Pedagogical Anthropology by Maria Montessori (best novels of all time TXT) 📕

certain ages at which even the strong are weak; and their weakness is of such a nature that it exposes the individual to death.

Now, whenever the phenomenon of mortality occurs it is always an indication of impoverishment in the survivors. For example, of every one person that dies, many persons have been ill who have recovered from their illness; but there are still many others who, although they did not actually fall ill, were weakened even though they passed through the peril unharmed.

In short, for each death, which represents a final disaster, there are many victims. And whenever there is a rise in the phenomenon of mortality in connection with any one age, it is our duty to give special attention to those individuals who are not only weak in themselves, but whom the social causes affecting them tend to weaken still more and push onward toward illness and death. Whenever there are many deaths, there are undoubtedly also many sufferers.

Now, in pedagogy we have no criterion to guide us in this matter of respecting the weaknesses characteristic of the various ages, as, for example, that of early infancy and of the age of puberty.

With the most cruel blindness we punish and discourage the lad who, having reached the age of puberty, no longer makes the progress in his studies that rendered him the brilliant champion during the period of physiological repose in his growth; and instead of regarding this as a psychic indication of a great physiological transformation that it is necessary to protect, we urge on the organism to enforced effort, without even suspecting that, in proportion to the degree of resistance of our pupil, we may be doing our share to induce in him a permanent weakness, or an arrest of development, or disease and death.

Our responsibility as educators is great, because we have the threads of life entrusted to our care; man represents a continuous transition through successive forms, and each following period has been prepared for by the one preceding.

Whenever we have the misfortune to concur in weakening a child, we touch that parabolic line traced in the graphic chart of stature, and standing as an index of the life of the body, and we give it a shock throughout its whole length; it may either be shattered or be brought down to a lower grade.

But the life of an individual does not contain merely that individual alone; the cycle of the stature with its violent period of puberty and the perfect physiological repose corresponding to the years from 25 to 36, or even 45, indicates the eternity of the individual in the species: his maturity for reproduction. Man in his progress through the different levels of height, as indicated on the graphic chart of stature, does not pass through them without reproducing himself, save in exceptional cases; he commences the ascent alone, but in his descent he attains the majesty of a creator who leaves behind him the immortal works of his own creation. Well, even the capacity of normal reproduction, and of begetting a strong species, is related to the normal cycle of life: whoever weakens a child and puts a strain upon the threads of its existence, starts a vibration that will be felt throughout posterity.

The parabolic cycle of stature shows us which is the most favourable period for the reproduction of the species; it is undoubtedly that period that stands at the highest apex of the curve, and at which the organism has reached an almost absolute peace, as if forgetful of itself, in order to provide for its eternity. When it has completed its period of evolution, during which the organism shows that it has not yet matured; and before the commencement of involution, in which period the organism is slowly preparing for departure—that is the moment when man may or rather ought to procreate his species.

Careful forethought not to produce immature or feeble fruit, will form part of the coming man's regard for his posterity. A new moral era is maturing, that is giving birth to a solidarity, not only between all living beings, but including also those future beings who are as yet unborn; but for whose existence the living man of to-day is preparing through his care of his own strength and his own virtue. To have intentionally begotten a son better than himself will be a proud victory for the man who has attained the higher sexual morality; and such pride will be no less keen than that of the artist, who by perfecting his marvelous talents has created a masterpiece.

The statistics collected by Quétélet demonstrate that "too precocious marriages either occasion sterility or produce children that have a smaller probability of living."

They prove furthermore that the number of children who die is largest in marriages contracted at the age of sixteen or earlier, and becomes lowest among the children born of marriages contracted between the years of 29 and 32. During these years also the parents are most fertile: as is shown by the following tables:

SANDLER'S FIGURES BASED ON THE FAMILIES OF ENGLISH PEERS

Age of parents at marriage Percentage of deaths of children before attaining marriageable age Average births to each marriage Percentage of births to each death 15 years 35 4.40 0.283 16-19 years 20 4.63 0.208 20-23 years 19 5.21 0.188 24-27 years 12 5.43 1.171 Age at the time of child's birth Percentage of deaths to each birth Average number of births in one year of marriage 16 years 0.44 0.46 17-20 years 0.43 0.50 21-24 years 0.42 0.52 25-28 years 0.41 0.55 29-32 years 0.40 0.59

The results of a recent research show that famous men have hardly ever been the first-born, and that the great majority were begotten of parents who were at the time between the ages of 25 and 36 years.

