“It is a rather singular argument to maintain that, because an abuse which has been permitted a temporary existence, cannot be corrected without wounding the interests of those who have profited by it, it ought, therefore, to claim perpetual duration.”

A further quote sometimes purported to be from a speech to Congress, January 7, 1790 purportedly in the Boston Independent Chronicle, January 14, 1790, this is actually a corruption of a statement made in his first State of the Union Address, relating to the need for maintaining governmental troops and military preparedness:
:: A free people ought not only to be armed, but disciplined; to which end a uniform and well-digested plan is requisite; and their safety and interest require that they should promote such manufactories as tend to render them independent of others for essential, particularly military, supplies.
The proper establishment of the troops which may be deemed indispensable will be entitled to mature consideration. In the arrangements which may be made respecting it it will be of importance to conciliate the comfortable support of the officers and soldiers with a due regard to economy.
