Sect. 143. The legislative power is that, which has a right to direct how the force of the commonwealth shall be employed for preserving the community and the members of it. . . . Sect. 144. But because the laws, that are at once, and in a short time made, have a constant and lasting force, and need a perpetual execution, or an attendance thereunto; therefore it is necessary there should be a power always in being, which should see to the execution of the laws that are made, and remain in force. And thus the legislative and executive power come often to be separated.
Though, as I said, the executive and federative power of every community be really distinct in themselves, yet they are hardly to be separated, and placed at the same time, in the hands of distinct persons: for both of them requiring the force of the society for their exercise, it is almost impracticable to place the force of the commonwealth in distinct, and not subordinate hands; or that the executive and federative power should be placed in persons, that might act separately, whereby the force of the public would be under different commands: which would be apt some time or other to cause disorder and ruin.
And thus the community perpetually retains a supreme power of saving themselves from the attempts and designs of any body, even of their legislators, whenever they shall be so foolish, or so wicked, as to lay and carry on designs against the liberties and properties of the subject: . . . when ever any one shall go about to bring them into such a slavish condition, they will always have a right to preserve, what they have not a power to part with; and to rid themselves of those, who invade this fundamental, sacred, and unalterable law of self-preservation, for which they entered into society.
I say, using force upon the people without authority, and contrary to the trust put in him that does so, is a state of war with the people, who have a right to reinstate their legislative in the exercise of their power: for having erected a legislative, with an intent they should exercise the power of making laws, either at certain set times, or when there is need of it, when they are hindered by any force from what is so necessary to the society, and wherein the safety and preservation of the people consists, the people have a right to remove it by force.
