Famous quotes containing the words features and/or version:

    “Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
    —Henry David Thoreau (1817–1862)

    “Truth cannot be defined or tested by agreement with ‘the world’; for not only do truths differ for different worlds but the nature of agreement between a world apart from it is notoriously nebulous. Rather—speaking loosely and without trying to answer either Pilate’s question or Tarski’s—a version is to be taken to be true when it offends no unyielding beliefs and none of its own precepts.”
    —Nelson Goodman (b. 1906)
