Symbolic Logic

Famous quotes containing the words symbolic and/or logic:

    An ancient bridge, and a more ancient tower,
    A farmhouse that is sheltered by its wall,
    An acre of stony ground,
    Where the symbolic rose can break in flower,
    Old ragged elms, old thorns innumerable....
    William Butler Yeats (1865–1939)

    Neither Aristotelian nor Russellian rules give the exact logic of any expression of ordinary language; for ordinary language has no exact logic.
    Sir Peter Frederick Strawson (b. 1919)
