ABSTRACT
This chapter deals with the concept of the concrete universal. The notion of the concrete universal is complex and cannot be neatly summed up in a few sentences or even paragraphs. It says that first the essentials of the notion of the concrete universal must be grasped when it is free from ambiguity. At the beginning of this chapter the notion of the concrete universal is bound up with a theory of rational activity. The aim of this chapter is to expound the notion of the concrete universal and the theory of rational activity because it is bound up with that notion. The chapter discusses how the notion of the concrete universal is significant within the context of rational activity. It gives a provisional statement of the nature and scope of philosophy based on the theory of rational activity and the notion of the concrete universal has already been given.
