If my mental processes are determined wholly by the motions of atoms in my brain, I have no reason to suppose that my beliefs are true…and hence I have no reason for supposing my brain to be composed of atoms.”– C.S. Lewis
One of the issues with an evolutionary perspective is the idea of materialism. First off, let’s define materialism in these terms. Materialism is the idea that everything can be traced back to physical matter; there is no spiritual aspect to things or even a mind apart from a physical brain. Everything can be explained as a chemical interaction. But how can this be logical?
The largest issue with this point of view that often comes to my mind is the conscience found in every person- the moral compass inside of us all that separates right from wrong and produces feelings of guilt. How are human beings born with an idea of what is good and what is bad? Materialism would say that it is all matter, there is no true good or bad because everything is simply chemicals reacting to create a response. Does materialism explain this idea of a conscience in humans? I believe it does not.
Another major issue with the idea that all things are only physical is the idea of truth itself. If every thought is simply chemicals interacting, then how can we trust anything that we say, or others say? The materialist point of view says that you have no control over what you say, think, and do, because it is all simply a physical interaction within your brain that does not involve immaterial feelings or knowledge. Once again, how can we believe in ourselves and those around us to make “good” choices when they actually have no control over their thoughts or actions.
How do beliefs and values play a role in a materialistic evolutionary perspective on the world? They simply don’t make any sense. The thought that unguided evolution would produce beings that hold believes, pursue truth, and have values does not directly align with evolution, nor materialism. Evolution simply cares about behaviors, not beliefs. Materialists have no substantial argument as to how the ability of humans to think and hold personal views on things developed from only physical matter.
This leads us to the incredible complexity of the world and all processes that occur within. As science has progressed and academia has been able to study life on a much more microscopic level, the simple theories of evolution have begun to fall apart. The chances that a random occurrence would cause such complex and incredibly-designed life forms is just not plausible or rational. In this case, there had to be something (or someone) immaterial, that is supernatural, that created and designed such processes. This view completely clashes with the views of a materialist who would believe that random events caused unguided evolution, which produced human beings.
When talking to someone who you know as an evolutionist, bring up the idea of materialism. Ask them if they truly believe that every thought they have and every belief they hold is simply a chemical reaction occurring in their brain. Bring up the fact that if materialism were true, how could we know anything to be trustworthy or moral. Also, ask your friend about their conscience and if they feel guilt when they do wrong, then ask them to explain how this developed simply through matter. Always be polite and respectful, showing the love of Jesus in every response and interaction.
If you want to educate yourself further on the idea of materialism, I highly suggest researching and reading articles on Thomas Nagel. Nagel is an atheist, but is not afraid to say controversial things on reason and evolution itself.
