BB Post: as Embers of Servetus. More on ego, autonomy, consciousness

While it is certainly true that consciousness and behavior, and brain-function in general, is far more complex than most people realize, I don't think even the brightest people in neuroscience and neuropsychology have a good enough handle on the brain to be able to justify the hypothesis that the subjective sensation and intuition of conscious autonomy is an illusion.

There have been many studies over the past few decades, most notably by Benjamin Libet, which indicate that the sensation of being conscious of making a choice actually occurs after the brain has already made the decision: that the sense of autonomy is a sort of constantly updated narrative conducted by the brain to afford a feeling of self-control and free agency when in fact there is no control or free agency (freewill). Despite the seemingly overwhelming data giving credence to this idea, I don't buy it. And there are still plenty of well-credited scientists and psychologists who don't buy it either.

 I'm with thinkers like David Chalmers and John Searle when it comes to consciousness and behavior: I think what causes consciousness in the brain's mechanism is not yet understood, in fact I think we are far from grasping it. This is what keeps the field of A.I. in a sort of limbo: the inability to manufacture anything like sentience or consciousness in a machine. I believe nature's technology is many orders of magnitude more advanced than man's technology, and it's sheer arrogance to think that since we can't fully understand how consciousness, high intelligence, and free agency arises in humans, then the normal (not to mention manifestly common across generations, nations, and cultures) sensation of autonomy and self-generated action, as well as the ego and sense of self and identity, is "an illusion".
