Who coined the term epistemology?
Epistemology
By contrast with empiricism and idealism, which centres around the epistemologically privileged status of sense data (empirical) and the primacy of Reason (theoretical) respectively, modern rationalism adds a third 'system of thinking', (as Gaston Bachelard has termed these areas) and holds that all three are of equal importance: The empirical, the theoretical and the abstract. For Bachelard, rationalism makes equal reference to all three systems of thinking.
