the scientific study of how folk epistemic evaluators acquire and deploy the concepts of knowledge and justified belief. The author argues that such a "descriptive epistemology," as Goldman calls it, requires a more sophisticated theory of interpretation than is provided by the simulation theory Goldman adopts. The author also argues that any adequate account of folk epistemic concepts must reconstruct the intersubjective conceptual roles those concepts play in discursive practices. (...) In other words, descriptive epistemology also requires a theory of communicative action and an account of the practical abilities agents must have to engage in discursive practices. (shrink)

According to the instrumentalism of Friedman and Machlup it is irrelevant whether the explanatory principles or “assumptions” of a theory satisfy any criterion of “plausibility,” “realism,” “credibility,” or “soundness.” In this view the main or only criterion for selecting theories is whether a theory yields empirically testable implications that turn out to be consistent with observations. All we should require or expect from a theory is that it is a useful instrument for the purpose of prediction. Considerations of the “efficiency” (...) of a theory for the purpose of ordering our experiences are permitted, but considerations of “plausibility” are not. “Explanatory assumptions” are not really explanatory in the sense that they claim to represent underlying causal processes in reality; they only serve to generate, by deduction, implications that are in accordance with as many observations as possible.
