The foundations of psychology were set upon the discovery of the relationship between biology and philosophy. The birth of psychology is a direct result of these two studies combining to make an intriguing study of human behaviors, emotions and reactions.
Psychology became equally important to other studies when it became apparent that it reflected both biological aspects as well as aspects of philosophy. Combined, these two studies allowed the discovery that people exhibit behaviors and emotions for many reasons. Human’s exhibit behaviors(s) in reaction to environmental factors, taught behavior, natural instinct, as well as an array of other scenarios trigger such behaviors. “Humans are complex creatures whose psychological experience lies at the intersection of biology and culture”(Kowalski &
Westen, 2005).

Psychology was (in some perspectives) stumbled upon in very early biological studies. It was observed that patients with head trauma injuries were test subjects to the identification of

the correlation between the human brain and physical responses. This discovery opened the door to the study of human psychology. The finding that the human brain interacted with the body in producing reactions and actions led to an entirely new world of study filled with fascinating aspects, now known as psychology. The foundation of psychology is built largely upon philosophy and was rooted from such philosophers such as Aristotle and Descartes.
Psychology has been traced back as far as the seventeenth century, but did not evolve into a separate discipline until the 1800’s. Rene Descartes was the first to introduce dualism. Dualism is the assertion that the mind and body are two separate entities that interact together to form the human experience. The debates of yesterday are still often contemplated. For example
