Hi Andi, this relates to our initial discussion. The philosophical definition of “awareness” (mental properties) here cannot be collapsed into its empirical (physical) definition. We typically infer an association between observed indicators of awareness (eg self-report) and awareness itself. This might be appropriate in other fields (eg cognitive science), but not when analysing philosophy of mind.
Science measures physical properties, and constructs models which explain their behaviour. In the context of cognition, it hypothesises psychological constructs described by observables. One such empirical construct is observed (aka physical) consciousness/awareness, and is identified by one or more traits; arousal, specific brain activity, self-report etc. The information processing construct of awareness (central processing of stimuli) is certainly advantageous to the organism and would have evolved accordingly. More advanced central processing constructs like self-concept and theory of mind confer additional advantage to the organism and likewise would have evolved. An example of one such advantage of higher order cognition (including the belief in mental properties) is the value the organism places on its survival and others of its own species that share this trait.
Here is a thought experiment to demonstrate the distinction between mental and physical (neurological) properties. An advanced carbon or silicon based organism could independently evolve a construct of “self” that exhibits awareness (including a belief in mental properties), but there is no obvious reason to assume that it has actual philosophical “awareness” (mental properties). It would function identically. More precisely, the “self” (software program representing the central processing of the creature’s nervous system) would function as if it is aware, but if some low level science (typically taken to be physics) provides a complete description of the functioning of the universe then the existence of a subjective observer is irrelevant to its function.
In my previous comment I was purely discussing the prospect of an evolutionary advantage to mental properties (constituting the subjective observer’s awareness). The only philosophy of mind in which such advantage can be afforded is substance dualism. Again, there may be philosophical purposes for such awareness independent of its function/lack of on observed reality (cf the anthropic principle). Likewise, as above, there are certainly evolutionary advantages to having evolved the information processing resembling such awareness. But under the current scientific paradigm (with the materialist monism physicalism) there is no physical process existent that cannot be explained by the laws of physics acting on non-sentient particles. The technical term for this anomaly is “overdetermination” - any mental laws or processes we conceive of are overdetermined by physical law. Mental reality is thus redundant.
The mind-body problem (interactionism and the undefined mental substrate for substance dualism, the strong emergence problem for physicalism, the combination problem for panpsychism, etc) and our perception of the causal relevance of our volition (free will) are often taken together. Many suggest that the solution to these may have a common ground (contemporary examples include invocations of quantum indeterminism - eg “free volition”, interpretations of quantum mechanics - eg the Copenhagen interpretation/measurement problem, etc). Yet they may be entirely independent.
What reason does anyone have to do anything if not on logical grounds? And logic itself is deterministic. A failure to maintain consistency in a decision making process speaks more to a division of mind or the conflict of desires (eg short/long term evolutionary goals, the integration of one’s first or second order theory of mind, etc). More often than not it is a failure to anticipate stimuli knowing its influence on our reptilian brain and prepare accordingly. It may even be a failure to take action when necessary, triggering an irreconcilable contradiction or a subconscious detection of genuine cowardice. Granted compatibilism cannot damn the sinner/despot, but who was responsible for feeding their evil? How consistent was their complacency or tolerance? How good should they feel today, and what will they do tomorrow?
