    The Good of man is the active exercise of his soul’s faculties in conformity with excellence or virtue.... Moreover this activity must occupy a complete lifetime; for one swallow does not make spring, nor does one fine day; and similarly one day or a brief period of happiness does not make a man supremely blessed and happy.
    Aristotle (384–322 B.C.)

    Psychology keeps trying to vindicate human nature. History keeps undermining the effort.
    Mason Cooley (b. 1927)
