As much land as a man tills, plants, improves, cultivated, and can use the product of, so much is his property. He by his labour does, as it were, enclose it from the common.
John LockeSo difficult it is to show the various meanings and imperfections of words when we have nothing else but words to do it with.
John LockeThe 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 LockeThe state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it.
John LockeThere cannot any one moral rule be proposed whereof a man may not justly demand a reason. Every man has a property in his own person. This nobody has any right to but himself. The people cannot delegate to government the power to do anything which would be unlawful for them to do themselves.
