Animals and Science examines the debates, from the Renaissance to the present, surrounding issues of animal rights, consciousness, and self-awareness.

Animals and Science examines what science has (and has not) taught us about the nature of nonhuman animals and explores the moral, religious, social, and scientific implications of those teachings. It shows how the scientific study of animals, especially their cognitive abilities, has transformed our understanding of them. Animals and Science traces our evolving understanding of animal pain and considers its moral relevance to humans. It discusses Darwin's belief-shattering notion that species differences are not absolute, then traces its impact to the present day.

Ultimately, Animals and Science is about the nature of science-the kinds of questions science can and cannot answer, and the role of theory in shaping the interpretation of evidence.
