If something at the moment of death contains the same matter as that something when alive, what is lost?

How does physicalism (physical monism) explain what that loss is?

The state of being alive is lost (that is, it ends) when something dies. The state of being alive is mostly defined by having the ability to deliver the right chemistry to the right places in the organism (for humans, the brain) at the right time at the right temperature.

Since there are many more ways for the chemical systems in your brain matter to be incompatible with life than there are for it to be living, and since the brain's living state takes a continuous supply of chemical potential energy to maintain against equilibrium, the state change is usually irreversible unless the body's self-ordering processes can be promptly restarted or duplicated with high quality CPR. Cooling the brain to slow the rate at which brain chemistry seeks equilibria incompatible with life lengthens the window of opportunity.

Monism doesn't really come into it. I've never heard of anybody getting a Do-Not-Resuscitate order or refusing deep hypothermia during cardiac surgery because they believe their soul is the boss of their chemistry.

  • "[...] being alive is [...] having the ability to deliver the right chemistry to the right places at the right time at the right temperature": Nowhere in all scientific knowledge life is defined as such. – RodolfoAP Jan 09 '24 at 06:55

  • Homeostasis means stability by self regulation, no relationship with "right time", "right temperature", "right chemistry", "right places in the organism [which in humans is] the brain", etc. In any case, it changes your answer, you should use the term on it; 2) Nowhere in scientific knowledge life is defined as homeostasis; 3) An encyclopedia is not scientific knowledge.

  • Unfortunately the last paragraph reads like a complete non-sequitur. Monism (generally speaking and in this context) is about what types of things do or do not exist, such as the soul in addition to matter. But the last paragraph seems to imply that if the soul is not capable of overriding physical circumstances of the body, it doesn't exist (and therefore couldn't be lost) (which would be a confusion of necessary vs. sufficient). Maybe I'm just not getting the connection you're trying to make. – LarsH Jan 09 '24 at 15:41

    @LarsH I intend no such implication. My point is, substance dualists do not believe that the soul regulates their chemistry, so the fact that life is sustained by chemistry and ends when the system's ability to chemically self-regulate fails is irrelevant to the truth or falsity of substance dualism. – g s Jan 09 '24 at 16:05

    @larsH For an analogy with something that isn't alive or chemically active - suppose I have a big indoor freezer whose walls are made of ice, not insulated metal. Even the compressor and the coils, although made of metal, are so flimsy that they would collapse under their own weight except that they are supported by rigid structures made of ice. The freezer is capable of freezing things while its self-regulating process - pumping heat from inside to outside using its compressor and refrigeration coils - is sustained by electric power and the proper function of all of its mechanical parts. – g s Jan 09 '24 at 16:55

    If power is removed, the freezer stops working and the ice begins to melt. If power is promptly restored or if the heat pump is driven by some other power supply until power can be restored, the freezer can be saved, but if it is left alone for long, the whole thing will be irreparably reduced to a pile of crushed compressor parts in a big puddle of slush, whether there was a person inside the freezer participating in the function of the compressor or not. – g s Jan 09 '24 at 16:56
