"Scientific naturalism - basing beliefs on empirical evidence - has now triumphed in every field of inquiry except moral philosophy. There it is still thought appropriate to cite otherworldly standards known by divine revelation or moral intuition. In Grounded Ethics, Max Hocutt argues that, since there is no transcendent reality on which to base the claims of ethics, normative truth must be sought in the desires of individuals and the conventions of societies.". "Hocutt's demonstration of this thesis will interest philosophers, behavioral biologists, sociologists and ethicists."--BOOK JACKET.
