And do you seriously think that a brain surgeon or heart surgeon are only aware of an incision AFTER they have made it?
Its not just surgeons, every living thing with a brain
experiences life subject to a small time lag; brains need a certain amount of time to construct a coherent and clear composited stream of awareness. Conscious experience is a massively sophisticated phenomenon coordinating multiple different information streams. I know we tend to take it all for granted, but then maybe we are being lazy in that. Start from a baseline of fundamental physics - there is no such thing as
instantaneous; Einstein showed us that there is an finite limit to the speed of information transfer - light speed. Speeds of neural transmission are far slower than that, with chemical messaging across synaptic gaps slowing the propagation of thoughts immensely and given that brains are processing literally billions of such events every second, even when sleeping, I find it staggering that our time lag is in fact so small as 400ms or thereabouts. So, for your surgeon, he formed an intention to make an incision before he '
knew' he formed it, and he made the incision before he '
knew' that he had made it.
I agree, nonetheless, this is counterintuitive, but hey, that is why we do science, to expose the actualities that underpin our common perceptions of what reality is like.
