Forms of Truth and the Unity of Knowledge addresses a philosophical subject—the nature of truth and knowledge—but treats it in a way that draws on insights beyond the usual confines of modern philosophy. This ambitious collection includes contributions from established scholars in philosophy, theology, mathematics, chemistry, biology, psychology, literary criticism, history, and architecture. It represents an attempt to integrate the insights of these disciplines and to help them probe their own basic presuppositions and methods. The essays in Forms of Truth and the Unity of Knowledge are collected into five parts, the first dealing with division of knowledge into multiple disciplines in Western intellectual history; the second with the foundational disciplines of epistemology, logic, and mathematics; the third with explanation in the natural sciences; the fourth with truth and understanding in disciplines of the humanities; and the fifth with art and theology.

Ayala, Zygmunt Pizlo, Osborne Wiggins, Allan Gibbard, Carsten Dutt, Aviezer Tucker, Nicola Di Cosmo, Michael Lykoudis, and Celia Deane-Drummond.
