"The present work shares the same objective as a former book of one of the authors, Systems of Ethics and Value Theory, an attempt to provide a thorough summary, explanation, and critical evaluation of classics in philosophy, with the author's explanations richly interspersed with quotations from the classics, the hope being that the reader will benefit from significant inflections of the classic philosophers speaking for themselves, along with the guide provided in the present exposition." - Preface.
