I am more and more convinced that man is a dangerous creature; and that power, whether vested in many or a few, is ever grasping, and, like the grave, cries, “Give, give!”
Authority intoxicates, And makes mere sots of magistrates; The fumes of it invade the brain, And make men giddy, proud, and vain; By this the fool commands the wise, The noble with the base complies, The sot assumes the rule of wit, And cowards make the base submit.
Power tends to Corrupt and absolute power corrupts absolutely. Great men are almost always bad men. . .There is no worse heresy than that the office santifies the holder of it.
Jails are built out of honest men's earnings. Courts are supported from peaceful men's property. Penitentiaries are built by the toil of virtue. Crime never pays its own way. Vice has no hands to work, no head to calculate. Its whole faculty is to corrupt and to waste; and good men, directly or indirectly, foot the bill.
That the corruption of the best thing produces the worst, is grown into a maxim, and is commonly proved, among other instances, by the pernicious effects of superstition and enthusiasm, the corruptions of true religion.
Knowledge is an excellent drug; but no drug has virtue enough to preserve itself from corruption and decay, if the vessel be tainted and impure therein it is put to keep.
Those who have been once intoxicated with power, and have derived any kind of emolument from it, even though for but one year, can never willingly abandon it.
Our Government is the potent, the omnipresent teacher. For good or for ill, it teaches the whole people by its example. Crime is contagious. If the Government becomes a law-breaker, it breeds contempt for law; it invites every man to become a law unto himself; it invites anarchy. To declare that in the administration of the criminal law the end justifies the means -- to declare that the Government may commit crimes in order to secure the conviction of a private criminal -- would bring terrible retribution. Against that pernicious doctrine this Court should resolutely set its face.
The surest way to corrupt a youth is to instruct him to hold in higher esteem those who think alike than those who think differently.

The most awful thing about power is not that it corrupts absolutely but that it makes people so utterly boring, so predictable.
