There is no doubt that small structures exhibit quantum effects. There is absolutely no demonstrable relationship between small things exhibiting quantum effects and consciousness.

You give your whole game away when you say

’which is needed for consciousness to "limit" itself to an identity.’

This is actually mysticism. You’re already making absolutely extreme claims for what you believe consciousness to be.

It may well be that consciousness is ‘in the microtubules’. But today we have no evidence of this. Nor do we have effective understandings of why anaesthetic drugs work (as opposed to, say, our mechanistic understanding of how opioids cause analgesia, or other pharmapsychophysiological relationships).

Keep an open mind, but don’t let your brain fall out
