We recognize consciousness by its effects because we can only recognize anything by its effects.
Inasmuch as we recognize consciousness, we recognise it by its effects because we can only recognize anything by its effects. But we have no way of confirming how our accurate our guesswork is, particularly regarding aspects of consciousness that aren’t behavioural or functional , ie. the hard problem aspects.
The causal explanation for talk about consciousness has to either exist entirely within physics (in which case anything we say about consciousness is causally unrelated to consciousness, which is absurd), or there needs to be some place where the laws of physics are violated as the immaterial soul is observed to be “tugging” on the brain (which is in-principle experimentally detectable).
Or the laws of of physics are an adequate description of reality, not the only one.
