Polanyi’s post-critical epistemology is empirical and not transcendental but it grounds knowledge in perception; knowledge is thus primarily aesthetical and only partly conceptual. The conceptual is always embedded in the perceptual and comprehension or judgment always has an integrative structure. Polanyi’s tacit knowledge is pre-conscious and must be distinguished from the personal which implies conscious commitment. If knowledge produces a cathartic effect, then it is more than merely tacit. The Polanyian revolution in epistemology argues that the human ability to reach truth through use of our cognitive powers is an art.

An exploration of the relationship between imagination and intuition and the workings of visual perception, in light of Polanyi’s epistemology, helps us to understand aesthetic seeing. The artist and contemplative learn to see anew and accordingly grasp extraordinary coherences of meaning.

How do we know the degree of imagination involved in knowing a reality? This is essentially an epistemological question. This essay discusses first the role of imagination in Polanyi’s epistemology since it is used here as the basis of integrative reality. The essay then discusses the degree of imagination involved in three types of integrative reality that are found respectively in technology, science, and humanities. It concludes with a discussion on the role of imagination in education.
