All human beings have specific basic physiological needs; need to survive, protection, movement, and valorization, relationship with the environment and others, among others. The biological unconscious is in charge of keeping our vital needs covered. It does so by regulating the functioning of our essential functions, of all the organs of the body and our instinctive behavior.
When we live a conflict, the biological unconscious is put on alert and checks the battle to see if it affects some basic need. Any conflictive situation that affects a basic need, putting it in danger, will generate an emotional impact, which may or may not be addressed by the person depending on their internal resources and their state of consciousness.
If the conflict is not addressed, an unmet biological need is generated that endangers the well-being of the person. To overcome this conflictive situation, the biological unconscious will activate an adaptive survival program called “disease.”
Chance And The Need In Biology
It would be evident to primitive man that a chicken egg would always be transformed into a chicken and a frog into a frog, but if it were given to reflect, it would mysteriously call the regularity of the natural processes of heaven and earth. Copernicus, Kepler, and Newton analyzed the harmony of the spheres and were able to predict the movements. In the nineteenth century, Mendel-without knowing anything about chromosomes-established the laws of inheritance applicable to all cellular creatures, from algae to oak or man, and Darwin clarified the origin of the species. Darwinian evolutionism is still attacked by the vitalists or practitioners of some religious sects, but it is a theory as firmly established as the atomic, which few profane would dare to question.
The discussion between finalists and determinists, which we thought ended half a century ago, was revived long ago by recognizing the phenomenon of phylogenesis in evolution (the progressive passage of traits from one species to another) as the vitalists claimed that the creative process is unique and that, obviously, had a purpose as the species improved. They said that there was “a solicitation” of the future and that all manifestations of life were “commanded” by the end to which they tended. The adversaries, on the contrary, we believe that it is an impulse that comes from behind, that the mutations -product of chance- can survive or not allow a better adaptation or disappear with everything and the new species.
The existence of a force – or a supreme value – of an “elan” or entelechy that directs evolution cannot be admitted; the power comes from behind, the dynamism is an integral part of the whole phenomenon and therefore there are arrests, failures or setbacks. The universe has no intentions: nature is indifferent to living beings.
