How do we know stuff? Like all of the great philosophical quandaries, it’s a fundamentally straightforward question that can lead us into an endlessly branching series of chicken-and-egg meditations on the nature of existence (ontology) versus the nature of knowledge (epistemology). In this fascinating episode of The Ken Show, we take a look at a dozen of the most popular schools of epistemological thought — idealism, pragmatism, empiricism, constructivism, etc. — noting their respective contributions and limitations, and how they can all be pulled together into a more Integral epistemology.
