"Not so many years ago this was a mistake that brain scientists actually made: they succumbed all too often to the temptation to treat vision as if it were television — as if it were simply a matter of getting "the picture" from the eyes to the screen somewhere in the middle where it could be handsomely reproduced so that the phenomena of appreciation and analysis could then get underway. Today we realize that the analysis — the whatever you want to call it that composes, in the end, all the visual understanding — begins right away, on the retina; if you postpone consideration of it, you misdescribe how vision works."

"You’re actually socially isolating yourself with your phone. I feel like it’s kind of emasculating. This Google Glass really takes away that excuse.… It really opened my eyes to how much of my life I spent secluded away in email or social posts. My vision when we started Google 15 years ago was that eventually you wouldn’t have to have a search query at all — the information would just come to you as you needed it. This is the first form factor that can deliver that vision."

"Are they shadows that we see? And can shadows pleasure give? Pleasures only shadows be, Cast by bodies we conceive, And are made the things we deem In those figures which they seem.But these pleasures vanish fast Which by shadows are expressed: Pleasures are not, if they last, In their passing, is their best: Glory is most bright and gay In a flash, and so away.Feed apace then, greedy eyes, On the wonder you behold; Take it sudden as it flies, Though you take it not to hold: When your eyes have done their part, Thought must length it in the heart."

"The "prevalence of the gaze," or the privileging of the visual, as the primary means to knowledge in Western scientific and philosophical traditions has been the subject of a feminist inquiry by Evelyn Fox Keller and Christine R. Grontkowski. In their analysis, stretching from Plato to Bacon and Descartes, this emphasis on the visual has had a paradoxical function. For sight, in contrast to the other senses, has as its peculiar property the capacity for detachment, for objectifying the thing visualized by creating distance between knower and known. (In modern optics, the eye becomes a passive recorder, a camera obscura.) In this way, the elevation of the visual in a hierarchy of senses actually has the effect of debasing sensory experience, and relatedness, as modes of knowing:" Vision connects us to truth as it distances us from the corporeal."
