Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    “The host, the housekeeper, it is
    who fails you. He had forgotten
    to make room for you at the hearth
    or set a place for you at the table
    or leave the doors unlocked for you.”
    —Denise Levertov (b. 1923)

    “We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fall—which latter, it would seem, is now near, among all people.”
    —Thomas Carlyle (1795–1881)
