Philosophy is an activity of thought, a type of thinking. Philosophy is critical and comprehensive thought, the most critical and comprehensive manner of thinking which the human species has yet devised. This intellectual process includes both an analytic and synthetic mode of operation. Philosophy as a critical and comprehensive process of thought involves resolving confusion, unmasking assumptions, revealing presuppositions, distinguishing importance, testing positions, correcting distortions, looking for reasons, examining world-views and questioning conceptual frameworks.
