To consider judges as the ultimate arbiters of all constitutional questions is a very dangerous doctrine indeed, and one which would place us under the despotism of an oligarchy.
- Thomas Jefferson
The President may have a great many powers given to him by the Constitution and may have certain powers under certain laws which are given to him by the Congress of the United States; but the principal power that the President had is to bring people in and try to persuade them to do what they ought to do without persuasion.
- Harry S. Truman
The government is everywhere sovereign in the state, and the constitution is in fact the government.
- Aristotle
It was settled by the Constitution, the laws, and the whole practice of the government that the entire executive power is vested in the President of the United States.
