Holographic Duality and the Physics of Consciousness

This paper introduces a novel dual-aspect theory of consciousness that is based on the principle of holographic-duality in modern physics and explores the prospects of making philosophically significant ...
I will argue that abstract algorithms are not enough to solve this problem and that a more radical "computation" that is inspired by physics and that can be realized in "strange metals" may be needed. ...
