“Governments which have a regard to the common interest are constituted in accordance with strict principles of justice, and are therefore true forms; but those which regard only the interest of the rulers are all defective and perverted forms, for they are despotic, whereas a state is a community of freemen.”
—Aristotle (384–322 B.C.)
“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.”
