Famous quotes containing the words south and/or bay:
“I don’t have any doubts that there will be a place for progressive white people in this country in the future. I think the paranoia common among white people is very unfounded. I have always organized my life so that I could focus on political work. That’s all I want to do, and that’s all that makes me happy.”
—Hettie V., South African white anti-apartheid activist and feminist. As quoted in Lives of Courage, ch. 21, by Diana E. H. Russell (1989)
“The very dogs that sullenly bay the moon from farm-yards in these nights excite more heroism in our breasts than all the civil exhortations or war sermons of the age.”
—Henry David Thoreau (1817–1862)
