 The doctrine of knowledge by recollection offers a solution. When we inquire into the truth of a theorem, we both do and do not already know it. We have knowledge in the form of a memory gained from our soul’s knowledge of the theorem prior to its union with our body. We also lack some knowledge because, in our soul’s unification with the body, it has forgotten the knowledge and now needs to recollect it. Thus, learning the theorem allows us, in effect, to recall what we already know.
