Famous quotes containing the words theory, structural and/or proof:

    Many people have an oversimplified picture of bonding that could be called the “epoxy” theory of relationships...if you don’t get properly “glued” to your babies at exactly the right time, which only occurs very soon after birth, then you will have missed your chance.
    Pamela Patrick Novotny (20th century)

    The reader uses his eyes as well as or instead of his ears and is in every way encouraged to take a more abstract view of the language he sees. The written or printed sentence lends itself to structural analysis as the spoken does not because the reader’s eye can play back and forth over the words, giving him time to divide the sentence into visually appreciated parts and to reflect on the grammatical function.
    J. David Bolter (b. 1951)

    The chief contribution of Protestantism to human thought is its massive proof that God is a bore.
