“It is unnecessary, for the Republic has never ceased to exist. I was the Republic.”

Address to the Colonization Society http://teachingamericanhistory.org/library/index.asp?document=562 (4 July 1829).
Context: I will say, finally, that I despair of the republic while slavery exists therein. If I look up to God for success, no smile of mercy or forgiveness dispels the gloom of futurity; if to our own resources, they are daily diminishing; if to all history, our destruction is not only possible, but almost certain. Why should we slumber at this momentous crisis? If our hearts were dead to every throb of humanity; if it were lawful to oppress, where power is ample; still, if we had any regard for our safety and happiness, we should strive to crush the Vampire which is feeding upon our life-blood. All the selfishness of our nature cries aloud for a better security. Our own vices are too strong for us, and keep us in perpetual alarm; how, in addition to these, shall we be able to contend successfully with millions of armed and desperate men, as we must eventually, if slavery do not cease?

Last Speech to the National Convention (26 July 1794)

The Socialist Party and the Working Class (1904)
Context: There has never been a free people, a civilized nation, a real republic on this earth. Human society has always consisted of masters and slaves, and the slaves have always been and are today, the foundation stones of the social fabric.
Wage-labor is but a name; wage-slavery is the fact.

Letter from Jamaica (Summer 1815)
Context: A state too expensive in itself, or by virtue of its dependencies, ultimately falls into decay; its free government is transformed into a tyranny; it disregards the principles which it should preserve, and finally degenerates into despotism. The distinguishing characteristic of small republics is stability: the character of large republics is mutability.
