Peter Singer is one of the most famous bioethicists in the world. His controversial opinions disseminated in his countless publications and his undoubtedly good erudition made him very popular. Using logical arguments he always tries to prove that only a conscious being, a person, has the right to live. No wonder that his opponents call him "the famous death messenger". Australian philosopher is an ethic relativist in the way that he resigns from objective values in his conception. Moreover, he doesn't (...) approve unchangeable moral principles. According to him such moral values as 'good' and 'bad' are relative, depending on consequences which decide what is right in particular situation. He is polemical to traditional ethic adherents who value every human life. There is no objective life category in his conception. Life can be only considered according to its quality and, therefore, only beings possessing feelings and consciousness are subjects of morality. They only have the right to live. (shrink)
