Why can’t I see behind my head, if it is my soul’s attention that makes the difference and not the way the objects in front of me are affecting my eyes? Olivi’s solution would seem to be that our bodies do restrict the scope of our awareness in this life. Remember that the power of sense is in the lower soul, and thus tied to the body. In the afterlife we will not be so restricted, but will have a more general and unimpeded apprehension of things.
