Those who have been once intoxicated with power and have derived any kind of emolument from it can never willingly abandon it.
Edmund Burke (1729-1797)
If once the people become inattentive to the public affairs, you and I, and Congress and Assemblies, Judges and Governors, shall all become wolves. It seems to be the law of our general nature, in spite of individual exceptions.
Thomas Jefferson (1743-1826)
