It has been sold as science although there is nothing scientific about it. Psychologists do not prove a truth and use proven truths to establish other truths. For instance, Sigmund Freud admitted to having childhood lust for his mother and contempt for his father. His psychosexual lunatical teachings don't reflect all man but he has implied his experience to the motivations of everyone. This shows beyond doubt that it is not a science, because science established truth and builds upon it.
Psychology has no established soundly proven building blocks whatsoever.
In addition to being falsely called science, there are more problems that tie in with our Satanism theme. We are Christians who are psychologists but at the present time there is no acceptable Christian psychology that is markedly different from non-Christian psychology. His being a Protestant offers little justification for acceptance when you examine his extreme involvement in the occult. He delved deeply into the occult, practiced necromancy, and had daily contact with disembodies spirits, which he called archetypes. Just prior to that experience he wrote a fantasy of his soul flying away.
