Famous quotes containing the words sensory and/or biology:
“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)
“The “control of nature” is a phrase conceived in arrogance, born of the Neanderthal age of biology and the convenience of man.”
