52 Each, then, is supported by each. But belief in the resurrection is inferred most clearly on three grounds, in which all are included. These are reason, analogy from universal example, and the evidence of what has happened, since many have risen. Reason is clear. For since the whole course of our life consists in the union of body and soul, and the resurrection brings with it either the reward of good works, or the punishment of wicked ones, it is necessary that the body, whose actions are weighed, rise again. For how shall the soul be summoned to judgment without the body, when account has to be rendered of the companionship of itself and the body?
