Barry Allen postulates that the unit of knowledge is artifact and rejects traditional idea that knowledge consists of true, justified beliefs. Analysis of Allen's concept of knowledge, being a restrictive form of pragmatism, shows that the epistemological change proposed by him is radical to a great degree. Allen neglects all important epistemological distinctions and categories. The concept is rooted in a different culture, activist and one-sidedly pragmatic, far from this one ( which emerged from the ancient Greek ideas) that constitutes a basis for all traditional epistemological models of knowledge.
