Famous quotes containing the words inborn, errors and/or metabolism:

    Temperament is the natural, inborn style of behavior of each individual. It’s the how of behavior, not the why.... The question is not, “Why does he behave a certain way if he doesn’t get a cookie?” but rather, “When he doesn’t get a cookie, how does he express his displeasure...?” The environment—and your behavior as a parent—can influence temperament and interplay with it, but it is not the cause of temperamental characteristics.
    Stanley Turecki (20th century)

    When a Man is in a serious Mood, and ponders upon his own Make, with a Retrospect to the Actions of his Life, and the many fatal Miscarriages in it, which he owes to ungoverned Passions, he is then apt to say to himself, That Experience has guarded him against such Errors for the future: But Nature often recurs in Spite of his best Resolutions, and it is to the very End of our Days a Struggle between our Reason and our Temper, which shall have the Empire over us.
    Richard Steele (1672–1729)

    He’s got a fifteen percent metabolism with an overactive thyroid and a glandular affectation of about three percent. With a one percent mentality. He’s what we designate as the Crummy Moronic type.
