This long-awaited book is a gem. It is a comprehensive survey of the state of the art in the theory of parts and wholes, particularly as work on that topic is carried on in philosophy and logic...This is a work that is clear, careful, and judicious...interesting and engaging...a must-have work, not just for those primarily concerned with mereology, but for anyone who finds the theory of parts and wholes relevant for their thinking. Cotnoir and Varzi have done the profession a great service. This book will serve as the new standard and touchstone for work in mereology for decades to come * Daniel Nolan, Notre Dame Philosophical Reviews * The blurb on the back cover claims that in this book, it is possible to find all the tools needed to 'theorize about all things mereological'. The book fulfills this promise. An impressive variety of theories are systematized and compared. Attention is paid to both their philosophical motivations and their technical aspects * Giorgio Lando, Philosophical Quarterly *
