Darwin’s Mistake According to Psychologists

In 1871, Charles Darwin proposed that the difference between human and nonhuman minds was a matter of degree, not kind. A 2008 publication by Cambridge University Press calls that “Darwin’s mistake.”

Animals with very different brains, and sometimes no brain at all, can perform the essential functions needed to live and survive. God has created various animal orders with what they need to fulfill their roles in the system of life. This explains the different sizes and capabilities of brains among animals. However, the mind is something more than just the brain.

According to the team of psychologists who authored the report, only humans possess a mind capable of “the higher-order, systematic, relational capabilities of a physical symbol system.” In this peer-reviewed journal, they wrote, “We show that this symbolic-relational discontinuity pervades nearly every domain of cognition and runs much deeper than even the spectacular scaffolding provided by language or culture alone can explain.” In other words, a vast gulf exists between the human mind and the brain power of any animal.

Darwin’s mistake, according to this Cambridge University article, was suggesting that all differences between humans and nonhumans are a matter of degree, not of kind. This theory is disproved by the fact that only humans can develop abstract thinking and writing because humans alone can invent and use symbols in communication.

When God created humans in His image, He gave us a mind capable of great achievements. Unfortunately, that ability can also be used for great evil. He gave us a spiritual nature with a desire to know Him. Yet, our pride can lead us to reject God and serve only ourselves. We humans are the only creatures who can choose to fulfill God’s purpose for us or to rebel against His will. Darwin’s mistake was to think the difference between humans and nonhumans was merely a matter of degree. It is truly a difference of kind.
