A direct transposition would therefore be without value. In order to make investigations, a radical metamorphosis is an indispensable condition. The soul must be separated from its earthly clothing and pass through all the transformations which commence with natural death. In order to return here, this person must again go through the same processes in reverse order. At his re-birth upon earth he would not, in all probability, differ from other people. He would know as much or as little as we do. But even if we assume the improbable and imagine that this person returned to us with the memory of all he had lived through and that he tried to relate his impressions and experiences, such a report would be of no use because it would deal with ideas and conceptions entirely incomprehensible to us. The explanation of this is that man is unable to comprehend things and phenomena which have not acted upon his present organs. If we take pains to analyze our boldest and most unrealistic fancies, we will find that their substance and ingredients are only greatly enlarged or reduced images of an already experienced reality. We have never possessed that man’s higher senses, never experienced the things which those higher faculties are able to grasp, and we are therefore not in a position to form any idea whatever about such a world. His speech would sound like a foreign language that we could not possibly ever learn to understand. Only in case the person in question could adapt himself to our present way of thinking and understanding, would such a revelation be of any importance. But then again the question arises, what confidence could we have in this man who pretended to possess knowledge about things entirely concealed from us? We have no means of verifying the information thus received. It must be taken in good faith, and so the gates to doubt would again be thrown open. If someone returned, then, little or nothing would be gained. In this, as in other cases, there is no royal road to truth. Only a painstaking research will lead to the goal, if indeed it can ever be attained.
