Emergence/Consciousness/Chalmers: it is sometimes asked why I do not assume that consciousness emerges from physical facts.
ChalmersVsEmergence: the well-known examples of emergence, e.g. Self-organization in biological systems or patterns in bird flocks are not analogous to consciousness.
Consciousness: should be emergent in a much stronger sense. E.g. Broad 1925:
Emergence/Broad: According to his thesis, emergent properties are not even predictable from all known physical properties of a more basic level.
ChalmersVsBroad: this is a strong variant of the property dualism.
It would require additional fundamental laws.
