I expect that consciousness is a human nominative concept. Like religion, it will become smaller as science encroaches. In 1994, David Chalmers presented his idea of the hard problem of consciousness in a lecture, Toward a Scientific Basis of Consciousness, but I feel this is more due to the insufficiency of language than anything else. To me, consciousness isn’t well defined. It’s like a medical syndrome. It’s just a grouping of seemingly related conditions that haven’t yet been parsed. In time, it may be determined that they weren’t even related in the first place. Apophenia and cognitive dissonance are two significant human biases that affect perception.
At core, consciousness might be functionally reduced to that of an interpreter. Some have posited that the only thing that exists is ‘information’, whatever that means, so there only needs to be an interpreter—a translater. If that interpreter is defined as consciousness, then so be it. This appears to lead us to a Cartesian place—though it doesn’t follow that the self or ego exists. This would be a second-order event.
Anyway, just rambling. As seems to be the case lately, I’ve got little time to develop my thoughts. At least I’ve captured them for now.
