Sidney Hook on Pragmatism, Democracy, and Freedom

Were the phrase not so encrusted with misleading associations, I should call my philosophy "dialectical materialism"; materialism, because its explanations make no appeal to entities or processes which are not empirically verifiable by scientific method or logically inferrible from experienced data; dialectical, because it holds (a) that there is an implied temporal reference in every description or generalization, (b) that the processes of discovery and interpretation-as distinct from the validity of their results-cannot be completely dissociated from the socio-historical culture of the age, and (c) that under certain conditions, human thinking, construed as meaningful selective behavior and not as a passive reflection or image of the external scene, plays a creative role in the world.
