ΕΠΙΣΤΗΜΗ
Episteme, in classical Greek thought, is not merely knowledge, but rather systematic, certain, and immutable knowledge, sharply contrasted with unstable doxa (opinion). It forms the core of the philosophical quest for truth, particularly in Plato and Aristotle, and is intrinsically linked to the understanding of causes and first principles. Its lexarithmos (651) suggests a complex and structured entity.
Definition
According to the Liddell-Scott-Jones Lexicon, ἐπιστήμη is initially defined as "knowledge, understanding, skill, experience." However, in classical philosophy, and especially in Plato and Aristotle, its meaning acquires deeper and more specialized dimensions. It is not merely the accumulation of information, but a well-founded and reasoned understanding of reality.
In Plato, ἐπιστήμη is explicitly distinguished from δόξα (opinion). While δόξα pertains to the world of sensible and mutable phenomena, ἐπιστήμη is directed towards the world of immutable and eternal Forms or Ideas, the true beings. It is the knowledge acquired through reason and dialectic, leading to certainty and truth, in contrast to unstable and subjective opinion.
Aristotle, although disagreeing with Plato's theory of Forms, maintains the central importance of ἐπιστήμη as systematic and demonstrative knowledge. For Aristotle, ἐπιστήμη is the knowledge of universal and necessary causes, acquired through logical inference from first principles. It is scientific knowledge in the modern sense, explaining the "why" of things, not merely the "that."
Overall, ἐπιστήμη represents the pinnacle of human intellectual endeavor to understand the world in an objective, systematic, and truthful manner, transcending mere experience or subjective belief.
Etymology
Cognate words include the verb ἵστημι (to stand), στάσις (a standing, position), σύστημα (a system, a composite), ἐπιστάτης (overseer, superintendent), as well as other compound words with the prefix epi- that denote stability or superiority.
