Accordingly woman has one instinct more than man; and the ganglion system is also much more developed in the woman. That man has fewer instincts than the brutes and that even these few can be easily led astray, may be explained from the great preponderance of the brain in his case.

Context

“It seems to arise from the fact that the nourishment of the embryo sometimes requires a special or definite modification of the blood which flows to it, upon which the food which produces such a modification at once presents itself to the pregnant woman as an object of ardent longing, thus here also an illusion arises. Accordingly woman has one instinct more than man; and the ganglion system is also much more developed in the woman. That man has fewer instincts than the brutes and that even these few can be easily led astray, may be explained from the great preponderance of the brain in his case. The sense of beauty which instinctively guides the selection for the satisfaction of sexual passion is led astray when it degenerates into the tendency to pederasty; analogous to the fact that the blue-bottle (Musca vomitoria ) , instead of depositing its eggs, according to instinct, in putrefying flesh, lays them in the blossom of the Arum dracunculus , deceived by the cadaverous smell of this plant.
