“But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself.”  – James Madison.

I like this quote as it succinctly describes the difference between those that want central government and those that want limited government.  We can argue if the federal government should get involved in healthcare, roads, energy policy, etc, but the practical problem that we are attempting to solve as a society should not neglect the wisdom of our founding fathers.

(Thank you to American Majority for highlighting this quote).
