Main Question or Discussion Point
If, in fact we have to rely wholly on sentience in order to interpret our world, why should we deem sentience circular? If so, then our attempts to define who and what we are -- or, for that matter, anything -- is worthless. And, while we may stress the need for "empirical evidence," who or what is it that stresses it? Is it anything other than what we observe personally, inside our own minds?
