Famous quotes containing the word action:

    “Rash actions are seldom committed in isolation. With the first rash action we always do too much. So we usually go on to commit a second one—and then we do too little.”
    —Friedrich Nietzsche (1844–1900)

    “The action of the soul is oftener in that which is felt and left unsaid, than in that which is said in any conversation. It broods over every society, and they unconsciously seek for it in each other.”
    —Ralph Waldo Emerson (1803–1882)

    “For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
    —Selma H. Fraiberg (20th century)
