Every difference between parent and child is somehow assumed to be rooted in and ascribable to the inherent perversities of the parental-filial relation. When scrutinized, these will often be found to be wholly unrelated thereto. Ever are parents and children ready to take it for granted that their clashing arises out of the relation between them when in truth, viewed dispassionately and from the vantage-ground of remoteness, parent and child are not pitted against each other at all. They are persons whose conflict has not the remotest bearing upon the relation that obtains between them. Would not much heartache be avoided, if parents and children clearly understood that the grounds of difference between themselves, however serious and far-reaching these sometimes become, are not related to or connected with the special relation that holds them together? Thus the irritations of propinquity may not be less irritating when seen to arise out of the fact of physical contact rather than from the circumstance of intellectual antagonism or moral repulsion, but it is well to know that such irritations are not the skirmishes of life-long domestic war. I say "irritations of propinquity," for, excepting among the angels, the status of propinquity cannot be permanently maintained without at least semi-occasional irritation. Professor R. B. Perry,[F] dealing with domestic superstitions, declares, in reference to scolding: "The family circle provides perpetual, inescapable, intimate and unseasonable human contacts.... Individuals of the same species are brought together in every permutation and combination of conflicting interests and incompatible moods.... The intimacy and close propinquity of the domestic drama exaggerates all its values, both positive and negative." Not only does the unavoidable persistence of physical contacts account, however unprofoundly, for occasional differences in the home, but another and parallel circumstance ought never to be lost sight of. There are two samenesses in the home, the sameness of blood and the sameness of contacts. Putting it differently, the oneness of environment for all the tenants of a home continues and sometimes intensifies the strain in either sense of blood-oneness. This may sound playful to those who have never bethought themselves touching the enormous difficulties that arise in the home insofar as some parents, having inflicted a certain heredity upon their offspring, are free to burden these filial victims with an environment escape from which might alone enable them to neutralize or palliate the evil of their heritage. I have in an earlier passage asked the query whether filial revolt is not the unconscious protest of children against the authors or transmitters of hereditary defect or taint.
