No power but Congress can declare war; but what is the value of this constitutional provision, if the President of his own authority may make such military movements as must bring on war? ... [T]hese remarks originate purely in a desire to maintain the powers of government as they are established by the Constitution between the different departments, and hope that, whether we have conquests or no conquests, war or no war, peace or no peace, we shall yet preserve, in its integrity and strength, the Constitution of the United States.

Nothing is more deceptive or more dangerous than the pretence of a desire to simplify government. The simplest governments are despotisms; the next simplest, limited monarchies; but all republics, all governments of law, must impose numerous limitations and qualifications of authority, and give many positive and many qualified rights.

The inherent right in the people to reform their government, I do not deny; and they have another right, and that is to resist unconstitutional laws without overturning the government.
