An ideal teaching text, Introducing Philosophy: Questions of Knowledge and Reality is a stand-alone text organized into seven thematic parts to be covered during a single, semester-long course. It also provides various background readings and commentaries often requested by instructors, but all too often omitted in competing texts. These include a historical introduction, an introduction to logic, and a glossary. The collection also incorporates a discussion of scientific topics that have recently gained the attention of philosophers, such as the argument for the fine tuning of the universe, sociobiology, and ethics ("the selfish gene"). The revised edition includes a new chapter: Harry Frankfurt's influential essay, "Freedom of the Will and the Concept of a Person."
