Mankind censure injustice fearing that they may be the victim of it, and not because they shrink from committing it. The state, it cannot be too often repeated, does nothing and can give nothing which it has not taken from somebody. A government big enough to give you everything you want is a government big enough to take from you everything you have. The liberty of a democracy is not safe if the people tolerate the growth of private power to a point where it becomes stronger than their democratic State itself. That, in its essence, is Fascism - ownership of government by an individual, by a group, or any controlling private power.
Power is a means to an end.
Power tends to corrupt, and absolute power corrupts absolutely. Power must never be trusted without a check. Power corrupts the few, but weakness corrupts the many. If power corrupts, weakness in the seat of power, with its constant necessity of deals and bribes and compromising arrangements, corrupts even more. In every age the vilest specimens of human nature are to be found among demagogues.
