Famous quotes containing the words receptors and/or present:
“Our talk of external things, our very notion of things, is just a conceptual apparatus that helps us to foresee and control the triggerings of our sensory receptors in the light of previous triggering of our sensory receptors.”
—Willard Van Orman Quine (b. 1908)
“An oblong puddle inset in the coarse asphalt; like a fancy footprint filled to the brim with quicksilver; like a spatulate hole through which you can see the nether sky. Surrounded, I note, by a diffuse tentacled black dampness where some dull dun dead leaves have stuck. Drowned, I should say, before the puddle had shrunk to its present size.”
—Vladimir Nabokov (1899–1977)
