Philips defends a middle ground between the view that there is a set of standards binding on rational beings as such (universalism) and the view that differences in morals reduce ultimately to matters of taste (skepticism). He begins with a sustained critique of universalist moral theories andsome familiar approaches to concrete moral questions that presuppose them (most appeals to intuitions, respect for person's moralities, and versions of contractarianism and wide reflective equilibrium). He goes on to criticize major recent attempts to develop nonuniversalist alternatives toskepticism, arguing that they rely on excessively abstract and philosophically indefensible preference satisfaction theories of the good. According to Philips's positive alternative, moral standards are justified to the extent that they support reasonably valued ways of life. He devotes considerableattention to clarifying this idea and draws conclusions from it about the role and limits of reason in ethics. Philips's theory provides us with a theoretical basis for dealing with actual moral controversies and for approaching questions of applied and professional ethics in a systematicway.
