Greek philosophers
Diogenes of Seleucia was a Greek philosopher who was born in 240 BC in Seleucia (in Babylonia) and died in 150 BC. He was a representative of the Stoic school and a pupil of Chrysippus of Soloia.
In 156 BC, Diogenes came to Rome together with Critolaus of Fasélida and Carneades, and here he helped to popularize Stoicism among the Roman aristocracy. He also wrote many works dealing with dialectics, voice, nobility, and the law. He also dealt with astrology and divination.
He taught that the soul resides in the heart and that the life of the soul is conditioned by the circulation of the blood. He considered the human voice to be a gust of air.
His most important disciple was Panaitios.
