Apart altogether from the questions of mysticism and symbolism, with which Jung and his followers have tended to surround the whole matter, it is I think, abundantly clear that normal psychic development involves a gradual emergence from a condition of dependence on parental authority and care to one in which the individual is dependent to a greater or less extent upon his own efforts as regards his livelihood, and upon his own judgment as regards his conduct[29]. Failure in such development will result in a relatively feeble adult personality--one which still seeks the support of its parents (or their substitutes), when it should have learnt to stand alone. Such failures are, however, (as all psycho-analysts will admit) of very frequent occurrence. Normal development in this respect appears to be at least as difficult as in the case of the sexual tendencies we have already considered, and is liable, as in their case also, to arrests and retardations at various points and to regressions to earlier stages of development, whenever serious obstacles and difficulties are encountered. [Sidenote: Self-preservation] It would seem possible to distinguish two main aspects of this process of development, though in real life these two aspects are, it is almost needless to say, throughout intimately connected with one another. The first, and more primitive aspect, is that which is concerned with the actual manifestations of vital activity for the purpose of self-preservation and for bringing about the fulfilment of the individual's aims and desires. During babyhood the child is almost entirely dependent on his parents or other grown-up persons for the accomplishment of these objects: at best he can only indicate by cries or gestures the nature of his wants, in order that others may satisfy them. As he grows older however, he has to learn to fulfil an ever increasing number of these wants himself--to feed, to wash, to clothe himself and to satisfy his other bodily needs, to walk abroad without the protection and guidance of his elders, and generally to attain his desires by his own efforts rather than to wait for the attentions of others. To keep pace with the ever growing wants and desires of the individual, a continuous output of energy is required, and it will sometimes happen that the motive force immediately available (the strength of the conation) is not sufficient to overcome the obstacles which prevent the fulfilment of a want. When this is the case, the individual may react in a variety of ways. If the conation is a relatively weak one, he may abandon his attempts to attain the desired end, at least in its original form; or he may content himself with an imaginary fulfilment of his desire. If the conation is sufficiently strong, however, it may continue to manifest itself in different ways; if the first means of approach is unsuccessful, other means will be tried, until the end is eventually attained.
