ABSTRACTAlthough Thomas Piketty is largely known for his recent empirical contributions to the study of inequality, his work on epistemology has been substantial. It remains relatively unreferenced in the political epistemology literature both because it has been overshadowed by his work on inequality and because it was written for an audience of economists rather than political scientists. Piketty’s work on these themes can be divided into analyses of political belief formation and analyses of the epistemic properties of democratic institutions. Capital (...) in the Twenty-First Century, Piketty’s recent book, also reflects his long-standing interest in epistemological questions. The major epistemic claim of that book is that political knowledge is an endogenous phenomenon: policy generates new knowledge over the course of its administration. One of the benefits of the primary policy proposal of Capital, the global wealth tax, is that it will generate new knowledge about wealth inequality. (shrink)

ABSTRACTIlya Somin's Democracy and Political Ignorance represents a missed opportunity to fully examine the implications of public ignorance in modern democracies. Somin persuasively argues that existing levels of public ignorance undermine the main normative accounts of democratic legitimacy, and he demonstrates that neither cognitive shortcuts nor heuristics can provide a quick fix for democracy. However, Somin seeks to find a simple explanation for public ignorance in the conscious, rational choices of voters. He thus commits to the position that voters choose (...) to be ignorant and irrational—and to the simplistic implication that given the right incentives they would choose otherwise. This position is empirically problematic, methodologically flawed, and theoretically redundant. On the more plausible view that ignorance is the inadvertent result of social complexity, it is clear that simply focusing on incentives tells us little about what voters would or would not know under different institutional circumstances.

Mark Pennington’s Robust Political Economy is a systematic exposition of a framework for analyzing institutional performance. The Robust Political Economy framework evaluates institutions according to their ability to solve knowledge and incentive problems. On grounds of robustness, Pennington combines insights from Austrian market-process theory and public-choice theory to defend classical liberalism from several compelling critiques. These include theories of market failure in economics; communitarian, deliberative-democratic, and liberal-egalitarian theories of justice; and concerns with social capital, domestic and international poverty, and ecology.
