Zeno Case

Zeno of citium did a lot of changes in ancient philosophy without him we wouldn't be where we are now. He was a son of merchant and a merchant himself. Zeno was a Hellenistic philosopher born in the 3rd century BC in the town of Citium. Zeno might have had Phoenician ancestry. Unfortunately none of his original writings have survived. We know his work from the accounts of others. Ofcource there are a lot of rumors, myths, and excerpts. One of the major sources was written by Diogenes Laertius who wrote "The Lives and opinions of Eminent Philosophers".

They denied the metaphysical reality of concepts, and instead held that the criterion of truth lies in sensation. The truth was achieved not through thought, but through feeling. The fundamental proposition of Stoic physics is that "nothing incorporeal exists." They were highly materialistic, as is evident by their sensation-based doctrine of knowledge. The stoics, who placed knowledge in physical sensation, believed reality was matter. They did not agree with Plato's concept that the reality had some ideal form.
