Philosophical theories often hinge on claims about what is necessary or possible. But what are possibilities and necessities, and how could we come to know about them? This book aims to help demystify the methodology of philosophy, by treating such claims not as attempted descriptions of strange facts or distant 'possible worlds', but rather as ways of expressing rules or norms.
Comment: Excellent addition to any course on modal metaphysics which wants to incorporate non-descriptive approaches to modality. Chapter 1 is a particularly good historical overview of conventionalism about modality and perfect for a more introductory course. Chapters 2 - 5 focuses on outlining Thomasson's own view and discusses objections and would be perfect for a more detailed or advanced course. Similarly with Chapters 6 - 8 which discuss the ontological, epistemological and methodology advantages of her view.
