4. The Rise of Spiritualism. The Need for the Science of the Spirit

Humanity had become accustomed to recognize as true only what had been verified by means of investigation in a laboratory or clinic. Now, in the same way, through external operations following precisely the pattern of the natural scientific method, a method was elaborated that should give manifest proof of the spirit. Important results have undoubtedly been attained on this path. In addition, of course, there has been a good deal of charlatanism and swindling. Indeed, we know that certain learned men and scientists who must be taken seriously have devoted themselves to these matters because they have felt it necessary to show man, who must otherwise fall prey to materialism, that a spiritual world exists, surrounding us just as does what we see with our eyes and grasp with our hands. So, in the course of human evolution after the middle of the nineteenth century, we have these efforts to make men understand that there is a spiritual world around us just as there is a world that we perceive with our senses.
