For those unfamiliar with this fascinating domain, Institutional Epistemology and Extreme Inequality: Knowledge and Governance in a Non-ideal World can serve as an excellent introduction to the field of institutional epistemology. Even more impressively, Marko-Luka Zubcic brings to the fore, not one, but two cutting-edge contributions, both advancing the research frontier. First, suggesting an original, unifying framework that brings together the distinctive schools of thought that have shaped the field so far. Second, Institutional Epistemology and Extreme Inequality identifies and analyzes economic inequality: an important but previously neglected factor determining the epistemic performance of institutional systems or regimes. In brief, an impressive and notable effort to advance the analytical and normative relevance of a research program exploring innovatively the interface between institutional structures, epistemic processes, and political order.
