Epicurus Quotes on Knowledge

Epicurus's epistemology — the canonic — is preserved chiefly through the Letter to Herodotus, the Principal Doctrines, and the doxographic summaries in Diogenes Laertius and Sextus Empiricus. The doctrine that all sensations are true, in the specific sense that each impression is a faithful registration of the atomic films (eidola) that produced it, locates perceptual error not in sensation itself but in the judgment the mind subsequently superimposes upon it. The further criteria of preconceptions (prolēpseis) and feelings of pleasure and pain supply the corresponding instruments by which the wise person tests propositions about the unobserved and orients the practical life toward the stable pleasure (ataraxia) that constitutes the human good.
