Famous quotes containing the words forces and/or reaction:

    The popularity of disaster movies ... expresses a collective perception of a world threatened by irresistible and unforeseen forces which nevertheless are thwarted at the last moment. Their thinly veiled symbolic meaning might be translated thus: We are innocent of wrongdoing. We are attacked by unforeseeable forces come to harm us. We are, thus, innocent even of negligence. Though those forces are insuperable, chance will come to our aid and we shall emerge victorious.
    David Mamet (b. 1947)

    In contrast to revenge, which is the natural, automatic reaction to transgression and which, because of the irreversibility of the action process can be expected and even calculated, the act of forgiving can never be predicted; it is the only reaction that acts in an unexpected way and thus retains, though being a reaction, something of the original character of action.
    Hannah Arendt (1906–1975)
