In the course of my stay in Paris in 1903 I had long talks with Baron Alphonse, the septuagenarian head of the Rothschild house. Our conversation mostly revolved around the preoccupation with the occult and the mystic which had taken root at the Russian Court, this being, in the Baron's opinion, a bad symptom. He repeatedly returned to this subject. History shows, he pointed out, that great events, especially of an internal nature, were always and everywhere preceded by the prevalence of a bizarre mysticism at the court of the ruler.

The greater part of superstition signifies fear of impending evil, and he who has frequently wished evil to others, but because of a good bringing-up has repressed the same into the unconscious, will be particularly apt to expect punishment for such unconscious evil in the form of a mis­fortune threatening him from without.
