Thus the study of property interests in man emphasizes the fact that these are more than the resultant of a blind instinct to keep that which satisfies fundamental needs. With the operation of intelligence the various impulsive factors directed toward the acquisition of some property object are ordered, through permanent association, into a relatively stable sentiment. Sentiment is connected with sentiment just as one property value involves another. The development of self-consciousness is materially assisted by the integration of those sentiments about property values made permanent through their incorporation within the orbit of the self's activity. One may no longer conceive of property as we did among the lower animals simply in terms of the end-object satisfying basic need. The self has developed sentiments of possession and of ownership centred about primitive property values and the acquired values assimilated to these. Animistic identification of the self with this property strengthens to a further degree this personality-property sentiment relationship.
