Why Does It Feel Like Something? An Evolutionary Path to Subjectivity
How does the brain generate subjective experience – the feeling of 'what-it's-like' to be us? Explanations differ: some seek physical mechanisms (Physicalists included), while others find such accounts lacking or impossible in principle. This article presents a specific physicalist and functionalist hypothesis: subjective experience arises from the brain's evolved capacity...
These are great points! Saying the feeling is the function is the big leap/hypothesis here, not something the mechanics proves directly. The exact 'why this feeling for that function' map isn't figured out yet – Section 9 flags that as ongoing research. It's called 'mechanical' because the underlying process described (the predictive modeling stuff) is physical/computational.
I added a note to conclusion to make it clearer the goal here is different from something like dual-aspect monism (which might posit two basic aspects). This article is trying to see if the feeling can be explained from the mechanism itself, even if that explanation isn't complete.
