A collection of 17 essays exploring the central issues of the philosophy of the mind, and human interaction with psychology and evolutionary biology. This book questions the relationship between psychology and morality as well as exploring the concept of human intentionality. It argues that intentional attributes such as desires, goals, beliefs and knowledge are purely mechanistic. The author also considers the meaning of mental imagery, sensations, pain and other puzzling aspects of consciousness. Central to the discussion of the book is the question of whether psychology can support a vision of humans as moral agents, free to choose what they do and responsible for their actions.
