Note 147 — PHILOSOPHICAL TERMINOLOGY.
Reading edition
Cicero says: “Fuit jam a Platone accepta philosophandi ratio triplex: una de vita et moribus; altera de natura et rebus occultis; tertia de disserendo, et quid verum, quid falsum, quid rectum in oratione, pravumque, quid consentiens, quid repugnans, judicando” (Acad. lib. i. 6). This division is still recognizable in our modern logic, metaphysics, and ethics.
