Abstract

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.
