=Smell.= In animals the sense of smell plays probably a more important part than the sense of sight. In man the olfactory sense has become more negative and protective than positive. It enables him to avoid rather than to locate certain objects. This partial atrophy of the positive olfactory capacities is undoubtedly due to the progress of hygiene and cleanliness in human life. The child whose mother is carefully shampooed and bathed will not consider strong odors emanating from hair or arm pits as a symbol of safety. On the contrary, they will be something foreign to him, hence suggestive of danger. In ancient times, bodily odors were frequently mentioned as love stimulants. The Homeric poems, the Song of Songs, the Kamasutra and other Hindoo erotic works, the Arabian Perfumed Garden and even in more recent times, poems like Herrick's "Julia's Sweat," extolled strong body odors which at the present day not only are deemed offensive but cannot be mentioned except in medical writings. The modern bathroom has exiled olfactory allusions from literature. Odors can be, not only fetishes but very often powerful antifetishes. This is partly due to a repression of the child's interest in his excretions which later burst forth in the use of perfume by women, smoking by men and women. Cigar smoking for instance supplies an outlet for a number of childish polymorphous perversions, to use Freud's expression. In this case as in many others, violent repugnance to odors good or bad in adulthood may be traced to a morbid craving for them in childhood. =The Sense of Taste= is not very important in love, altho some experienced lovers detect a distinct flavor in the skin of various parts of one woman's skin, cheeks, arms, etc. Taste observed in purely nutritional activities reveals constantly its unconscious infantile origin. However completely we may have been weaned, we constantly pay a tribute of appreciation to our first food. The exaggerated and unjustified importance we attribute to milk in the diet of adults, the way in which we designate a white complexion as "milky" or "creamy," and in which we praise many tender foods by stating that they are "like cream" or "melt in our mouth" illustrates, together with the popularity of breast fetishism, the influence which infantile gustatory impressions have made on all of us. =Touch= is probably as important as sight for physico-chemical reasons. All animals seem to enjoy the close contact of other animals of their own species. Even on very warm days, puppies, kittens and young birds derive a very great comfort from being huddled together in kennel, basket or nest. There are two reasons for that craving for contact. The safest period of our life which our automatic nerves remember is the fetal period during which the contact of the child with the womb is constant and in perfect relation to the fetus' growth.
