Famous quotes containing the words common and/or designs:
“Nothing shall warp me from the belief that every man is a lover of truth. There is no pure lie, no pure malignity in nature. The entertainment of the proposition of depravity is the last profligacy and profanation. There is no scepticism, no atheism but that. Could it be received into common belief, suicide would unpeople the planet.”
—Ralph Waldo Emerson (18031882)
“I have no designs on society, or nature, or God. I am simply what I am, or I begin to be that. I live in the present. I only remember the past, and anticipate the future. I love to live.”
—Henry David Thoreau (18171862)
