By a misuse of science man has come to believe in a closed system of cause and effect that has no place for the supernatural.  Everything must be explained by natural causes without any outside interference.  Only the scientifically provable is real.  So thinking today is in a tightly closed box.

But people cannot happily live in such a confined space.  They need the supernatural.  But having rejected the supernaturally good, i.e. God, they are reaching out to the supernaturally evil.  Hence the recent rise of black magic, seances, ouija boards, "Man, Myth and Magic", etc.  All this points to man's deep need of something above and beyond himself.
