Posidonius (c.135–51 BCE) was a Greek philosopher, historian, astronomer, and geographer, regarded as one of the most learned figures of his time and a leading Stoic thinker.
Born in Apamea, Syria, he studied Stoicism under Panaetius in Athens before settling in Rhodes, where he established a renowned school attracting scholars from across the Mediterranean.
A polymath, Posidonius contributed to philosophy, natural sciences, and geography. His extensive travels provided scientific data and cultural insights that shaped his writings. His philosophy blended Stoicism with elements of Plato and Aristotle, making him a key figure in Middle Stoicism.
Though none of his works survive in full, Cicero, Strabo, and Seneca referenced his ideas. He wrote on history, ethics, and natural phenomena. His known works include Histories (covering events from 146 BCE) and treatises on astronomy, geography, and meteorology. He attempted to calculate Earth’s circumference and studied the moon’s influence on tides.

Riches are a cause of evil, not because, of themselves, they do any evil, but because they goad men on to evil.
