This engaging introduction to the fundamental issues of philosophy will prompt students to think actively about questions such as: Does God exist? Do we have souls? Does human life have meaning? Is there a real difference between right and wrong? and many more. Organized topically, the twelve chapters in the book focus on key philosophical questions and discuss alternative answers (solutions). Author Emmett Barcalow includes readings in every chapter by famous thinkers and well-known philosophers who offer their own answers to these questions--for example, the thoughts of Charles Darwin, Benjamin Franklin, and Mohandas K. Ghandi on the existence of God; Plato's ideas on the body/mind connection; and John Stuart Mill and Immanuel Kant's theories of right and wrong. As students progress through the text, they'll begin to think critically and decide for themselves which answers seem the most reasonable to them. Definitions and other relevant information are placed in the margins for easy reference, and brain teasers--questions for class discussion and student reflection-- are integrated throughout. The text also features insightful discussion and review questions at the end of each chapter and two valuable appendices: one on reading philosophy and the other on writing a philosophy paper. The third edition adds chapter objectives; information on philosophy's subfields; a section on self-knowledge; new material on reflective equilibrium; expanded coverage of the social justification of morality; a new discussion of equal opportunity; a discussion of Feinberg's analysis of four liberty limiting principles; and more. It also adds readings by Rahula, Sartre, Russell, St. Augustine, Constant, Rousseau, and many others.
