Famous quotes containing the words theory and/or neutral:

    The theory of truth is a series of truisms.
    —J.L. (John Langshaw)

    The seashore is a sort of neutral ground, a most advantageous point from which to contemplate this world. It is even a trivial place. The waves forever rolling to the land are too far-traveled and untamable to be familiar. Creeping along the endless beach amid the sun-squall and the foam, it occurs to us that we, too, are the product of sea-slime.
    Henry David Thoreau (1817–1862)
