Famous quotes containing the words effective and/or theories:
“Fine art is the subtlest, the most seductive, the most effective instrument of moral propaganda in the world, excepting only the example of personal conduct; and I waive even this exception in favor of the art of the stage, because it works by exhibiting examples of personal conduct made intelligible and moving to crowds of unobservant unreflecting people to whom real life means nothing.”
—George Bernard Shaw (1856–1950)
“The two most far-reaching critical theories at the beginning of the latest phase of industrial society were those of Marx and Freud. Marx showed the moving powers and the conflicts in the social-historical process. Freud aimed at the critical uncovering of the inner conflicts. Both worked for the liberation of man, even though Marx’s concept was more comprehensive and less time-bound than Freud’s.”
—Erich Fromm (1900–1980)
