Episteme

Episteme means knowledge, as in "justified true belief" in the terminology of the philosopher Plato. It is etymologically derived from the Ancient Greek word ἐπιστήμη for knowledge or science, which comes from the verb ἐπίσταμαι, "to know". Episteme as knowledge contrasts doxa, Plato's term for common belief or opinion. Episteme is distinguished from techne, which is knowledge in an applied way as in a craft. The word epistemology, means the study of knowledge, and is derived from episteme.
