The theory of knowledge (or epistemology) is arguably a foundational theory for our understanding of the world. Intuitively, however, it would seem quite detached from our everyday lives. What could the philosophical question of whether an objective framework of knowledge could be established, or whether I am just dreaming the world have to do with, say, what economic system I would prefer to live in? But the reason for this common-sense intuition is that, for the most part, it presupposes a particular, objectivist theory of knowledge à la Popper. It would seem that we could argue about the best economic system independent of how knowledge is attained, whereas in reality the former arguments rest on a particular way of attaining the knowledge contained in them.

In this objectivist theory we can never be certain, in its logical sense, of the truth of our theories (knowledge). The best that we can do is to criticise them and discard the ones we find to be false. This asymmetric situation between truth and falsehood is the basis of the method of trial and elimination of error and of scientific discoveries (growth of knowledge). Once we accept this, it follows more or less directly that the best economic system is the one that allows such trials-and-errors to be performed at the minimum cost to allow the maximum growth of knowledge. This is possible, so far as we know, only in a free-market system, that is, capitalism.
