If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. Its peculiar character, too, is that no one possesses the less, because every other possesses the whole of it. He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me. That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property.
Now, nothing should be able to harm a man except himself. Nothing should be able to rob a man at all. What a man really has, is what is in him. What is outside of him should be a matter of no importance.

With the abolition of private property, then, we shall have true, beautiful, healthy Individualism. Nobody will waste his life in accumulating things, and the symbols for things. One will live. To live is the rarest thing in the world. Most people exist, that is all.
Harrington has Shewn that Power always follows Property. This I believe to be as infallible a Maxim, in Politicks, as, that Action and Re-action are equal, is in Mechanicks. Nay I believe We may advance one Step farther and affirm that the Ballance of Power in a Society, accompanies the Ballance of Property in Land. The only possible Way then of preserving the Ballance of Power on the side of equal Liberty and public Virtue, is to make the Acquisition of Land easy to every Member of Society: to make a Division of the Land into Small Quantities, So that the Multitude may be possessed of landed Estates. If the Multitude is possessed of the Ballance of real Estate, the Multitude will have the Ballance of Power, and in that Case the Multitude will take Care of the Liberty, Virtue, and Interest of the Multitude in all Acts of Government.
