ABSTRACT
We have now a description of some of the main features of the theory of economic knowledge most widely accepted in the twentieth century, and we have seen also how its plausibility and influence may be explained by placing it in appropriate historical and political context. In this chapter we shall examine some of the main difficulties and paradoxes which happen to arise with this theory. These have been serious in their implications, and the more general problems from which they derive have been well known to many contemporary philosophers, yet they do not appear to have been given adequate notice by modern economists.1
