Pat Flynn is joined by Professor Peter Koch of Villanova University to discuss the nature of truth--what is truth?--and do we know what we know?  Many of us work off the assumption that truth is knowable and that our senses are reliable. But what happens when we question these assumptions? What happens when we attempt to define truth? These are some of the most important questions a person can ask in life, if that person is committed to finding out--if, and what--the meaning of life really is.  Join us for a deep (but accessible!) philosophical conversation on the nature of truth and exploring the study of epistemology, or we know what we know.
