"Another and perhaps even more widely spread misconception is, that death is a plunge into the great unknown—that nothing can ever be learnt with any certainty as to the states into which man passes when he leaves this physical plane. Certainly various religious sects profess to give exceedingly precise information as to these states, yet to the vast majority of their followers there seems to be a sense of absolute unreality about it all; at any rate, they neither act nor speak as though they really believed it. And indeed, in the case of most of these sects the information given is so wildly inaccurate that even if it were believed it is very doubtful whether it would not produce more harm than good."
