In Part 3, Blackburn details some of the foundations for ethics, emanating from a search (throughout the text) for Reasons (capital R denoting a universality within a group, a cause, a society, or the world), and then narrowing the practical applicability of such. He also broaches the rationale on pp.105-106, that a goal of society may be to provide sufficient various incentives to minimize, rather than eliminate, nonpreferred behavior - that an element of social control is required alongside big universal Reasons. Do you find these two approaches harmonious? Why or why not?
