We will have the opportunity to present at the time the positivist theory of knowledge. For now, in conclusion, it remains only to notice the relationship between knowledge, skills and arts. The primitive tools-ax, hammer, chisel, drill, saw, plow, etc .- are an extension of the hand, this "helpful to the appropriate" (Aristotle), and in principle operate solely on a practice field immediately. With respect to art, it would seem that only displays the sake of fantasy and beauty, and its connection with objective knowledge is as nonexistent as in the case of tools. Nothing can be assumed wrong.

Pottery and sculptural techniques without the idea of a god as Yahweh, who "molded" man of the dust or mud, is unthinkable. Without a cave painting schematically representing hunters, dams and the graphics ceremonial written language and logic are conceivable relational primitive. Without the projection of an organ as the hand that are the tools of carpentry, farming, metallurgy, etc.., It is possible agency concept and function, and even the idea of a passive matter. Man is made so that only understands its own being from a construction figuration and the surrounding world. His awareness of itself is gaining accuracy and content through such knowledge that midwives are the arts and techniques.

This process is illustrated in an exemplary way by the recent achievements in cybernetics and information theory, whose immediate result was not only more subtle build machines, but to suggest new perspectives for understanding animal and human behavior.

In ancient mythology the man is beginning to accept and build that specific destination. Not be known for breaking the illusion of direct contact with her will end. At the same time cut the illusion of desire, wonder about the truth means breaking from within the complex web of commandments and rituals built up during the long period before the technical, visual arts and poetry. With echoes tragic and epic, the great myths gloss aspects of this gradual break with the magical spirit, which is the agricultural revolution of the Neolithic and urban.

As the ritual is a broad tendency of the living (and, as such, inevitable), will in fact only one substitution, but of incalculable consequences. While the desire governs the merger with nature, the ritual is essentially magical ceremony of sacrifice to gods and demons worship unique. Then emerge the big speculative operation of monotheism. Beyond this, a culture, the Greek people as a new rite assumes global free examination of the reasons, and as a myth the abandonment of the cave where a routine chained to perceive only shadows of cosas¹.

The man before the Greeks believed that their duty is an uncompromising defense of the traditions. The Greek thought to the truth defends itself, that error alone needs support, and must succumb sooner or later-sooner rather than later, "everything that does not resist the fair trial of the understanding. Science was born.
