Famous quotes containing the words common and/or designs:
“Human life in common is only made possible when a majority comes together which is stronger than any separate individual and which remains united against all separate individuals. The power of this community is then set up as right in opposition to the power of the individual, which is condemned as brute force.”
—Sigmund Freud (18561939)
“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)
