Yes, my definition would be more
originalist ("because it has been this way") if you may.
Consciousness has been a definition of the inner human experience made by humans themselves, regardless of the lack of clear understanding of what precisely denotes consciousness. Can animals experience what we experience? Well, maybe, but that's not consciousness, as I'm reserving that term to define the human inner experience exclusively. In particular, I'm here to argue that a "scale" proposed by parent is not possible. Why? Because the concept itself was born exclusively from the human experience to summarize the undefinable complexities and interactions of the human mind. Given consciousness is undefinable by specific terms and their relationships (ie. there's no "formula"), we can't really assign partial consciousness consistently to other species. We can say "bees play" or "dogs fear" but that can't really be put in a consciousness scale, because what would "10% conscious" even mean?
> it could be just as possible that animals experience consciousness in the exact way we do
Other species may experience something analogous to consciousness as they also experience complex interactions of different traits in their minds. But it's always going to be their own interaction and I would not call it consciousness. And whatever it is it's definitely not the exact way we do.
