Famous quotes containing the word discussion:
“Americans, unhappily, have the most remarkable ability to alchemize all bitter truths into an innocuous but piquant confection and to transform their moral contradictions, or public discussion of such contradictions, into a proud decoration, such as are given for heroism on the battle field.”
—James Baldwin (1924–1987)
“The whole land seems aroused to discussion on the province of woman, and I am glad of it. We are willing to bear the brunt of the storm, if we can only be the means of making a break in that wall of public opinion which lies right in the way of woman’s rights, true dignity, honor and usefulness.”

I cannot believe that such a programme would be rejected by the people of this country, even if it does mean the establishment of personal contact with the dictators.”
—Neville Chamberlain (1869–1940)
