2927. THAT SPIRITS, ALTHOUGH NOT INSTRUCTED DURING LIFE, APPROPRIATED TO THEMSELVES ALL THE SCIENCE OF MAN, AS IF THEY [HAD BEEN] INSTRUCTED. ((I will merely mention) for example [that] when sometimes I have made arithmetical calculations in [ex] the head, as it is said, then spirits could [do] it of themselves, as was made known by experience. In like manner as respects the other sciences, whatever they are, man is only expert by practice [callet] [but] a spirit possesses them as his own, although he may have heard nothing thereof in life.
