Were the brain a system with feedback (which undoubtedly it is) then what would its fixed-point be like? That is with full feedback the mind comes to a stable state where the input does not stimulate any changes in the brain. Sound familiar? Isn't this a meditation state of mental stillness.
Reading more Smullyan on self-reference last night this feature of fixed-points did seem to capture something about the mind. I don't see how feedback creates consciousness, but I do see how finding the fixed point of the brain tells us (as minds) what the essence of our brain is and draws attention to our pure-mind.
I shall meditate on this at some stage and see if I actually do find a fixed-point.
