As usurpation is the exercise of power which another has a right to, so tyranny is the exercise of power beyond right, which nobody can have a right to.
John LockeTis a Mistake to think this Fault [tyranny] is proper only to Monarchies; other Forms of Government are liable to it, as well as that. For where-ever the Power that is put in any hands for the Government of the People, and the Preservation of their Properties, is applied to other ends, and made use of to impoverish, harass, or subdue them to the Arbitrary and Irregular Commands of those that have it: There it presently becomes Tyranny, whether those that thus use it are one or many.
John LockeThe Bible is one of the greatest blessings bestowed by God on the children of men. It has God for its author; salvation for its end, and truth without any mixture for its matter. It is all pure.
