Chrysippus Quotes
When through the power of sight we see white, that which comes about in the soul through the act of seeing is a modification. And on the basis of this modification, we are able to say that the white which is affecting us exists.

Chrysippus of Soli (/kraɪˈsɪpəs, krɪ-/; Greek: Χρύσιππος ὁ Σολεύς, Chrysippos ho Soleus; c. 279 – c. 206 BC) was a Greek Stoic philosopher. He was a native of Soli, Cilicia, but moved to Athens as a young man, where he became a pupil of Cleanthes in the Stoic school. When Cleanthes died, around 230 BC, Chrysippus became the third head of the school. A prolific writer, Chrysippus expanded the fundamental doctrines of Zeno of Citium, the founder of the school, which earned him the title of Second Founder of Stoicism.
