As it is in the body, so it is in the mind; practice makes it what it is, and most even of those excellencies, what are looked on as natural endowments, will be found, when examined into more narrowly, to be the product of exercise, and to be raised to that pitch, only by repeated actions.
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.
