Answer: If you take the question seriously, it’s not that easy to answer as the word ‘consciousness’ may apply for two ‘items’ whose differentiation is not easy. First make the difference between ‘I feel cold’ and ‘There are 20° C’. The first is a subjective perspective, for which there is never an empirical proof, and the second is an objective perspective, for which there may be an empirical proof, like a thermometre. Consiousness is a word that may apply as much for a subjective as for an objective perspective. ‘I’m conscious of how much trouble this causes’, can not be empirically proved. But consciousness is a function of the brain, too, whose empirical proof is in fact more than negative, in a first approach, – lacking a part of the brain, you can’t be conscious of anything anymore. Starting from there, you can determine which part of the brain is active while the person is conscious and even control the movements of this parts through electromagnetic devices. How much self consciousness can be proved (to be conscious in medical terms applies actually only for the fact of being bioligically aware or able of physical response) is difficult to say.
