Franklin Merrell-Wolff continues this series by outlining the second postulate of Jungian psychology, which is Jung’s conception of psychological typology. Wolff describes the attitudes of extraversion and introversion, and defines the four primary functions of thinking, feeling, sensation, and intuition. He turns to the complexities of type psychology when other factors are taken into consideration, and then examines a few of the consequences entailed by psychological typology for politics, therapy, and diet. He goes on to summarize the typology developed by Dr. Sheldon, who developed temperamental types based upon physiological type; namely, the endomorphic, mesomorphic, and ectomorphic. Next, Wolff gives an account of Celtic and Germanic history and discusses the influence this historical development had on the formulation of the Grail myth and the masculine psychology of Western civilization in Europe and North America. He discusses the superposition of Christianity upon the barbaric peoples of Europe at that time and points out that this barbarism could only be transformed or redeemed by applying the principle of determination by force. He goes on to question the validity of the Grail myth for all psychological types, for those who are not of Celtic-Germanic descent, and for those not conditioned by the principle of determination by force. He then cites Aurobindo’s essay on Heraclitus in which it is pointed out that humanity is evolving beyond determination by the principle of force, through determination by the principle of reason, and toward determination by the principle of ananda.
