Famous quotes containing the words black and/or facsimile:
“It’s not like I was out there running and not knowing what’s going on in the country. I knew what was going on, but I felt this is not something that is going to bog me down and not let me participate. The only way I was going to make a difference for myself or any other black person is to say the hurdles were there and do what I had to do.”
—Wyomia Tyus (b. 1945)
“God gave the righteous man a certificate entitling him to food and raiment, but the unrighteous man found a facsimile of the same in God’s coffers, and appropriated it, and obtained food and raiment like the former. It is one of the most extensive systems of counterfeiting that the world has seen.”
—Henry David Thoreau (1817–1862)
