Abstract
The nervous system comprising a great number of cells, that connect with each other by means of their extensions, is the single organ that passes from cellular redundance to a huge combinative redundance. The combinative redundance offers it the freedom to lead the information through very many paths. In order to lead the information through the paths with which they establish the most adequate correspondence between the state of medium factors and the state of the elements of the organism, the neuronal network is in a continuous state of being structured and restructured. By the modification of the threshold and by means of the synapses, different logical circuits appear, by means of which the nervous system recognizes, selects, estimates and leads the information through the most adequate paths. In order to be able to contribute to the adaptation of such a complex system-as the organism-in a very variable state, the neuronal network must estimate the information not only from the point of view of veridicality, concerning its truth or falsity, but also from the point of view of utility, necessity, pleasure, or displeasure, that the events generating the respective information would have for that organism and even for other organisms processing the information from the point of view of their ethical and esthetic values too. In order to contribute to the selfplastic and alloplastic adaptation of the human organism, the resulting decision will have to intersect the sets of all these values.
