Time’s Arrow, Temporal Coding and Phenomenal Vehicle Externalism
This paper asks whether our brains can make use of objective temporal order (e.g. Morse code) to realize our experiences. There is plenty of evidence that rate envelope and relative spike time coding are ubiquitous in neural coding. But a look into the foundations of thermodynamics suggests that temporal order constitutively depends on the universal distribution of entropy, and it is not plausible that our experiences constitutively depend on anything as radically extrinsic to us as the universal distribution of entropy. The upshot is a quadrilemma. Assuming that the realizers of our experience can make use of temporal order, we must choose between one of the following four poisons: 1) deflationism about phenomenal consciousness — roughly, the view that which things there is something it is like to be is up to us to stipulate; 2) anti-reductionism about phenomenal consciousness — roughly, the view that phenomenal properties are not reducible to material properties; 3) anti-reductionism about the direction of time — roughly, the view that there exists a primitive time-ordering field which intrinsically distinguishes the past from the future; and 4) radical phenomenal vehicle externalism – roughly, the view that the vehicles of the experiences we call `ours’ actually extend back into the far reaches of the early universe, before the galaxies were formed.
What is it Like to be AlphaGo?
The robots will probably be conscious one day, but what if they are already conscious today? Here I explore the leading reasons for dismissing this possibility and find them wanting. I conclude that it is a live possibility that implementations of leading contemporary AI algorithms (like AlphaGo or AlphaZero) are phenomenally conscious.
