“This essential principle of our Constitutional Republic is being ridden roughshod over by imperial Washington, which bullies local governments into accepting its illegal and unconstitutional policies.”

On New Democracy (1940)
Original: (zh-CN) 国体——各革命阶级联合专政。政体——民主集中制。这就是新民主主义的政治，这就是新民主主义的共和国，这就是抗日统一战线的共和国，这就是三大政策的新三民主义的共和国，这就是名副其实的中华民国。我们现在虽有中华民国之名，尚无中华民国之实，循名责实，这就是今天的工作。

I confess I secretly suspect the Republicanism of an orator who is more anxious to show his hearers that he respects what he calls the rights of slavery than that he loves the rights of man. If God be just and the human instinct true, slavery has no rights at all. It has only a legalized toleration. Have I a right to catch a weaker man than I, and appropriate him, his industry, and his family, forever, against his will, to my service? Because if I have, any man stronger than I has the same right over me. But if I have not, what possible right is represented by the two thousand million dollars of property in human beings in this country? It is the right of Captain Kidd on the sea, of Dick Turpin on the land. I certainly do not say that every slave-holder is a bad man, because I know the contrary. The complicity of many with the system is inherited, and often unwilling. But to rob a man of his liberty, to make him so far as possible a brute and a thing, is not less a crime against human nature because it is organized into a hereditary system of frightful proportions. A wrong does not become a right by being vested.

1970s, First Presidential address (1974)
Context: My fellow Americans, our long national nightmare is over.
Our Constitution works; our great Republic is a government of laws and not of men. Here the people rule. But there is a higher Power, by whatever name we honor Him, who ordains not only righteousness but love, not only justice but mercy.
As we bind up the internal wounds of Watergate, more painful and more poisonous than those of foreign wars, let us restore the golden rule to our political process, and let brotherly love purge our hearts of suspicion and of hate.

Essay in the American Daily Advertiser (28 August 1794)

As quoted in The Washington Post (23 December 1973); he later joked further on this remark, on 10 March 1975 saying to Turkish Foreign Minister Melih Esenbel in Ankara, Turkey:
Before the Freedom of Information Act, I used to say at meetings "The illegal we do immediately. The unconstitutional takes a little longer." … But since the Freedom of Information Act, I'm afraid to say things like that.
