After millennia of evolution, his thought processes were sharpened under the pressure of his environment and he learned to rely on the power of his brain to an ever-increasing degree. Increasing brainpower demonstrated the trend of evolution to increase complexity because increased complexity provides for a high degree of specialization and higher specialization provides for improved adaptability to changing environmental conditions. Whereas prehistoric human societies benefited from the belief in the supernatural, the opposite situation prevails in our modern world. Man s environmental conditions have changed diametrically because science has transformed nature from something to be feared in awe, to something that is subservient to him. Man no longer is afraid of nature.
Man dominates nature.
The adoption of a religious belief system within modern society restrains rational thought processes because religion is the essence of irrationality and is a poor substitute for factual, scientific knowledge. Religion, magic and superstition do not provide consistent results. Science and rationality, based on knowledge and logic, is infinitely more reliable in achieving desired results. Rationality is synonymous with the subsequent development of logic and science. As we enter the third millennium, the scientific approach to the affairs of human existence has superseded the obsolete, ineffective reliance on a god or gods.
