1.—“Action repeated tends to rhythmic course.”
“Other and wider muscular actions, partly internal and partly external, also take place in a rhythmical manner in relation with systemic conditions. The motions of the diaphragm and of the thoracic and abdominal walls, in connection with respiration, belong to this category. These movements, though in the main independent of will, are capable of being very considerably modified thereby, and while they are most frequently unheeded, they have a very recognisable accompaniment of feeling when attention is distinctly turned to them.... The contraction of oviducts or of the womb, as well as the movements concerned in respiration, also had their beginnings in forms of life whose advent is now buried in the immeasurable past.”—Dr. H. C. Bastian (“The Brain as an Organ of Mind,” p. 220).
4.—“Till habit bred hereditary trace.”
“Let it be granted that the more frequently psychical states occur in a certain order, the stronger becomes their tendency to cohere in that order, until they at last become inseparable; let it be granted that this tendency is, in however slight a degree, inherited, so that if the experiences remain the same, each successive generation bequeaths a somewhat increased tendency, and it follows that, in cases like the one described, there must eventually result an automatic connection of nervous actions, corresponding to the external relations perpetually experienced. Similarly, if from some change in the environment of any species its members are frequently brought in contact with a relation having terms a little more involved; if the organisation of the species is so far developed as to be impressible by these terms in close succession, then an inner relation corresponding to this new outer relation will gradually be formed, and will, in the end, become organic. And so on in subsequent stages of progress.”—Herbert Spencer (“Principles of Psychology,” Vol. I., p. 439).
Id.... “I have described the manner in which the hereditary tendencies and instincts arise from habit, induced in the nervous cellules by a sufficient repetition of the same acts.”—Letourneau (“The Evolution of Marriage,” Chap. I.).
Id.... “Ainsi l’évacuation menstruelle une fois introduite dans l’espèce, se sera communiquée par une filiation non interrompue; de sorte qu’on peut dire qu’une femme a maintenant des règles, par la seule raison que sa mère les a eues, comme elle aurait été phthisique peut être, si sa mère l’eût été; il y a plus, elle peut être sujette au flux menstruel, même quoique la cause primitive qui introduisit ce besoin ne subsiste plus en elle.”—Roussel (“Système de la Femme,” p. 134).
Id.... “Il y a eu des auteurs qui ne voulaient pas considérer la menstruation comme une fonction inhérente à la nature de la femme, mais comme une fonction acquise, continuant par l’habitude.”—Raciborski (“Traité de la Menstruation,” p. 17).
Id.... “The ‘set’ of mind, as Professor Tyndall well calls it, whether, as he says, ‘impressed upon the molecules of the brain,’ or conveyed in any other way, is quite as much a human as an animal phenomenon. Perhaps the greater part of those qualities which we call the characteristics of race are nothing else but the ‘set’ of the minds of men transmitted from generation to generation, stronger and more marked when the deeds are repeated, weaker and fainter as they fall into disuse.... Tyndall says: ‘No mother can wash or suckle her baby without having a “set” towards washing and suckling impressed upon the molecules of her brain, and this set, according to the laws of hereditary transmission, is passed on to her daughter. Not only, therefore, does the woman at the present day suffer deflection from intellectual pursuits through her proper motherly instincts, but inherited proclivities act upon her mind like a multiplying galvanometer, to augment indefinitely the amount of the deflection. Tendency is immanent even in spinsters, to warp them from intellect to baby-love.’ (Essay: “Odds and Ends of Alpine Life.”) Thus, if we could, by preaching our pet ideal, or in any other way induce one generation of women to turn to a new pursuit, we should have accomplished a step towards bending all future womanhood in the same direction.”—Frances Power Cobbe (Essay: “The Final Cause of Woman”).
