In this postcard, Jung declines an invitation to submit articles to a journal Smith Ely Jelliffe edited because American medical colleagues find his writing hard to understand and consider him a �mystic.� The charge that Jung�s work was compromised by mysticism stemmed from the value he placed on mythology and symbols as well as his statements questioning the all-sufficiency of reason and science. Jung defended himself by observing that �if you call me an occultist because I am seriously investigating religious, mythological, and philosophical fantasies. . . . then you are bound to diagnose Freud as a sexual pervert since his is doing likewise with sexual fantasies.�
