2. According to the definition of liberty above given, freedom, that is free agency, is applicable to mind as well as to matter. Free-will does not, because will does not, belong to it. By a free agent, I understand, with Hobbes, one that is not hindered from acting according to his natural or determinate bias. The body is free when it can obey the impulse of the mind; so also a billiard-ball might be said to be free while it is not fixed to the table, or hindered from being impelled by the stroke of the mace. In the same sense, the water, as Mr. Hobbes observes, is said to descend freely along the channel of the river, while no obstacle intercepts its progress. But though necessarians allow liberty to the body, and to inanimate things, they deny that it is in any sense applicable to the mind or will. ON LOCKE’S ESSAY ON THE HUMAN UNDERSTANDING This work owes its present rank among philosophical productions, to its embodiment of the great principle first brought forward by Hobbes. All its author’s attempts to modify this principle or reconcile it to common notions have been gradually exploded, and have given place to the more severe and logical deductions of Hobbes from the same general principle. Mr. Locke took the faculties of the mind as he found them in himself and others, and endeavoured to account for them on _a new principle_. By this compromise with candour and common sense, he prepared the way for the introduction of the principle, which being once established, very soon overturned all the trite opinions and vulgar prejudices which were improperly associated with it. There was in fact no place for them in the new system.
