The first consideration which guides our choice and inclination is age. In general we accept the age from the years when menstruation begins to those when it ceases, yet we give the decided preference to the period from the eighteenth to the twenty‐eighth year. Outside of those years, on the other hand, no woman can attract us: an old woman, _i.e._, one who no longer menstruates, excites our aversion. Youth without beauty has still always attraction; beauty without youth has none. Clearly the unconscious end which guides us here is the possibility of reproduction in general: therefore every individual loses attraction for the opposite sex in proportion as he or she is removed from the fittest period for begetting or conceiving. The second consideration is that of health. Acute diseases only temporarily disturb us, chronic diseases or cachexia repel us, because they are transmitted to the child. The third consideration is the skeleton, because it is the basis of the type of the species. Next to age and disease nothing repels us so much as a deformed figure; even the most beautiful face cannot atone for it; on the contrary, even the ugliest face when accompanied by a straight figure is unquestionably preferred. Further, we feel every disproportion of the skeleton most strongly; for example, a stunted, dumpy, short‐boned figure, and many such; also a halting gait, where it is not the result of an extraneous accident. On the other hand, a strikingly beautiful figure can make up for all defects: it enchants us. Here also comes in the great value which all attach to the smallness of the feet: it depends upon the fact that they are an essential characteristic of the species, for no animal has the tarsus and the metatarsus taken together so small as man, which accords with his upright walk; he is a plantigrade. Accordingly Jesus Sirach also says (xxvi. 23, according to the revised translation by Kraus): “A woman with a straight figure and beautiful feet is like columns of gold in sockets of silver.” The teeth also are important; because they are essential for nourishment and quite specially hereditary. The fourth consideration is a certain fulness of flesh; thus a predominance of the vegetative function, of plasticity; because this promises abundant nourishment for the fœtus; hence great leanness repels us in a striking degree. A full female bosom exerts an exceptional charm upon the male sex; because, standing in direct connection with the female functions of propagation, it promises abundant nourishment to the new‐born child. On the other hand, excessively fat women excite our disgust: the cause is that this indicates atrophy of the uterus, thus barrenness; which is not known by the head, but by instinct. The last consideration of all is the beauty of the face. Here also before everything else the bones are considered; therefore we look principally for a beautiful nose, and a short turned‐up nose spoils everything. A
