Abstract: This chapter provides both a general overview of the book and summaries of the subsequent chapters. Questions raised include: Is debate over the norms of practical rationality a theoretical matter? How do practical considerations enter into the theoretical domain? What is the relation between reasoning and rationality? Between reasons and rationality? Between rationality and consistency? Is it irrational to have false beliefs and bizarre preferences? Is it irrational to be immoral? Are we rational? Are the “standard” norms of rationality gender-biased?

Keywords: belief, consistency, gender, immorality, irrationality, practical, preference, reasoning, theoretical,
