ABSTRACT
Upon Arcesilaus's death , the headship of the Academy passed to Lacydes of Cyrene. He is said to have died of alcohol poisoning Lacydes developed an elaborate system of locking his storeroom door, sealing it, then posting the signet-ring through it; his slaves observed and copied it, sealing up the door after them after they had taken what they wanted. Carneades is one of the great figures in the history of philosophy. Eusebius reports that Carneades took up the succession, and established a third Academy. The Stoics make claims for the cataleptic impression which necessarily go beyond what is given in perception; for precisely this reason the Academics are committed to the view that we can never know for certain that a particular impression is cataleptic, and hence it cannot wear its cataleptic nature on its sleeve.
