It is principally because a displacement of this sort can be much more easily produced in certain kinds of neurosis than in others, that neuroses differ from one another markedly in their amenability to treatment; what Freud has called the Transference Neuroses[146] (such as Hysteria or Obsessional Neurosis), in which the patient, though unable to adjust his emotions to the level required for satisfactory adult life, has nevertheless for the most part attained--and retained--the stage of object-love, comparing very favourably in this respect with the Narcissistic Neuroses (such as Paranoia), in which the patient has regressed beyond the stage of object-love to the relatively infantile level at which his emotional outlets are sought only in, or in connection with, his own person. [Sidenote: The displacement of parent-regarding feelings, on to objects other than individuals] All the displacements with which we have been hitherto concerned have at least this one important feature in common, that the feelings and tendencies originally directed to the parents are transferred to definite individuals. There are, however, certain forms of displacement, of very considerable sociological importance, in which this is no longer the case, the parent substitutes being found, not in any individual persons, but in groups, places, societies and institutions. [Sidenote: Home] Thus in many cases the home, as the place in which the parents lived and in which the feelings of love, tenderness and admiration towards the parents were first developed, acquires and retains throughout life a peculiar attractiveness, in which piety, tenderness and pride are intermingled and which is, it would seem, to a very large extent derived from the emotional attitude of the child towards the parents themselves. The attachment to the home in this sense frequently manifests itself in home-sickness whenever the individual is compelled to leave his native place or native land; those who suffer from home-sickness to an unusual degree or for an unusual length of time being in most cases burdened with an overstrong attachment to and dependence on their family, or certain members of it, having failed to free themselves adequately from their infantile fixations in this direction.
