Bundled with the Fear Psychology thesis is a review paper entitled “A Century of Psychoanalysis”, which discusses an old psychology that has not yet expired. It introduced ideas that were radical and alarming at a time when sexual matters were not for public discussion, but what was probably more alarming was the concept of 'unconscious' motivation of behavior. This aspect of the theory tends to have been forgotten or ignored.
Very interesting approach to explain the bases of fear
I find this explanation very interesting for many reasons. First: because it places fear in human beings deep in the nature of human beings, which can be traced easily in history as seen in territorial wars followed by ideological wars and the current economical and technological rivalry on both national and individual levels.
Second: because this theory places fear at a genetic level for the benefit of survival. Which can also be easily proven by simple observation of non-thinking insects, which facing a threat tend to flee although they do not possess the ability to think or plan their actions. And of course the same goes for higher animals. Thus fear in this explanation has a neurological sense rather than a psychological feeling. And escape or flight is a natural or genetic reaction to that neurologically perceived threat. Only in humans and animals with highly developed neocortex, such a neurological impulse is expressed as a feeling as well as a reaction.
Third: because this theory does not exclude the Freudian assumption that all fear has roots in the sexual make up of the infant. In fact it reinforces the sexually rooted fear theory by placing sexuality as another goal for achieving survival of the genes. And thus links fear to sexuality as both serve one common goal which is the perpetual survival of the genes.
