Famous quotes containing the words current and/or electric:

    Talent develops in quiet places, character in the full current of human life.
    Johann Wolfgang Von Goethe (1749–1832)

    The family circle has widened. The worldpool of information fathered by the electric media—movies, Telstar, flight—far surpasses any possible influence mom and dad can now bring to bear. Character no longer is shaped by only two earnest, fumbling experts. Now all the world’s a sage.
    Marshall McLuhan (1911–1980)
