Hellenistic-era philosophers

Archimedes of Syracuse ( ; ) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the city of Syracuse in Sicily. Although few details of his life are known, based on his surviving work, he is considered one of the leading scientists in classical antiquity, and one of the greatest mathematicians of all time. Archimedes anticipated modern calculus and analysis by applying the concept of the infinitesimals and the method of exhaustion to derive and rigorously prove many geometrical theorems, including the area of a circle, the surface area and volume of a sphere

Stilpo or Stilpon (, Stílpōn; c. 360 – c. 280 BC), in Latin sources also Stilbo or Stilbon, was a Greek philosopher of the Megarian school. He was a contemporary of Theophrastus, Diodorus Cronus, and Crates of Thebes. None of his writings survive, but he is described in the writings of others as being interested in logic and dialectic, and he argued that the universal is fundamentally separated from the individual and concrete. His ethical teachings approached that of the Cynics and Stoics. His most important followers were Pyrrho, the founder of Pyrrhonism, and Zeno of Citium, the founder of

Euhemerus (; also spelled Euemeros or Evemerus; Euhēmeros, "happy; prosperous"; late fourth century BC) was a Greek mythographer at the court of Cassander, the king of Macedon. Euhemerus' birthplace is disputed, with Messina in Sicily as the most probable location, while others suggest Chios or Tegea.

Anaxarchus (; ; c. 380 – c. 320 BC) was a Greek philosopher of the school of Democritus. Together with Pyrrho, he accompanied Alexander the Great into Asia. The reports of his philosophical views suggest that he was a forerunner of the Greek skeptics.

Anniceris (; fl. 300 BC) was a Cyrenaic philosopher. He argued that pleasure is achieved through individual acts of gratification which are sought for the pleasure that they produce, but he also laid great emphasis on the love of family, country, friendship and gratitude, which provide pleasure even when they demand sacrifice.

Cercidas ( Kerkidas; fl. 3rd century BC) was a poet, Cynic philosopher, and legislator for his native city Megalopolis. A papyrus roll containing fragments from seven of his Cynic poems was discovered at Oxyrhynchus in 1906.

Panthoides (; fl. c. 275 BC) was a dialectician and philosopher of the Megarian school.
