Ancient Epistemology

Theodore Scaltsas

Research output: Chapter in Book/Report/Conference proceedingChapter (peer-reviewed)peer-review


I propose a new understanding of the Ancient Greek philosophical accounts of knowledge, arguing that their accounts are more akin to a perceptual model of knowledge than to a justificatory one. Just as until recently our accounts of knowledge were captured by the generic formula JTB: 'justified true belief', on my reading, the Ancient Greek accounts of knowledge are captured by CTB: 'constitutional true belief'. Knowledge, for them, is revelatory in the way perception is, namely, being true belief about the constitution of the objects of belief. I argue that the Presocratics; Plato; Aristotle; and the Stoics, understood knowledge along this constitutional model.
