Note 16 — Chapter V · LOGIC OF THE STOICS.
Oswald J. (Oswald Joseph) Reichel translation
The statements of Zeno and Cleanthes, for instance, in reference to φαντασία, prove that these Stoics deduced their theory of knowledge from general principles respecting notions. They therefore started from the data supplied by the senses. A passage in Zeno, explaining the relations of various forms of knowledge, shows that even Zeno required progress to be from perception to conception and knowledge, and that he distinguished these states only by the varying strength of conviction which they produced. ↑
