ABSTRACT
Man's behavior and mode of experience is different even though no new inner system appeared in its embryology, such as gastrulation for the invertebrates and neurulation for the vertebrates. Man starts his career as a cell, the ovum, which utilizes molecules and atoms of its physical system as signs. Language presented us with the key for unveiling the meaningful nature of evolution in its fullness. Man makes the system that constitutes man. The ascent in evolution is the result of the appearance of new inner systems as representatives of new individualized options in the global process of communication, among them the noetic system. The noetic system is an interpersonal system not only as a result of its origin in the mother-child relationship of the neural communication, but even more as a consequence of identical acts in all the egos.
