Famous quotes containing the words current and/or symbols:

    What in fact have I achieved, however much it may seem? Bits and pieces ... trivialities. But here they won’t tolerate anything else, or anything more. If I wanted to take one step in advance of the current views and opinions of the day, that would put paid to any power I have. Do you know what we are ... those of us who count as pillars of society? We are society’s tools, neither more nor less.
    Henrik Ibsen (1828–1906)

    And into the gulf between cantankerous reality and the male ideal of shaping your world, sail the innocent children. They are right there in front of us—wild, irresponsible symbols of everything else we can’t control.
    Hugh O’Neill (20th century)
