Three hundred years after Epicurus, Lucretius in his epic poem "On the Nature of Things" would depict him as the hero who crushed the monster Religion through educating the people in what was possible in the atoms and what was "not" possible in the atoms. However, Epicurus expressed a non-aggressive attitude characterized by his statement: "The man who best knows how to meet external threats makes into one family all the creatures he can; and those he can not, he at any rate does not treat as aliens; and where he finds even this impossible, he avoids all dealings, and, so far as is advantageous, excludes them from his life."