Variations of Stature with Age, According to the Sexes.—The general laws of the growth and involution of stature are pretty nearly the same for the two sexes. The female stature, beginning at birth, averages throughout life somewhat less than the male.

But since the development of puberty takes place earlier in woman than in man, the female child manifests the characteristic increase in stature at an earlier age than the male; consequently at that age (about eleven) she overtakes him, and for the time being both boy and girl are equal in stature. But as soon as the boy enters upon the period of puberty, he rapidly surpasses the girl, and his stature henceforth steadily maintains a superiority of about ten centimetres (nearly four inches), as is shown by the deviations between the two parabolic curves, representing the variations of stature in the two sexes. Even the involution of stature occurs precociously in women, as compared with man.

Variations in Stature due to Mechanical Causes of Adaptation to Environment

Variations due to Mechanical Causes. Transitory and Permanent Variations. Deformations.—The individual stature is not a fixed quantity at all hours of the day; but it varies by several millimetres under the influence of mechanical causes connected with the habits of daily life. In the morning we are slightly taller than at night (by a fraction of a centimetre): in consequence of remaining on foot a good deal of the time during the day, our stature is gradually lowered. This is contrary to the popular belief that "while we stand up our stature grows."

As a matter of fact, in the erect position the soft tissues that form part of the total stature are under constant pressure; but being elastic, they resume their previous proportions after prolonged rest in a horizontal position.

Consequently at night, especially if we have taken a long walk, or danced, we are shorter than in the morning after a long sleep; the act of stretching the limbs in the morning completes the work of restoring the articular cartilages to their proper limits of elasticity. Nevertheless, according to the mechanical theory accepted by Manouvrier, persons who are habituated from childhood to stand on foot much of the time (labourers) interfere with the free growth of the long bones in the direction of length and at the same time augment the growth in thickness; hence the skeleton is rendered definitely shorter in its segments as well as in its bones (i.e., a shallower pelvis, shorter limbs, etc.). The result is a stocky type with robust muscles: the europlastic type, which is found among labourers. On the contrary, a person who spends much time reclining on sofas among cushions, and taking abundant nutriment, is likely to tend toward the opposite extreme; bones long and slender, the skeleton tall in all its segments, the muscular system delicate; this is the macroplastic or aristocratic type. According to Manouvrier, when a person has a long, slow convalescence after a protracted infectious malady such as typhoid, recumbent much of the time and subjected to a highly nutritive diet, it may happen, especially if he has reached the period of puberty at which a rapid osteogenesis naturally takes place in the cartilages of the long bones, that he will not only become notably taller, but will even acquire the macroplastic type.

The macroplastic type is artistically more beautiful, but the europlastic type is physiologically more useful.

It is not only the erect position that tends to reduce the stature, but the sitting posture as well. In fact, whether the pelvis is supported by the lower limbs or by a chair, the intervertebral disks are in either case compressed by the weight of the bust as a whole. If, for example, children are obliged, during the period of growth, to remain long at a time in a sitting posture, the limbs may freely lengthen, while the bust is impeded in its free growth, and the result may be an artificial tendency toward macroscelia. This is why children are more inclined than adults to throw themselves upon the ground, to lie down, to cut capers, in other words to restore the elasticity of their joints, and overcome the compression of bones and cartilages. Accordingly, such variations of stature recur habitually and are transitory, and since they are associated with the customary attitudes of daily life, they are physiological.

But if special causes should aggravate such physiological conditions, and should recur so often as not to permit the cartilages to return completely to their original condition, in such a case permanent variations of stature might result, and even morphological deviations of the skeleton. For example, a porter who habitually carries heavy weights on his head, may definitely lower his stature; and in the case of a young boy, the interference with the growth of the long bones through compression exerted from above downward, may produce an actual arrest of development of the limbs and spinal column, presenting all the symptoms of rickets. Witness certain consequences of "child-labour" chief among which must be mentioned the deformities of the carusi [victims of child-labour, who from an early age toil up the succession of ladders, bearing heavy burdens of sulphur from the mines below.[18]] in the Sicilian sulphur mines.[19] As a general rule, all cramped positions that are a necessary condition of labour, if they surpass the limits of resistance and elasticity of the human frame, and especially if they operate during periods of life when the skeleton is in process of formation, result in deformities, and when the skeleton is deformed, the internal organs and hence the general functional powers of the whole organism, suffer even greater alteration.
