The strength of reactions to Freud's theories may be attributed to the sanctity and yet obscenity of the subject of sex and Freud's presentation of this subject which the author calls 'extravagant'. Freud's art is the 'poetry of psychic processes'. To emphasize the artist in Freud is not to diminish his significance for science, but includes a recognition as one of the greatest masters in thought. Freud preserved the correct attitude of the conventional physician but in a simple and precise and detailed manner he described the sex phenomena presented by his patients without attenuation or apology. Doing so, he supplied an immense emphasis to the general recognition and acceptance of the place of sex in life. With special delight, Havelock Ellis states that it was he who published the first book in the English language in which Freud's name was introduced and his work expounded. One of the terms which Freud accepted from Havelock Ellis is the word 'auto-erotism', although Freud used it somewhat differently.
