The Interactions Between Instinct and Intellect and its Impact on Human Behavior Length: 324 Pages The oldest musical instrument found is a flute made of bone that is estimated to be over 50,000 years old. Aristotle wrote the first book on arts, poetics. Since then it has been debated what art is at the highest levels. However, the world of philosophy admits that we still have not been able to articulate a definition for this seemingly simple word of art that would be acceptable to all. This shows that we do not understand it well enough to properly define it. This confusion stems from an inadequate philosophical understanding of it and, thus, we have been relishing that, which we do not comprehend. One of the reasons for this lasting confusion stems from the fact that we try to understand arts by studying art objects in the physical world. However, without being able to identify what in the mind longs for art in its metaphysical realm and why, we will never grasp it. This is why we have been mixing novel, painting, music, acting, perfume, architecture, Persian rugs and poetry and so on and try to devise a definition to define them all. Although they all are art, they have nothing in common. This shows but a small fraction of our profound misconception of the world of art. Based on what mental force longs for which group of arts coupled with the structure of the art forms, they divide into three distinct and logical categories of 1- Rhythmic Arts, 2- Imitative Arts, and 3- Abstract Arts. Each of these categories connects with a particular mental faculty. Then, through this understanding we also get to see that there exists an inequity in the sensitivity and excitability of these corresponding mental faculties and we experience different intensities of pleasure from different arts. For example, some arts, like live music performed even by average artists will invoke emotions in many who may scream, cry and even faint at concerts, but they never react that way by observing the works of true masters of arts such as Michelangelo, Picasso or others in museums. This results form the imparity in the sensitivities of the corresponding mental faculties mentioned above. This view carries us deep into arts as a phenomenon and helps artists to further refine their arts and the art lovers to appreciate it even more. In the realm of sports, we learn that all sports have three things in common, aiming, speed and power or endurance. Yet these are the skills required for successful hunting. Hunting and warring is one of the male instincts as they acted these responsibilities through out the human evolution. Because instincts do not disappear in time, they have survived and find expression in different sports, and thus aiming, speed and power find their way into all sports. Females not being pressed by this instinct did not hunt or fight wars. It is for these organic reasons that males so readily become sport fanatics at the dismay of the women in their lives.
