Famous quotes containing the words dark and/or matter:
“When I consider how my light is spent,
Ere half my days, in this dark world and wide,
And that one talent which is death to hide
Lodged with me useless.”

“During those years in Stamps, I met and fell in love with William Shakespeare. He was my first white love.... it was Shakespeare who said, “When in disgrace with fortune and men’s eyes.” It was a state of mind with which I found myself most familiar. I pacified myself about his whiteness by saying that after all he had been dead so long it couldn’t matter to anyone any more.”
—Maya Angelou (b. 1928)
