Famous quotes containing the word activity:

    “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.)

    “To play is nothing but the imitative substitution of a pleasurable, superfluous and voluntary action for a serious, necessary, imperative and difficult one. At the cradle of play as well as of artistic activity there stood leisure, tedium entailed by increased spiritual mobility, a horror vacui, the need of letting forms no longer imprisoned move freely, of filling empty time with sequences of notes, empty space with sequences of form.”
    —Max J. Friedländer (1867–1958)

    “... the will always wills to do something and thus implicitly holds in contempt sheer thinking, whose whole activity depends on “doing nothing.””
    —Hannah Arendt (1906–1975)
