That was an expression of doubt, or of skepticism, not an argument. However, the very fact that consciousness resisted for so long to scientific explanation is a strong evidence that it, indeed, escapes material explanations. It's the fact that all of science deals with quantitative expressions and measurements, whereas consciousness is qualitative. We don't know what it like to be a bat, me as a man I don't know what is it like to be a woman, nor does my wife know what it is like to be a man, or someone else for that matter. Only for the simple reason that qualitative experiences, in themselves, are subjective and bound to the subject experiencing them. How do we know the electrons don't feel? We don't. Some, like me, presume they don't. Others, in panpsychism, presume they do. At little tiny bit, at least. >> Not to mention, as far as we can tell, we are machines. That is a very strong statement.
