Famous quotes containing the words spectral, theory, ordinary, differential and/or classical:

    “How does one kill fear, I wonder? How do you shoot a spectre through the heart, slash off its spectral head, take it by its spectral throat?”

    “Psychotherapy—The theory that the patient will probably get well anyway, and is certainly a damned ijjit.”
    —H.L. (Henry Lewis)

    “It’s an ordinary day for Brian. Like, he died every day, you know.”
    —Pete Townshend (b. 1945)

    “But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
    —Antonin Artaud (1896–1948)

    “Culture is a sham if it is only a sort of Gothic front put on an iron building—like Tower Bridge—or a classical front put on a steel frame—like the Daily Telegraph building in Fleet Street. Culture, if it is to be a real thing and a holy thing, must be the product of what we actually do for a living—not something added, like sugar on a pill.”
    —Eric Gill (1882–1940)
