In conjunction with the publication of Chapter 11 of Business Law Basics, a round-up of quotes about the U.S. Constitution:

“I know no safe depository of the ultimate powers of the society but the people themselves; and if we think them not enlightened enough to exercise their control with a wholesome discretion, the remedy is not to take it from them but to inform their discretion by education. This is the true corrective of abuses of Constitutional power.”
― Thomas Jefferson

“I believe there are more instances of the abridgment of the freedom of the people by gradual and silent encroachments of those in power than by violent and sudden usurpations.”
― James Madison

"The Constitution of the United States was made not merely for the generation that then existed, but for posterity- unlimited, undefined, endless, perpetual posterity."
― Henry Clay

“I will, to the best of my ability, preserve, protect and defend the Constitution of the United States. It is not the Constitution as I would like to have it, but as it is, that is to be defended. The Constitution will not be preserved & defended until it is enforced & obeyed in every part of every one of the United States. It must be so respected, obeyed, enforced and defended, and let the grass grow where it may.”
― Abraham Lincoln

"If there is any principle of the Constitution that more imperatively calls for attachment than any other it is the principle of free thought, not free thought for those who agree with us but freedom for the thought that we hate."
― Oliver Wendell Holmes
