is integral to humanity, and to what it means to be “human.” One of the wonders of modern medicine inarguably is the tremendous improvements in understanding our eyes. Secondarily, we have over the past several centuries (at an accelerating pace*) added significantly to our understanding of the many processes and functions connecting to our optical apparatus. It is hard to overestimate this phenomenon’s radically transformative power, manifesting as it has, throughout the human perceptual complex. People see ourselves differently than we ever have (as far as we know). Clearly, evaluating - even deconstructing - this massive change will be in our interests. Vision, remember, is key to our survival. Any modern analysis of the brain, the nervous system, manual responsiveness, gland function, and so on, demonstrates conclusively the experiential, existential primacy of vision for us.** So, before one engages in unequivocal hucksterism, celebrating the impressive products of advances in optical science, as noted the previous section, one should take pause. For every anecdote about successful Lasik surgery, yielding excellent results, we
