Modern day atheists are prone to argue that human morality has developed as a result of the process called natural selection. It is claimed that our moral standards are simply genetic chemical compounds that are shaped according to evolutionary needs. In other words, the formation of human morality is supposedly prompted by the conditions of current physical surroundings, in the same sense that the physical components of the body adapt to environmental changes. The naturalistic worldview maintains that our morals have developed by mere chance. In short, evolutionists claim that continually changing behavioral patterns are what morality consists of. Adherents of this so-called new science called evolutionary psychology believe that everything regarding the human personality can be explained adequately by evolutionary forces.
It is illogical to the highest degree to equate morality with physical adaptations that evolve in response to environmental conditions. If our moral codes were determined individually by our chromosomal makeup, then how could we reward or condemn the actions of other people? If no distinction is made between mankind and the animal kingdom, then why should we be disgusted when people engage in acts of bestiality? Why not love our pets rather than friends and relatives? Why not act uncivilized as do wild animals? Why even wear clothing? If morality evolves, then that means things we deem moral today may be evil in the future and visa versa. These so-called evolutionary explanations are simply imaginary, subjective, hypothetical constructs. It is not coherent philosophy because it is not consonant with the reality of our nature. Evolutionary Theory cannot account for how or why we ought to be moral beings.
We know that moral laws are not concrete objects, but rather abstract realities that can only be grasped through mental perception. Moral laws are intangible entities. They are not chemical or biological. Moral laws are spiritual and intellectual propositions that are communicated from the mind of one individual to another. Moral laws have been internally inscribed into our hearts by God (whether a person has the mental capacity to understand them is a separate issue). They enable us to formulate rational distinctions between good and evil or different degrees between either category. Not only do human beings naturally feel obligated to obey these moral codes, but we also feel guilty when we choose to violate them. Lastly, it is important to note that exterior conduct in and of itself does not prescribe us with a pattern of sound morality to follow, but rather offers us a description of various moral patterns. The objective moral standard referred to here governs our behavior because it judges whether it is good or bad.
The evolutionary worldview, by definition, fails to give account for the existence of transcendent moral laws. We must not adhere to the "survival of the fittest" worldview, for it is utterly cruel and selfish. The inherent self-centered design of the Evolutionary Theory opens the door to much persecution and discrimination of the lower-class, minority groups of our society. Not only does evolution leave absolutely no room for objective reasons for protecting the vulnerable, but the notion of natural selection is also totally indifferent to the suffering, weak people of this world. Why should we do good to others? The fact that we are able to choose acting in a morally sound manner is beside the point. Society can still adopt the abhorrent lifestyles. If there are no objective moral standards existing for us to abide by, then why should we not choose to act evil? What is evil? Why should we really care what other people think? If we educate our children into believing that they are nothing but animals, then they will also behave in that fashion.
If, on the other hand, there exists objective moral laws that are transcendent to the laws of nature, then it logically follows from the premise of the argument that there must also be a supernatural Law Giver. It follows that we can differentiate between good and evil. It follows that we actually have purpose in this life. It follows that life has objective value and meaning. These things can only exist, if a supernatural Law Giver inscribed them into the innermost part of our being, the soul. Morality is the foundation for all building blocks in life. Evolution only seeks to explain it away. Truth establishes all principles which form the basis of morality, and only through God that we can have such things. If naturalists continue on chiseling the concept of personhood in accordance with their materialistic philosophy, then they will inevitably be rendering our unique characteristics to mere projections of the human mind. The deconstruction of reality is a very dangerous thing.
