    the moderate Aristotelian city
    Of darning and the Eight-Fifteen, where Euclid’s geometry
    And Newton’s mechanics would account for our experience,
    And the kitchen table exists because I scrub it.
    —W.H. (Wystan Hugh)

    ...a fixed aim furnishes us with a fixed measure, by which we can decide whether such or such an action proposed is worth trying for or not, and as aims must vary with the individual, the decisions of any two people as to the desirableness of an action may not be the same.
    Anna C. Brackett (1836–1911)

    Science is feasible when the variables are few and can be enumerated; when their combinations are distinct and clear. We are tending toward the condition of science and aspiring to do it. The artist works out his own formulas; the interest of science lies in the art of making science.
    Paul Valéry (1871–1945)
