Among animals, which have but a low degree of intelligence, instinct is at its height, and works well. Among savages, still incapable of much intellectual development, instinct holds large place. The mother beast can and does take all the care of her young by instinct; the mother savage, nearly all, supplemented by the tribal traditions, the educative influences of association, and some direct instruction. As humanity advances, growing more complex and varied, and as human intelligence advances to keep pace with new functions and new needs, instinct decreases in value. The human creature prospers and progresses not by virtue of his animal instinct, but by the wisdom and force of a cultivated intelligence and will, with which to guide his action and to control and modify the very instincts which used to govern him. The human female, denied the enlarged activities which have developed intelligence in man, denied the education of the will which only comes by freedom and power, has maintained the rudimentary forces of instinct to the present day. With her extreme modification to sex, this faculty of instinct runs mainly along sex-lines, and finds fullest vent in the processes of maternity, where it has held unbroken sway. So the children of humanity are born into the arms of an endless succession of untrained mothers, who bring to the care and teaching of their children neither education for that wonderful work nor experience therein: they bring merely the intense accumulated force of a brute instinct,—the blind devoted passion of the mother for the child. Maternal love is an enormous force, but force needs direction. Simply to love the child does not serve him unless specific acts of service express this love. What these acts of service are and how they are performed make or mar his life forever. Observe the futility of unaided maternal love and instinct in the simple act of feeding the child. Belonging to order mammalia, the human mother has an instinctive desire to suckle her young. (Some ultra-civilized have lost even that.) But this instinct has not taught her such habits of life as insure her ability to fulfil this natural function. Failing in the natural method, of what further use is instinct in the nourishment of the child? Can maternal instinct discriminate between Marrow’s Food and Bridge’s Food, Hayrick’s Food and Pestle’s Food, Pennywhistle’s Sterilized Milk, and all the other infants’ foods which are prepared and put upon the market by—men! These are not prepared by instinct, maternal or paternal, but by chemical analysis and physiological study; and their effect is observed and the diet varied by physicians, who do not do their work by instinct, either.
