Famous quotes containing the words constructive, set and/or theory:

    Once we begin to appreciate that the apparent destructiveness of the toddler in taking apart a flower or knocking down sand castles is in fact a constructive effort to understand unity, we are able to revise our view of the situation, moving from reprimand and prohibition to the intelligent channeling of his efforts and the fostering of discovery.
    Polly Berrien Berends (20th century)

    They roused him with muffins—they roused him with ice—
    They roused him with mustard and cress—
    They roused him with jam and judicious advice—
    They set him conundrums to guess.
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fall—which latter, it would seem, is now near, among all people.
    Thomas Carlyle (1795–1881)
