This is the 3rd version of the argument I’ve posted. The central claim hasn’t changed, but further considerations have helped me clarify the reason for preferring a rational, mind-like foundation and what the limits of that preference are. I want to set out this revised argument in one place so we can focus on what it claims.
Part of my reason for starting this thread is to challenge the materialistic view that I often see taken for granted in these discussions. A nonmental foundation has explanatory questions to answer. I want to examine whether a rational, mind-like foundation is a better explanation of conscious experience, understanding, and reasoning.
By “fundamental” I mean what’s basic to reality, viz., what things ultimately depend on and which doesn’t itself depend on something even more fundamental. The question is whether conscious understanding belongs to this basic nature or arises from something that’s completely nonmental.
Taking the rational and mind-like as fundamental or bedrock is my proposed account of the basis of the world and our individual conscious experiences. It doesn’t give us all the details, but an account can explain something without explaining every detail.
The argument is an inference to the best explanation. I’m not claiming that a nonmental account is impossible or that the conclusion follows with absolute certainty.
P1. We have conscious experiences, understand things, and reason about them. These faculties are connected. In conscious reasoning, we understand what we’re considering and how it bears on a conclusion.
P2. Both accounts must explain how these faculties have their basis in what they take as fundamental.
P3. If what’s fundamental is completely nonmental, conscious experience, understanding, and reasoning must arise from something nonmental. Describing a physical arrangement doesn’t, by itself, explain why that arrangement involves these faculties.
P4. If what’s fundamental is rational and mind-like, these faculties have their basis in what reality already is. On this account, individual minds express something already basic to reality.
P5. Taking these connected faculties as basic gives the mind-like account an explanatory advantage. It doesn’t require conscious understanding to arise from something completely nonmental. Other things being equal, this gives us reason to prefer it.
Conclusion. Other things being equal, we have good reason to favor a rational, mind-like foundation over a completely nonmental one as the basis of conscious experience, understanding, and reasoning.
The main point is in P5. If something rational and mind-like is at bottom, conscious understanding has its roots in reality’s fundamental essence. If what’s at bottom is completely nonmental, these faculties have to arise from something that lacks them.
Maybe they can. I’m not saying they can’t. I’m saying that must be explained, and that taking mind as basic offers an advantage.
Both accounts bottom out somewhere. That alone isn’t an objection to either argument. The question is what each starting point helps to explain.
“Other things being equal” leaves open whether other considerations outweigh the advantage I’ve put forth. It doesn’t require that every question be answered before we can reasonably favor one account over another.
