The acts of the mind, wherein it exerts its power over simple ideas, are chiefly these three: 1. Combining several simple ideas into one compound one, and thus all complex ideas are made. 2. The second is bringing two ideas, whether simple or complex, together, and setting them by one another so as to take a view of them at once, without uniting them into one, by which it gets all its ideas of relations. 3. The third is separating them from all other ideas that accompany them in their real existence: this is called abstraction, and thus all its general ideas are made.
John LockeFrom whence it is obvious to conclude that, since our Faculties are not fitted to penetrate into the internal Fabrick and real Essences of Bodies; but yet plainly discover to us the Being of a GOD, and the Knowledge of our selves, enough to lead us into a full and clear discovery of our Duty, and great Concernment, it will become us, as rational Creatures, to imploy those Faculties we have about what they are most adapted to, and follow the direction of Nature, where it seems to point us out the way.
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 LockeWhensoever, therefore, the legislative shall transgress this fundamental rule of society, and either by ambition, fear, folly, or corruption, endeavour to grasp themselves, or put into the hands of any other, an absolute power over the lives, liberties, and estates of the people, by this breach of trust they forfeit the power the people had put into the hands... and it devolves to the people, who have a right to resume their original liberty, and... provide for their own safety and security.
