I don't see how talking about consciousness is necessarily a limitation to it being a by-product of physical processes. It could be that consciousness is simply an emergent property (a by-product) of the communication of billions of neurons that are connected in trillions of ways. Where neurons are emergent of chemical phenomena which are emergent of atomic phenomena and so on. I'm probably greatly simplifying the de…
I do agree, but to be fair, Epiphenomenalism makes a slightly stronger point. Not only is consciousness entirely a physical process, but the 'events' of consciousness (any thought, feeling, emotion, sensation you've ever experienced) has absolutely no impact on behavior. There is no feedback loop here. So, instead of Touch hot flame -> Feel sensation of pain -> Move hand It's... Touch hot flame -> brain processes eve…
All of this is at least intuitively easy to explain with added language and complexity in the brain. So like the chain would become:
Touch hot flame -> brain processes event (and then does complicated language processing, and complicated memory and emotion processing) and THEN sends signals to move hand or not move hand -> You experience all of this but it had no relevancy to the chain of events.
Where I would ponder the relevancy of consciousness is when it comes to attention and remembering things. Just from personal experience, I can read a book, watch a movie or listen to music and I will not remember a thing if I wasn't aware of it. Is awareness and consciousness the same thing? I don't know, but at least we are conscious of everything we are aware of, by definition, and not necessarily vice versa.
