This book distinguishes itself from much of the polemical literature on these issues by offering the most judicious and well-balanced account yet available of animals' moral standing, and related questions concerning their minds and welfare. Transcending jejune debates focused on utilitarianism versus rights, the book offers a fresh methodological approach with specific and constructive conclusions about our treatment of animals. David DeGrazia provides the most thorough discussion yet of whether equal consideration should be extended to animals' interests, and examines the issues of animal minds and animal well-being with an unparalleled combination of philosophical rigor and empirical documentation. His book is an important contribution to the field of animal ethics and will be read with special interest by all philosophers teaching such courses, as well as biologists, those professionally involved with animals, and general readers concerned about animal welfare.
