Famous quotes containing the words biological and/or material:
“I am fifty-two years of age. I am a bishop in the Anglican Church, and a few people might be constrained to say that I was reasonably responsible. In the land of my birth I cannot vote, whereas a young person of eighteen can vote. And why? Because he or she possesses that wonderful biological attribute—a white skin.”
—Desmond Tutu (b. 1931)
“This is no war for domination or imperial aggrandisement or material gain.... It is a war ... to establish, on impregnable rocks, the rights of the individual and it is a war to establish and revive the stature of man.”
—Winston Churchill (1874–1965)
