“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (1896–1948)
“Whereas Freud was for the most part concerned with the morbid effects of unconscious repression, Jung was more interested in the manifestations of unconscious expression, first in the dream and eventually in all the more orderly products of religion and art and morals.”
