Understanding consciousness within the known laws...
By CARLO ROVELLI
Abstract: I do not share the feeling that consciousness (whatever this means) cannot be understood in the context of the known physical laws. So far we do not understand it well, but neither do we fully understand thunderstorms, for that matter. I...

Minimal Phenomenal Experience by Thomas Metzinger
By JOHANNES KLEINER
One classical approach to explaining a complex target phenomenon is to define a minimal model - for example, of conscious experience as such. Is “pure awareness” a form of phenomenal character sui generis, which cannot be reductively defined or...

Unfolding Argument - Replies, Comments and Panel...
By JOHANNES KLEINER
Quite recently, an argument has been proposed which aims to show that Integrated Information Theory, and in fact all theories that define consciousness in terms of the mutual interaction of a system’s parts, cannot explain consciousness....

Undecidability, Uncomputability, and Unpredictability Essay Contest (2019-2020)
*On The Limits of Deducibility* by Stefan Weckbach
By STEFAN WECKBACH
Essay Abstract

Decidability, provability, computability and predictability are all instances of *algorithmic determinism*. The crux with the latter is that it a-priori assumes for every mathematically well-posed question that either an...
