Why evolution cannot produce a mind

by Lenny Esposito

I’ve previously posted an article declaring how the mind is a fundamentally different kind of thing than the brain. I wanted to follow up with a couple of possible objections to the mind/brain distinction that people offer today. The first objection is known as emergence and its proponents claim that the mind, while different from the brain, emerges as the brain grows in complexity. Thus the mind is distinct from the brain but it is the evolution of the brain, growing more and more complex, that eventually produced the first mind.

Emergent properties are familiar in both science and philosophy and they basically mean that the whole cannot be described solely by describing its parts. For example, we can talk about a snowflake by its chemical composition. A snowflake is comprised of nothing more than H2O in a solid state. However, describing the chemical bonds that create H2O does not describe a snowflake. The snowflake is something more specific than the chemical reactions of H2O, and thus a snowflake is an emergent property of H2O. Flocks of birds, molds, even societies are used as examples of emergence, where these things are different than the sum of the parts. 1

Materialists will then use this kind of description to say that the mind may be an emergent property of the brain. It exists because the brain’s chemistry and electrical pathways are arranged in a specifically complex fashion. Just as the molecules of water or the grouping of people to form a

city emerges as a new property that didn’t exist in that entity’s building blocks, so the mind emerges as a new property of the brain’s makeup. Thus, they claim, the mind is a real property but it comes from the physical structure and function of the brain. No soul is required.

The Problems with Emergence

The explanation sounds good, but there are several problems with the claim that the mind is emergent. First, in a complex system where new properties emerge, those new properties fall into the same domain as the system’s constituent parts. In other words, any physical emergent system will produce emergent properties that can be described physically. Water may have properties that hydrogen and oxygen lack such as the ability to crystallize into a snowflake. However, a snowflake is still describable by using the chemical language of solid/liquid/gaseous states and crystalline structures. The components are physical and the new property is also physical. Likewise, cities emerge from groups of people getting together and choosing to live a certain way. People are sociological and cities are described sociologically.

The mind however produces mental properties. As we’ve said, mental properties are non-physical. Therefore there is still a difference in kind in the property one is trying to account for. How does one account for non-physical properties from purely physical substances?
