The Deflationary Approach to Truth

Abstract This book presents a detailed, up-to-date, and historically informed survey and critical explication of the deflationary approach to the topic of truth. It is divided into three parts. Part 1 explains what deflationism about truth involves and develops a useful framework that clarifies how this approach differs from the traditional, “inflationary” approach. The framework illuminates certain general deflationary themes in terms of what is here called broad four-dimensional deflationism, which comprises four different dimensions that any deflationary account must satisfy. The book first examines the degree to which each of these dimensions is displayed in early, “proto-deflationary” accounts. It then, while explaining the details and historical development of the different contemporary species of deflationism, assesses the degree to which each version of them adheres to the deflationary dimensions, in addition to clarifying how each species differs from inflationism and how they all differ from one another. Part 2 of the book examines challenges to deflationism, systematizing them by considering the deflationary dimension that each targets and grouping the challenges in terms of them. For each challenge, this part explains its historical development and investigates the extent to which the most prominent contemporary deflationary accounts answer, or fail to answer, it. Part 3 of the book is an appendix that presents new directions for deflationism by developing a version of the approach that answers the challenges examined in Part 2. The three parts of the book together provide readers with a comprehensive overview of the challenges to and merits of the deflationary approach to truth.
