Epicurus

Epicurus (341-270 BC) was a Greek philosopher who believed that the purpose of philosophy was to find the key to a happy and peaceful life, one free from fear and pain. He was born on the Aegean island of Samos and studied with the teacher Pamphilus. After completing a period of military service, he became a teacher in Mytilene. He founded a school in Lampsacus and then one in Athens in 306 BC, where he lives for the remainder of his life. He aided the study of science through his advocacy of the idea that nothing could be believed unless it was tested and observed.
