Going to bat for "hard materialism"
In discussions like this the "materialist" is usually not present, and has to be represented by a straw man. Because materialism is playing the role of a dumb punching bag instead of a serious hypothesis, no serious alternative paradigm is present either. "No true materialism" and cheap dismissal are common. At no point does anyone get a clear idea of what we are actually supposed to believe, only that materialism is for dumb-dumbs.
So I'll go to bat for the "hard materialist" worldview and challenge you all to come at it with something other than FUD.
Hard materialism says there is a simple and deterministic (up to randomness but not reverse-causality) layer of physical law underlying all phenomena. All complex high-level phenomena can be reduced to, explained, engineered, and even simulated (when computational feasible) in terms of the base layer reality, or are confusions that dissolve on inspection. This has been the basic trend in science for the past couple thousand years. Let's nuance this to dodge a few of the usual straw-men:
* This is a paradigm, not a-priori deduction or even a particular concrete hypothesis. The claim is that it is consistent with observation and correct in practice to assume that all phenomena have material reduction.
* This does not claim that the warm redness of the sunset doesn't exist, but that it is explainable in basic physical terms.
* This is not a theory of subjective practical phenomenology. We don't experience or understand the world in terms of basic physics. The claim is that all other concepts we use (can) have a particular kind of relation to basic physics, that of "reduction".
* Concepts are material patterns of connection and behavior which live in the mind, which is itself a pattern of behavior of (carefully arranged) matter reducible to physical action. They don't have any absolute existence separate from matter.
* Math etc is special concepts built on the observation that matter is predictable by "abstract" analogy, not just direct physical repeat.
* "Matter" is subject to various quantum field nuance. I'm using it informally to refer to whatever substances, fields, or other substrate we believe in today.
* Our subjective experience is real and physical, encoded in the action of whatever (physical) substrate encodes the mind. There are some paradoxes and gaps in how the mind reflects on itself, but these are akin to limits on provability or knowability, not a paradoxes for the theory.
* Free will refers to the fact that our decisions determine the future (ymmv) and are not pre-determined by any process other than the decision process itself. It is not related to physical determinism.
* This does not claim that "quantity" (eg of people) has any moral primacy over "quality" (eg a hungry tiger) or vice versa. Nor does it claim that "material" things like cars are more valuable than experiences or knowledge.
Despite the above, I want to be sympathetic to those with non-materialist worldviews. I just don't know what they actually mean at this level of detail. What is the actual alternative to this?
