Arcesilaus was a Greek Hellenistic philosopher. He was the founder of Academic Skepticism and what is variously called the Second or Middle or New Academy – the phase of the Platonic Academy in which it embraced philosophical skepticism.
Arcesilaus and Carneades
Hellenistic philosophy is Ancient Greek philosophy corresponding to the Hellenistic period in Ancient Greece, from the death of Alexander the Great in 323 BC to the Battle of Actium in 31 BC. The dominant schools of this period were the Stoics, the Epicureans and the Skeptics.
Chrysippus, the third leader of the Stoic school, wrote over 300 books on logic. His works were lost, but an outline of his logical system can be reconstructed from fragments and testimony.
In Stoic physics, the universe begins and ends in a divine artisan-fire.
