that much tabooed
subject of sexuality. Unfortunately, as Hitschmann[6] says, physicians
in their personal relations to the sexual life have not been given any
preference over the rest of the children of men and many of them stand
under the ban of that combination of prudery and lust which governs the
attitude of most cultivated people in sexual matters. Especially
unsavory appears to most people Freud's theory of infantile sexuality, a
subject which has heretofore been looked upon chiefly from a moralistic
standpoint, and was spoken of by others merely as odd or as a frightful
example of precocious depravity. It is somewhat strange that of all the
frightful depravities, if we wish to call it so--inherent in man, of the
marked criminalistic components universally present in man which
psychoanalytic studies have revealed--the sex depravity should have
provoked the most fanatic attacks. Indeed to those who are accustomed to
look at man with the psychoanalytic eye, Rochefoucauld's incisive
statement does not at all sound strange. He said, "I have never seen the
soul of a bad man; but I had a glimpse at the soul of a good man; I was
shocked." I therefore crave the indulgence of those of you who are not
familiar with psychoanalytic literature for what I am about to quote
briefly from Freud's theories on the sexual instinct in man.

Freud lays special stress upon infantile sexuality as it is manifested
in the suckling and in the child. The infant brings with it into the
world the germ of sexuality, which is, however, extremely difficult of
comprehension since at this stage the sexual feelings are not directed
towards other persons but are gratified on the child's own body in a
manner which Havelock Ellis has termed "autoerotic." This autoerotic
gratification is gained through erogenous zones, that is, certain areas
of the body which are peculiarly sensitized to sexual excitations. Among
these erogenous zones may be mentioned the mouth, lips, tongue, anal
region, the neck of the bladder as well as various skin areas and sense
organs. Already in 1879, Lindner, a Hungarian pediatrist, devoted a
penetrating study to the sucking or pleasure-sucking of the child. Freud
emphasizes that the suckling enjoys sexual pleasure, in the taking of
nourishment, which it ever after seeks to procure by sucking independent
of taking food. To many it may occasion surprise to learn that sucking
is exhibited independently of its relation to the hun
