This book collects original essays on the epistemology of modality and related issues in modal metaphysics and philosophical methodology. The contributors utilize both the newer "metaphysics-first" and the more traditional "epistemology-first" approaches to these issues. The chapters on modal epistemology mostly focus on the problem of how we can gain knowledge of possibilities, which have never been actualized, or necessities which are not provable either by logico-mathematical reasoning or by linguistic competence alone. These issues are closely related to some of the central issues in philosophical methodology, notably: to what extent is the armchair methodology of philosophy a reliable guide for the formation of beliefs about what is possible and necessary. This question also relates to the nature of thought experiments that are extensively used in science and philosophy. Epistemology of Modality and Philosophical Methodology will be of interest to researchers and advanced students working on the epistemology and metaphysics of modality, as well as those whose work is concerned with philosophical methodology more generally.

The philosophy of modality investigates necessity and possibility, and related notions—are they objective features of mind-independent reality? If so, are they irreducible, or can modal facts be explained in other terms? This volume presents new work on modality by established leaders in the field and by up-and-coming philosophers. Between them, the papers address fundamental questions concerning realism and anti-realism about modality, the nature and basis of facts about what is possible and what is necessary, the nature of modal knowledge, modal logic and its relations to necessary existence and to counterfactual reasoning. The general introduction locates the individual contributions in the wider context of the contemporary discussion of the metaphysics and epistemology of modality.

This collection highlights the new trend away from rationalism and toward empiricism in the epistemology of modality. Accordingly, the book represents a wide range of positions on the empirical sources of modal knowledge. Readers will find an introduction that surveys the field and provides a brief overview of the work, which progresses from empirically-sensitive rationalist accounts to fully empiricist accounts of modal knowledge. Early chapters focus on challenges to rationalist theories, essence-based approaches to modal knowledge, and the prospects for naturalizing modal epistemology. The middle chapters present positive accounts that reject rationalism, but which stop short of advocating exclusive appeal to empirical sources of modal knowledge. The final chapters mark a transition toward exclusive reliance on empirical sources of modal knowledge. They explore ways of making similarity-based, analogical, inductive, and abductive arguments for modal claims based on empirical information. Modal epistemology is coming into its own as a field, and this book has the potential to anchor a new research agenda.

This monograph articulates and defends a theory-based epistemology of modality (TEM). According to TEM, someone justifiably believe an interesting modal claim if and only if (a) she justifiably believes a theory according to which that claim is true, (b) she believes that claim on the basis of that theory, and (c) she has no defeaters for her belief in that claim. The book has two parts. In the first, the author motivates TEM, sets out the view in detail, and defends it against a number of objections. In the second, the author considers whether TEM is worth accepting. To argue that it is, the author sets out criteria for choosing between modal epistemologies, concluding that TEM has a number of important virtues. However, the author also concedes that TEM is cautious: it probably implies that we are not justified in believing some interesting modal claims that we might take ourselves to be justified in believing. This raises a question about TEM's relationship to Peter van Inwagen's modal skepticism, which the author explores in detail. As it turns out, TEM offers a better route to modal skepticism than the one that van Inwagen provides. But rather than being a liability, the author argues that this is a further advantage of the view. Moreover, he argues that other popular modal epistemologies do not fare better: they cannot easily secure more extensive modal justification than TEM. The book concludes by clarifying TEM’s relationship to the other modal epistemologies on offer, contending that TEM need not be a rival to those views, but can instead be a supplement to them.

In this book, Mikhail Epstein offers a systematic theory of modalities (possible, actual, necessary) and their impact on the philosophy and culture of modernity and postmodernity, focusing on the creative potentials of possibilistic thinking for the humanities.
