Intuition and construction

the long version

Many normative theorists have advocated constructivism as a way of overcoming skepticism and nihilism. They have produced three types of constructivism that correspond to three conceptions of rationality: formal (Hare and Gewirth), instrumental (Gauthier), and ideal (Rawls). In this book, T.K. Seung examines these three types and vindicates Rawls' claim that only the constructivism of ideal rationality - which accepts Kantiam ideals as its basis - is viable. Unlike Rawls, however, Seung traces Kantian ideas to Platonic forms. Without this Platonic move, he shows, ideal constructivism cannot avoid collapsing to normative positivism. Seung maintains that Platonic forms are the obects of normative intuition and that they are only schematic ideas and principles that must be articulated into a system of concrete normative standards. This process of articulation is normative construction. Contrary to the conventional wisdom that constructivism and intuitionism are in competition with each other, Seung demonstrates the necessity of their natural dependence. That is, their happy union alone can provide a secure foundation for normative theories and save them from the twin evils of scepticism and nihilism.
