Etymology: Greek, combined form of knowledge + discoursing
Definition: The theory or science of the method or grounds of knowledge, especially with regard to its methods, validity, and scope, and the distinction between justified belief and opinion.
So…it’s the nature of knowledge and your personal epistemology is your personal beliefs about how you acquire knowledge, how you communicate knowledge, and knowledge’s nature–whether it is hard and tangible or subjective and fluid.
(from the Oxford English Dictionary)
