Identity, existence, predication, necessity, and truth are vital concepts at the center of philosophy. Yet Colin McGinn believes that orthodox views of these topics are misguided in important ways. Philosophers and logicians have often distorted the nature of these concepts in an attempt to define them according to preconceived ideas. Logical Properties aims to respect the ordinary ways we talk and think when we employ these concepts, while at the same time showing that they are far more interesting and peculiar than some have assumed; these notions correspond to real properties--logical properties--that challenge naturalistic metaphysical views. Written with a minimum of formal terminology, this book deals with logico-linguistic issues as well as ontological ones. The focus is on trying to get to the essence of the concept concerned, not merely finding some established notation for providing formal interpretations.About the Author: Colin McGinn is Professor of Philosophy at Rutgers University, New York.
