This full frank manifestation of feeling holds good more especially of those states of bodily comfort and discomfort which make up the first rude experiences of life. It is necessary for the child’s preservation that he should be able to announce by clear signals the oncoming of his cravings and of his sufferings, and we all know how well nature has provided for this necessity. Hence the fulness with which infant psychology has dealt with this first chapter of the life of feeling. Preyer, for example, gives a full and almost exhaustive epitome of the various shades of infantile pleasure and pain which grow out of this life of sense and appetite, and has carefully described their physiological accompaniments and their signatures.[126] ----- Footnote 126: _Op. cit._, Cap. 6 and 13. ----- When we pass from these elementary forms of pleasure and pain to the rudiments of emotion proper, as the miseries of fear, the sorrows and joys of the affections, we have still, no doubt, to do with a mode of manifestation which, on the whole, is direct and unreserved to a gratifying extent. A child of three is delightfully incapable of the skilful repressions, and the yet more skilful simulations of emotion which are easy to the adult.[127] Yet frank and transparent as is the first instinctive utterance of feeling, it is apt to get checked at an early date, giving place to a certain reserve. So that, as we know from published reminiscences of childhood, a child of six will have learnt to hide some of his deepest feelings from unsympathetic eyes. ----- Footnote 127: This does not apply to older children. As Tolstoi’s book, _Childhood, Boyhood and Youth_, tells us, a boy of twelve may be much given to straining after feelings which he thinks he ought to experience. ----- This shyness of the young heart, face to face with old and strange ways of feeling, exposed to ridicule if not to something worse, makes the problem of registering the pulsations of its emotions more difficult than it at first seems. As a matter of fact we are still far from knowing the precise range and depth of children’s feelings. This is seen plainly enough in the quite opposite views which are entertained of childish sensibility, some describing it as restricted and obtuse, others as morbidly excessive. Such diversity of view may no doubt arise from differences in the fields of observation, since, as we know, children differ hardly less than adults perhaps in breadth and fineness of emotional susceptibility. Yet I think that this contrariety of view points further to the conclusion that we are still far from sounding with finely measuring scientific apparatus the currents of childish emotion.
