STILPOMegara, 320 B.C.
Distinguished philosopher, who taught both at the Megarian School and in Athens. The time of his life and activity is determined only indirectly, in the sense that he was a contemporary of Demetrius Poliorkitos and Ptolemy the Savior (3rd - 2nd century BC). He recognized the existence of only one absolute and immovable being and rejected the multiplicity of beings. Consequently, he also rejected polytheism. Stilpon considers the apathy of the soul to be the highest good. None of his writings have survived.
