468. CONCERNING THE SPHERE BETWEEN THINGS OPPOSITE From very much experience I have learnt that when souls and spirits are once persuaded of a truth, for the most part and almost always, they are carried away into things contrary, and thus into doubts concerning truths. The experience given me in heaven concerning these things is so multiple that it would be tedious to narrate it. The reason of this is that man ought not to be persuaded concerning truth by visible persuasions, thus not by miracles; furthermore, that a great sphere must be acquired, whereby man is rendered flexible, besides many things which are not now given me [to relate]. 1748, Jan. 12.
