Aetius the Doxographer Quotes on Knowledge

Aëtius (conventionally first or second century CE) is the conventional name assigned by Hermann Diels to the lost first-century compilation that supplies, through the parallel epitomes of Pseudo-Plutarch and Stobaeus, the principal later doxographic source for the doctrines of the pre-Socratic, Hellenistic, and early imperial philosophical schools. The framework preserved through Aëtius — organized topically rather than by school, with each topic surveying the positions of the major philosophers in turn — supplied the format on which Diels's Doxographi Graeci (1879) was built, and the resulting reconstruction of ancient philosophical opinion remains the principal indirect access to many lost doctrines.
