How do we know anything? Do we know because ‘science says so’ or because ‘the Bible tells me so’ or because ‘it just feels right and I know it inside myself’? Do we know everything in the same way? Can different ways of knowing fit together in one life and reality? In this concise volume, the second book of a trilogy, international speaker Ellis Potter shows how four basic ways of knowing can be integrated to make us more fully human. His first book—3 Theories of Everything—has been translated into fourteen languages since its publication in 2012.
