Thus, however brilliant an idea was Wernicke's in constructing the allopsyche (or, as it were, social and environmental side of the mind) for the purpose of classification, our own analysis promised to show that for genetic purposes the allopsyche was much less valuable. These delusions having a social content pointed far more often inwards at the personality of the patient than outwards at the conditions of the world. And case after case, having apparently an almost pure display of environmental delusions, turned out to possess most obvious defects of intellect or of temperament which would forbid their owners to react properly to the most favourable of environments. Hence, we believe, it may be generally stated that the clinician is far less likely to get valuable points as to the social exteriors of his patients from the contents of their social delusions than he proved to be able to get when reasoning from somatic delusions to somatic interiors. Put briefly, the deluded patient is more apt to divine correctly the diseases of his body than his devilments by society. Our statistical analysis, therefore, set us drifting toward disorder of personality as the source of many delusions apparently derived ab extra and tended to swell the group of autopsychic cases at the expense of the allopsychic group, In the statistical analysis of a group of cases corresponding roughly with the so-called functional group of diseases, we find false beliefs about the some on a somewhat different plane from those about the patient's self and his worldly fortunes. We can even discern through the ruins of the paretic's reaction that his false beliefs concerning the body are often not so false after all, and that his damaged brain of itself is not so apt to return false ideas about his somatic interior as about his worldly importance and plight. There then seems to be more reality about somatic than about personal delusions: the contents of somatic delusions are rather more apt to correspond with demonstrable realities than the contents of personal delusions. Accordingly our analysis of delusional contents includes a hint also as to genesis. Taken naively, the facts suggest a somatic genesis for somatic delusions exactly in proportion as these delusions are not so much false beliefs as partially true ones. What genetic hint have we for the delusions concerning personality? One genetic hint was obtained from a correlation of delusions with lesions in general paresis,[2] in which disease perhaps the most profound and disastrous of all alterations of personality are found. Amidst the other alterations of personality found in paresis, autopsychic delusions are characteristic: indeed allopsychic delusions are conspicuously few in our series. And, as above, the somatic delusions, fewer in number, can be fairly easily correlated with somatic lesions, or else with lesions of the receptor apparatus (thalamus) of the brain.
