This text explores how phenomenology might lead to monadological metaphysics, and conversely, how monadology might be helpful to nonmetaphysical thinking. Little has been published (especially in English) on the connections between these two fields and this edited volume is an invitation to assess the similarities and differences between Husserl’s philosophical projects and Leibniz’s metaphysics. Many Leibniz scholars have contributed to this volume. Phenomenologists covered include Stumpf, Brentano, Heidegger, Reinach, and Gurwitsch. This book appeals to scholars and advanced students working in the field.
