Let me quote from a letter about Spy in the Hose of Love by Felix Pollak that the author included in her published diary:
"This novel's whole theme must be anathema in a country that, despite its hectic overcompensations, is still laboring under the Puritan strain; for even in the sexiest novels produced here, sex is always treated functionally; a recurrent need leading to recurrent acts, to concessions, whether deplored or affirmed, to natural functions that must be fulfilled so that they can be forgotten and make room for higher things. While in your books, and most clearly in Spy, sex is exposed as the ever present life force, the life of the senses as all-pervading. Eros, sensuality are shown as the spark plugs that set the whole machinery in motion, as the source, the spring, the key, the Mother in the Goethe sense. Unity in manifoldness, no tortuous and artificial duality, no Christian rift between mind and body, no sterile divorce of emotion from reason, but emotion and reason inseparably mated and molded together as effect and cause; instincts, drives seen as what they are: the wire pullers of even the most rational thought processes. The tremendous hidden portion of the tiny iceberg visible above the waters."
This above author sees clearly why these books were not popular when first published. They are written from a fusion of literature with psychoanalysis that did not begin to reach America until the 1960s. Consciousness is only a small human addition to a predominantly mammalian mind. Anais was faithful to pure art and to the future.
