“ Human being’s possess the cognitive ability to survey and study the biological and cultural constraints that influence us in order to gain an enhanced understanding of who each of us are. Comprehension of what comprises a self allows human beings to monitor and regulate their thoughts and actions and therefore revise and modify their sense of self. How much conscious control we assert over our minds as well as what decisions through default we leave essentially unregulated and in the sole providence of the unconscious mind determines our self-identity. Self-identity in turns affects personal decision-making, which alters our external world. The combined impact of millions of people making conscious choices exerts a profound impact upon reality, the physical world that is constantly in flux. ”
