The patent act uses the phrase 'useful invention' merely incidentally. ... All that the law requires is, that the invention should not be frivolous o… - Joseph Story

The militia is the natural defence of a free country against sudden foreign invasions, domestic insurrections, and domestic usurpations of power by rulers. It is against sound policy for a free people to keep up large military establishments and standing armies in time of peace, both from the enormous expenses, with which they are attended, and the facile means, which they afford to ambitious and unprincipled rulers, to subvert the government, or trample upon the rights of the people. The right of the citizens to keep and bear arms has justly been considered, as the palladium of the liberties of a republic; since it offers a strong moral check against the usurpation and arbitrary power of rulers; and will generally, even if these are successful in the first instance, enable the people to resist and triumph over them. And yet, though this truth would seem so clear, and the importance of a well regulated militia would seem so undeniable, it cannot be disguised, that among the American people there is a growing indifference to any system of militia discipline, and a strong disposition, from a sense of its burthens, to be rid of all regulations. How it is practicable to keep the people duly armed without some organization, it is difficult to see. There is certainly no small danger, that indifference may lead to disgust, and disgust to contempt; and thus gradually undermine all the protection intended by this clause of our national bill of rights.

Thus, the whole power over the subject of religion is left exclusively to the state government, to be acted upon according to their own sense of justice, and the state constitutions; and the Catholic and the Protestant, the Calvinist and the Arminian, the Jew and the Infidel, may sit down at the common table of the national councils, without any inquisition into their faith, or mode of worship.

I am not able to understand how it can be correctly said in a legal sense, that an action will not lie even in the case of a wrong or a violation of a right, unless it is followed by some perceptible damage which can be established as a matter of fact; in other words, that injuria sine damno is not actionable. On the contrary, from my earliest reading I have considered it laid up among the very elements of the common law, that wherever there is a wrong there is a remedy to redress it; and that every injury imports damage in the nature of it; and if no other damage is established, the party injured is entitled to a verdict for nominal damages.
