Article 1, Section 8, Clause 15
Federal Farmer, no. 1825 Jan. 1788Storing 2.8.217
These corps, not much unlike regular troops, will ever produce an inattention to the general militia; and the consequence has ever been, and always must be, that the substantial men, having families and property, will generally be without arms, without knowing the use of them, and defenceless; whereas, to preserve liberty, it is essential that the whole body of the people always possess arms, and be taught alike, especially when young, how to use them; nor does it follow from this, that all promiscuously must go into actual service on every occasion. The mind that aims at a select militia, must be influenced by a truly anti-republican principle; and when we see many men disposed to practice upon it, whenever they can prevail, no wonder true republicans are for carefully guarding against it. As a farther check, it may be proper to add, that the militia of any state shall not remain in the service of the union, beyond a given period, without the express consent of the state legislature.
