No, it doesn’t. (Reductive) Materialism (aka Physicalism) is still anything but an empty doctrine. It holds that…
- There is nothing more to reality than the concrete matter-energy-space-time system (MEST).
- All elements or fundamental entities of MEST are lifeless and mindless (nonvital and nonmental) concrete entities belonging to the ontology of physics.
- All chemical, biological, psychological and sociological entities are fundamentally composed of or constituted by nothing but such concrete entities.
“The materialist, holding that the world is matter, is not wedded to any one doctrine of the nature of matter.”
(Williams, Donald Cary. “Naturalism and the Nature of Things.” In Principles of Empirical Realism: Philosophical Essays, 212-238. Springfield, IL: Charles C Thomas, 1966. p. 220)
“As soon as physical realism is set forth with some degree of precision and polish, the same detractors who once charged it with being an odious grotesquerie are ready to charge it with being an obvious truism, having no intelligible alternative. On the contrary, the statement of materialism thus clarified not only means something; it means something distinctive, arresting, illuminating, a thesis so far from empty and obvious that, unfortunately, it has been expressly denied by a great majority of philosophers and philosophasters. It has seldom been wholly without adherents; it is the philosophy taken for granted by a good many educated men, including especially those engineers and scientists who have not been corrupted by mysticism or phenomenalism; but most of the populace of Christendom, and most metaphysicians dignified with livings, lay or ecclesiastical, have emphatically refused to admit that everything in the universe can be ruined or repaired by local rearrangement. They have believed in enormous amounts of nonphysical, nonspatial, and even nontemporal reality, beyond the corruption of moth and rust, either supplementing material reality or supplanting it: minds, soul, spirits, and ideas, transcendent ideals and eternal objects, numbers, principles, angels, and Pure Being.”

"[T]he intuition behind physicalism, or materialism, seems quite clear, and does not seem to depend on any sophisticated account, let alone definition, of what it is to be physical. When it comes to it, physicalism is just the view that life, mind and society have arisen in a lifeless, mindless and nonsocial world, depend for their reality on the basic laws of that world (which are not recognizably biological, psychological or social) and in fact are merely special ways in which the stuff of that world behaves.
What this suggests is that by default we can call the lifeless, mindless and nonsocial the physical, or better: merely physical. The idea is that physicalism relies on a commonsense conception of ‘dead matter’. This is a tacitly negative understanding of ‘physical’: not very much metaphysically interesting, and certainly too poor to count as a definition of ‘physical’. On the other hand, insofar as we can come by an account of what is characteristic to the living, the mental and the social—not an easy affair, it seems, but more tractable than defining ‘physical’ from scratch—, it will not be completely uninformative either.
More importantly, it seems precisely good enough to articulate the core idea of physicalism. We can imagine several parties, each with their own understanding of ‘physical’, but all in agreement on one point: life, mind and society do not require an irreducibly or sui generis ‘vital’, ‘psychic’ or ‘societal’ addition to the ‘physical’, whatever that is supposed to be. Also, a physical domain that is demarcated negatively can easily be seen to comprise, apart from properties like charge or spin, properties like weight, length, shape, transparency, treacliness, etc.; as well as chemical properties like being a catalyst or being a corrosive substance. This, it seems, articulates fairly precisely the notion of ‘physical’ as we find it in the discussions on the metaphysics of mind."
