[The primordial genesis of psyche: emergence and formalization]

Although there is no doubt that life was preceded by a purely physical universe from which it emerged, still there are some conceptual blanks which are necessary to analyse in order to make intelligible not only the evolutional origin of sensibility, perception and conscience but also its settlement in the process of evolution and the contribution of psychicsm to the efficiency of organisms as tele-onomical systems. Nowadays science considers that this happens because of a continuous emergence of novelty in organisms with a more and more developed and complex nervous system, which facilitates actions of adaptation seeking optimal survival. According to Zubiri, the basque thinker who we intend to analyse here, the humanization springs up from potentiality of matter, through a process of transformation, systematization and elevation. Intelligence emerges as a result of biological hyper-formalization so that man can survive taking over reality. If this function is increased, it will give richness to psychic life and, as this is a changeable activity, it can admit enlargements, retractions and internal modifications.
