“To execute laws is a royal office; to execute orders is not to be a king. However, a political executive magistracy, though merely such, is a great trust.”

1870s, Eighth State of the Union Address (1876)
Context: It was my fortune, or misfortune, to be called to the office of Chief Executive without any previous political training. From the age of 17 I had never even witnessed the excitement attending a Presidential campaign but twice antecedent to my own candidacy, and at but one of them was I eligible as a voter.
Under such circumstances it is but reasonable to suppose that errors of judgment must have occurred. Even had they not, differences of opinion between the Executive, bound by an oath to the strict performance of his duties, and writers and debaters must have arisen. It is not necessarily evidence of blunder on the part of the Executive because there are these differences of views. Mistakes have been made, as all can see and I admit...

Context: The militia and sovereignty are inseparable. In the English constitution, if the whole nation were a militia, there would be a militia to defend the crown, the lords, or the commons, if either were attacked. The crown, though it commands them, has no power to use them improperly, because it cannot pay or subsist them without the consent of the lords and commons; but if the militia are to obey a sovereignty in a single assembly, it is commanded, paid, and subsisted, and a standing army, too, may be raised, paid, and subsisted, by the vote of a majority; the militia, then, must all obey the sovereign majority, or divide, and part follow the majority, and part the minority. This last case is civil war; but, until it comes to this, the whole militia may be employed by the majority in any degree of tyranny and oppression over the minority. The constitution furnishes no resource or remedy; nothing affords a chance of relief but rebellion and civil war. If this terminates in favor of the minority, they will tyrannize in their turn, exasperated by revenge, in addition to ambition and avarice; if the majority prevail, their domination becomes more cruel, and soon ends in one despot. It must be made a sacred maxim, that the militia obey the executive power, which represents the whole people in the execution of laws. To suppose arms in the hands of citizens, to be used at individual discretion, except in private self-defence, or by partial orders of towns, counties, or districts of a state, is to demolish every constitution, and lay the laws prostrate, so that liberty can be enjoyed by no man; it is a dissolution of the government. The fundamental law of the militia is, that it be created, directed, and commanded by the laws, and ever for the support of the laws.
