On the Role of Signs in Epicurus’ Legal Theory

Abstract

Epicurus holds, in Key Doctrine 31, that what is just according to nature is a súmbolon or sign of the interest there is in neither harming one another nor being harmed. Certain readings of this maxim equivocate this legal sign with other signs found in nature, thereby failing to give sufficient weight to the role of reciprocity in its production. Other readings simply import a legal sense from outside of Epicurean doctrine, thereby failing to explain what makes Epicurean súmbola legal. A final set of readings attempt to find a legal rule as a kind of innate concept or Kantian ‘scheme’. This article identifies new sources for understanding súmbolon, drawn principally but not exclusively from Aristotle’s Eudemian Ethics. This article offers an original argument that Epicurus adopts Aristotle’s’ image of the tally stick (symbolon) as a meeting of often divergent interests which constitutes something new and particularly valuable to the Epicurean: friendship.
