Light Receptors

Famous quotes containing the words light and/or receptors:

    In the early days of the world, the Almighty said to the first of our race “In the sweat of thy face shalt thou eat bread”; and since then, if we except the light and the air of heaven, no good thing has been, or can be enjoyed by us, without having first cost labour.
    Abraham Lincoln (1809–1865)

    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)
