For Riverside Redneck:An epistemology is a study of the nature knowledge. So in other words, faith is not a reliable way of determining knowledge or truth. For example, using faith, how would one determine which religion is "true"? They obviously can't all be true, because they all contradict each other in various ways, and thus at least some of them are false. Using faith, how to we determine which are true or false?
Experience and experiment (empiricism) can be a path to knowledge. If every time I heat ice to 32°F it melts, I know something. Conflicting ideas cannot be supported by evidence.
Pure reason (rationalism) can be a path to knowledge. It tells us that 7+4=11, and unless we redefine what those symbols mean, no opposite opinion can be supported by reason.
But faith (fideism) can't possibly be a path to truth or knowledge since any position and its opposite can be held by faith.
