The mystical trend of our time, which shows itself particularly in the rampant growth of the so-called Theosophy and Spiritualism, is for me no more than a symptom of weakness and confusion. Since our inner experiences consist of reproductions and combinations of sensory impressions, the concept of a soul without a body seem to me to be empty and devoid of meaning.
