Is the history of life a series of accidents or a drama scripted by selfish genes? Is there an "essential" human nature, determined at birth or in a distant evolutionary past? What should we conserve—species, ecosystems, or something else?

Informed answers to questions like these, critical to our understanding of ourselves and the world around us, require both a knowledge of biology and a philosophical framework within which to make sense of its findings. In this accessible introduction to philosophy of biology, Kim Sterelny and Paul E. Griffiths present both the science and the philosophical context necessary for a critical understanding of the most exciting debates shaping biology today. The authors, both of whom have published extensively in this field, describe the range of competing views—including their own—on these fascinating topics.

With its clear explanations of both biological and philosophical concepts, Sex and Death will appeal not only to undergraduates, but also to the many general readers eager to think critically about the science of life.

In this provocative contribution to the philosophy of science and mind, Paul E. Griffiths criticizes contemporary philosophy and psychology of emotion for failing to take in an evolutionary perspective and address current work in neurobiology and cognitive science. Reviewing the three current models of emotion, Griffiths points out their deficiencies and constructs a basis for future models that pay equal attention to biological fact and conceptual rigor.

"Griffiths has written a work of depth and clarity in an area of murky ambiguity, producing a much-needed standard at the border of science, philosophy, and psychology. . . . As he presents his case, offering a forthright critique of past and present theories, Griffiths touches on such issues as evolution, social construction, natural kinds (categories corresponding with real distinctions in nature), cognition, and moods. While addressing specialists, the book will reward general readers who apply themselves to its remarkably accessible style."—Library Journal

"What Emotions Really Are makes a strong claim to be one of the best books to have emerged on the subject of human emotion."—Ray Dolan, Nature
