However, in an optical turnstile manner, and without any appreciable attentional control at that, he is in un-reality being expertly scanned, circumscriptively
watched over from all angles, from all sides and heights.
Buridan's broad strategy for solving this problem is to appeal to the medieval distinction between being definitively in a place and circumscriptively in a place.(27) According to this distinction, the intellective soul of a human being would be said to inhere definitively but not circumscriptively in its body, that is, such that it is present to its body whole in whole and whole in part, rather than whole in whole and part in part.(28) The latter is the mode of inherence exhibited by material forms such as the sensitive souls of nonhuman animals and the vegetative souls of plants.
(31) For Buridan, this follows from the assumption that indivisible animate forms such as the intellective soul are definitively rather than circumscriptively present in the bodies in which they inhere.
