This “state in which the mind continues calm and strong, undisturbed by … any … emotion” Democritus called athambia (inability to be astonished or frightened) and, according to Stobaeus (DK 68A67), ataraxia (inability to become agitated or upset), the term which descended through the two Democritean lineages—the dogmatic or Epicurean and the critical or Pyrrhonist. It is related closely to the apatheia (nonemotionality) taught by the Cynics and seems substantially the same as the condition which the Prajñaparamita literature attributes to one who knows emptiness: One who is convinced of the emptiness of everything is not captivated by worldly dharmas, because he does not lean on them.
