"SOUL, n. A spiritual entity concerning which there hath been brave disputation. Plato held that those souls which in a previous state of existence (antedating Athens) had obtained the clearest glimpses of eternal truth entered into the bodies of persons who became philosophers. Plato himself was a philosopher. The souls that had least contemplated divine truth animated the bodies of usurpers and despots. Dionysius I, who had threatened to decapitate the broad-browed philosopher, was a usurper and a despot. Plato, doubtless, was not the first to construct a system of philosophy that could be quoted against his enemies; certainly he was not the last."
