About

Overview

A comprehensive introduction to formal logic, LOGIC AND PHILOSOPHY: A MODERN INTRODUCTION is a rigorous yet accessible text, appropriate for students encountering the subject for the first time. Reading the text is much like having a talented and patient instructor walking a student through difficult concepts in a lecture or during office hours. Abundant carefully crafted exercise sets accompanied by a clear, engaging exposition give students a firm grasp of basic concepts, which build to an exploration of sentential logic, first-order predicate logic, the theory of descriptions, and identity. As the title suggests, this is a book devoted not merely to logic; students will also examine the philosophical debates that led to the development of the field.


Features/Benefits

  • Walk-Through sections: For crucial exercises, these "how-to" sections show, step by step, the process of solving a moderately difficult sample problem.
  • Coverage of basic concepts: Beginning with the first chapter, attention is paid to such topics as logical form and the relationship between consistency and validity. The fundamental concept of a semantic interpretation is used to provide a unified explanation of such basic concepts as validity, consistency, logical equivalence, and logical implication in both sentential and predicate logic.
  • Help for the mathematically anxious or averse: The text stresses the relationships between mathematical and philosophical concepts, in ways that are designed to engage student interest and to provide reader-friendly explanations of why the mathematical symbols work as they do.
  • Sections covering informal fallacies and modal logic, are available in an alternative versions of the text.
  • Glossaries following each chapter assist students in reviewing key concepts.
  • Answers to the even-numbered exercises are found in the back of the book, providing immediate feedback to students as they work through the exercises in the text.

What's New

  • Revised and updated exercises and explanations ensure that students receive an accurate and accessible introduction to logical concepts.
  • New feature on the "Logical Revolution" of the 20th century, and the debates among prominent philosophers and mathematicians that led to the creation of modern formal logic.
  • This edition offers three new appendices, one dealing with an alternative to conditional proof; one with predicate logic instantiations, including an extensive discussion of alternatives; and one with problematic translations.
  • In addition to revisions made to ensure accuracy of print and thought, this new edition of LOGIC AND PHILOSOPHY: A MODERN INTRODUCTION, 12E contains additional discussions of philosophical interest, such as: special historical discussions of key philosophers and logicians who have made substantive contributions to the development of modern symbolic logic; additions of material concerning definite descriptions and properties of relations (Chapter 13); a revised approach to the semantics of instantiation (Chapter 9); an in-depth discussion of assumptions using apparently free variables (Chapter 9); and a new discussion of demonstrating consistency of predicate logic statements, using interpretations and expansions (Chapter 10).
  • This edition is accompanied by several useful supplements, available through CourseMate. These resources include quizzing, supplemental chapters, and Logic Coach. For information on packaging CourseMate with the text, contact your Cengage Learning representative.

Efficacy and Outcomes

Reviews

"The book develops formal logic rigorously, but with an approach that students will find clear and accessible, especially with respect to the explanations of key concepts and the featured "walk-throughs" of proof techniques, etc."
— David Shier, Washington State University
"I would describe the book as a 'real logic book that is about as accessible as it gets."
— Michael Cole, Reedley College
