ditions, can do. The same is true of what geniuses, or so-called arithmetical prodigies, can do as compared with what ordinary men can do. And that a man is a genius or a calculating prodigy is shown by what he does do, not the reality of what he does by his being a genius or prodigy. This holds equally as regards a medium and his levitations or other paranormal phenomena. The crucial question is therefore not whether paranormal levitations are frequent, or happen to ordinary people, but whether they ever actually have occurred. If even only once, this is enough to show that some force as yet not understood by us exists.
Thus, the philosophically open-minded, critically rational part of the dissociated personality to which I have confessed finds, as standing in the way of acceptance of the clear cut testimony quoted, little else than the naive tacit assumption that if the knowledge possessed by physicists as of December 1954 cannot explain levitation, then levitation is impossible!
