Famous quotes containing the word activity:

    ... 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)

    I suspect there isn’t an actor alive who was able to truthfully answer his family’s questions after his first day’s activity in his future profession.
    Simone Signoret (1921–1985)

    The mob is man voluntarily descending to the nature of the beast. Its fit hour of activity is night. Its actions are insane like its whole constitution. It persecutes a principle; it would whip a right; it would tar and feather justice, by inflicting fire and outrage upon the houses and persons of those who have these. It resembles the prank of boys, who run with fire-engines to put out the ruddy aurora streaming to the stars.
    Ralph Waldo Emerson (1803–1882)
