 The second main account, stemming from Aristotle, had been taken over and made Christian by Thomas  Aquinas.[52]  In this account the soul was, though incorporeal, not simply a separate bit attached to the body, but was the form of the individual animal in question, whether human or not. Aquinas presented arguments to show that human souls were subsistent in view of various capacities they had, and proceeded from there to argue for the possibility of the continuing existence of human souls in the absence of the body. He was, however, clear that the human person (even when the person in question was Christ in human form) was not merely a soul with an attached body, but was the body informed by the soul: if your soul alone were to survive death you would not. Bodily resurrection is essential to the survival and immortality of humans.
