Pemenang hadiah Nobel, Dr. Alexis Carrel, telah menjelaskan perbedaan biologis antara laki-lai dan perempuan dalam bukunya “Man, the Unknown”. Dia menyimpulkan dengan analisa sebagai berikut:
Women differs profoundly from Man
“The Difference existing between man and woman do not come from particular form of sexual organs, the presence of the uterus, from gestation, or from the mode of education. They are of a more fundamental impregnation of the entire organism with specific chemical substances secreted by the ovary. Ignorance of these fundamental facts has led promoters of feminims to believe that both sexes shoud have the same education, the same powers and the same responsibiliteis. In reality woman differs profoundly from man. Every one of the cells of her body bears the marks of her sex. The same is true of her organs and, above all, of her nervous system. Physiological laws are as inexorable as those of the sidereal world. They cannot be replaced by human wishes. We are obliged to accept them just as they are. Women shoud develop their aptitudes in accordance with their own nature, without trying to imitate the males. Their part in progress of civilization is higher than that of men. They should not abandon their specific functions.” (Dr. Alexix, Carrel; Man, The Unknown; New York, 1499; p.91)
