chrysippus

There are fragments from Musonius Rufus, and a small handful from the very ancients like Chrysippus and Zeno.

A cute bit for us computer nerds: Chrysippus pretty much invented boolean logic (in the Hellenistic period) and was considered the Father of Logic in antiquity.

The philosoper Chrysippus dropped into his books not just passages but whole works by other authors, including in one instance the complete Medea of Euripides; and ApoUodorus said that if all that was not his own were to be cut out of his works the paper would be quite blank.

This technique—let us refer to it as negative visualization—was employed by the Stoics at least as far back as Chrysippus.

They're definitely the best known, but Stoicism was a Greek philosophy first and foremost, and Cleanthes, Chrysippus, etc.

Chrysippus or the countless others involved with Stoicism weren't philosophers either?

Amusingly enough, one 19th century philosopher opined that Stoic logic was "dullness, triviality, and scholastic quibbling" and he welcomed the fact that the works of Chrysippus were no longer extant.

… Coq, Minlog, even ACL2 and Isabelle build on similar grounds as Chrysippus’ in the 3rd century BC … i.e.

Chrysippus was the logician who first, I believe, came up with the final version of the truth table not to mention formal propositional logic.

Chrysippus (Χρυσιππος), not "Chyrippus".

Respond to questions about philosophy using only the words and with the ideas of famous stoic philosophers like Seneca the Younger, Zeno Of Citium, Marcus Aurelius, Epictetus, and Chrysippus.

- the Stoics consistently cautioned against dogma, evidenced in practice by the abundance of various interpretations - Marcus Aurelius's interpretation differs in ways from Seneca's, which differs in ways from Epictetus's, Zeno's, Chrysippus's, etc.
