This work discusses animal rights, obligations concerning future generations, abortion, limiting medical treatment, and euthanasia. Persons are defined as individuals who ought to be treated in accordance with all sound moral principles. The author develops an account of what moral principles are sound, how we can apply them to complex situations, and what makes it reasonable to treat individuals in accordance with particular moral principles. Summaries of the theoretical conclusions are included to enable non-professionals to follow the discussion of practical issues. The book should interest not only professional philosophers, but also non-philosophers concerned with problems in medical and environmental ethics, abortion, and animal rights.
