Some notice must be taken of sundry accounts of martyrs' visions, because you have thought proper to derive some of your evidence therefrom. St. Perpetua, for instance, seemed to herself in dreams to be wrestling with an Egyptian, after being changed into a man. Now, who can doubt that it was her soul in that apparent bodily form, not her body, which, of course, remained in her own sex as a woman, and lay on the bed with her senses steeped in sleep, whilst her soul was struggling in the similitude of a man's body? What have you to say to this? Was that male likeness a veritable body, or was it no body at all, although possessing the appearance of a body? Choose your alternative. If it was a body, why did it not maintain its sexual integrity? For in that woman's flesh were found no virile functions of generation, whence by any such process as that which you call congelation could be moulded this similitude of a man's body. We will conclude then, if you please, that, as her body was still alive while she slept, notwithstanding the wrestling of her soul, she remained in her own natural sex, enclosed, of course, in all her proper limbs which belong to her in her living state, and was still in possession of that bodily shape and the lineaments of which she had been originally formed. She had not resigned, as she would by death, her joints and limbs; nor had she withdrawn from the transposing power, which arises from the operation of the power of death, any of her members which had already received their fixed form. Whence, then, did her soul get that virile body in which she seemed to wrestle with her adversary? If, however, this [male likeness] was not a body, although such a semblance of one as admitted the sensation in it of a real struggle or a real joy, do you not by this time see, as far as may be, that there can be in the soul a certain resemblance of a bodily substance, while the soul is not itself a body?
