“To govern is to choose.”

1962, Address at Independence Hall
Context: The necessity for comity between the National Government and the several States is an indelible lesson of our long history. Because our system is designed to encourage both differences and dissent, because its checks and balances are designed to preserve the rights of the individual and the locality against preeminent central authority, you and I, Governors, recognize how dependent we both are, one upon the other, for the successful operation of our unique and happy form of government. Our system and our freedom permit the legislative to be pitted against the executive, the State against the Federal Government, the city against the countryside, party against party, interest against interest, all in competition or in contention one with another. Our task — your task in the State House and my task in the White House — is to weave from all these tangled threads a fabric of law and progress. We are not permitted the luxury of irresolution. Others may confine themselves to debate, discussion, and that ultimate luxury — free advice. Our responsibility is one of decision — for to govern is to choose.

Independence Day speech (1828)
Context: Americans no longer argue on the propriety of making all men soldiers, in order that their nation may be an object of terror to the rest of the world. They understand that the happiness of a people is the only rational object of a government, and the only object for which a people, free to choose, can have a government at all. They have, farther, almost excluded war as a profession, and reduced it from a system of robbery to one of simple defence. In so doing, they ought also to have laid aside all show of military parade, and all ideas of military glory. If they have not done so, it is that their reform in this matter is yet imperfect, and their ideas respecting it are confused.
