I think its problematic to refer to an emergent property without first defining this property and identifying at what stage it emerges.
I did those things. Please re-read my posts. There are emergent properties at every level of organization from atom, to molecule, to organelle, to cell, to tissue, to organ, etc.
You keep asking how many parts of a whole it takes for a property of the whole to emerge, and I keep pointing out that it's not a question of quantity.
The question of Penrose and his thesis on QM being capable of explaining consciousness ?
Your question makes no sense. ( In fact, it's a sentence fragment, so I'm not even sure how to parse it.) I asked whether QM or neuroscience is more likely to lead to new knowledge about consciousness.
I do not believe it is consciousness that needs explaining, but thinking.
This can only be explained using thinking. We can confirm our thoughts on consciousness using the scientific method. In other words consciousness is a question for philosophy to unravel and science to communicate.
I disagree. We know many of the components of consciousness (memory, arousal, proprioception, nociception, language, etc.), and we can localize those functions to specific brain structures. Neuroscience promises to unravel more of the unknowns in this area.
In fact, as much as I enjoy philosophy and logic, deductive logic can't lead to new knowledge on its own. Logic can only lead you to information that is already there in the premises.
