What does it mean to know something? Can we have confidence in our knowledge? Epistemology, the study of knowledge, can often seem like a daunting subject. And yet few topics are more basic to human life. We are inquisitive creatures by nature, and the unending quest for truth leads us to raise difficult questions about the quest itself. What are the conditions, sources, and limits of our knowledge? Do our beliefs need to be rationally justified? Can we have certainty? In this primer on epistemology, James Dew and Mark Foreman guide readers through this discipline in philosophy. This second edition has been expanded with new material and now serves as the first volume in IVP's Questions in Christian Philosophy series. By asking basic questions and using clear, jargon-free language, they provide an entry into one of the most important issues in contemporary philosophy.
