Epistemology

Epistemology is one of the core areas of philosophy. It is concerned with the nature, sources and limits of knowledge (see Knowledge, concept of). There is a vast array of views about those topics, but one virtually universal presupposition is that knowledge is true belief, but not mere true belief (see Belief and knowledge). For example, lucky guesses or true beliefs resulting from wishful thinking are not knowledge. Thus, a central question in epistemology is: what must be added to true beliefs to convert them into knowledge?
