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)

    The extra worry began it—on the
    Blue blue mountain—she never set foot
    And then and there. Meanwhile the host
    Mourned her quiet tenure. They all stayed chatting.
    No one did much about eating.
    John Ashbery (b. 1927)

    No one thinks anything silly is suitable when they are an adolescent. Such an enormous share of their own behavior is silly that they lose all proper perspective on silliness, like a baker who is nauseated by the sight of his own eclairs. This provides another good argument for the emerging theory that the best use of cryogenics is to freeze all human beings when they are between the ages of twelve and nineteen.
    Anna Quindlen (20th century)
