Critical Realism

In the philosophy of perception, critical realism is the theory that some of our sense-data (for example, those of primary qualities) can and do accurately represent external objects, properties, and events, while other of our sense-data (for example, those of secondary qualities and perceptual illusions) do not accurately represent any external objects, properties, and events. Put simply, critical realism highlights a mind-dependent aspect of the world, which reaches to understand (and comes to understanding of) the mind independent world.

Contemporary critical realism most commonly refers to a philosophical approach associated with Roy Bhaskar. Bhaskar's thought combines a general philosophy of science (transcendental realism) with a philosophy of social science (critical naturalism) to describe an interface between the natural and social worlds. Critical realism can, however, refer to several other schools of thought, such as the work of the American critical realists (Roy Wood Sellars, George Santayana, and Arthur Lovejoy). The term has also been appropriated by theorists in the science-religion interface community. The Canadian Jesuit Bernard Lonergan developed a comprehensive critical realist philosophy and this understanding of critical realism dominates North America's Catholic Universities.
