The concept of the good is inextricably linked to the concept of life or the form of life. Evaluating something as "good" - whether it is the scent of a flower or the actions of a person - follows a general pattern of natural normativity: "Good" is what is essential for the members of a species - whether plant, animal, or human. In "The Nature of the Good," Philippa Foot presents an impressive design of a naturalistic ethics and a sovereign summary of her lifelong efforts to achieve an appropriate understanding of the relationship between virtue and happiness. A classic of modern moral philosophy.
