All the ancient philosophers, pagans and Christians alike, agreed that death is the separation of a soul and a body. While there was much disagreement on the precise relationship between a being and his soul, as well as what sort of thing they took a soul to be, it is the agreement among the philosophers rather than their differences that calls for critical attention. Jonathan Barnes examines why ancient philosophers believed that beings were composed of two parts, the divorce of which is death.
