How does man defines his rationality? How does man act? And how he deals with the environment he belongs?
Man has his perfection and his imperfections. He is perfect in the order of being, but is insufficient in the order of operation. Which means that he possesses existence which makes him a complete being. He has a matter and form (body and soul) which makes him complete as a man. In that sense, he is perfect as a being.
But man is insufficient in the order of operation, both in his spiritual nature and his material nature. He has in him the elements of the body and soul, by whatever terms they may be called: body and soul, mind and matter, body and spirit. The body, while being complete as a body, is limited in its capacities (operation), limited in its structure (size, weight, strength), and limited in its duration (mortality). The mind (intellect and will) on the other hand, reaches out to the infinite, universal, the highest level of aspirations. His capacity to know (intellect) and his capacity to desire (will) are both infinite. His quest for knowledge has no end, and his desire for things has no end either. But this capacity to know and to desire is only in a mode of sequentiality, not simultaneity. That is, man is capable of knowing everything and of desiring everything not all at the same time but one after the other. They constitute man’s imperfections and limitations.
In spite of these limitations, however, man surpasses all other material creations by virtue of his intellect and will or what may be summed up as his rationality. Man is a rational animal who, unlike all other animals, is capable of thinking and desiring, of understanding causality, and capable of perceiving his ends beyond the here and now. He knows how to play the game in diversity and to adapt what he is accustomed to. These are the reason that man keeps on finding his purpose and continue to discover what he has to discover beyond imagination. These created man as different from all other creatures.
