With the human being’s born also comes the evolutionary need of relation and community among them in order to survive. All their lives are automatically related to the environment in which they were born, believing themselves absolute masters of their destiny. 

We know that only through the physical senses and mind can be known the world. As in the theory of Kant, the world is correlative of human knower, and, therefore, has the fundamental structure of our way of knowing.
