Really, do you know anything about the founding of the American republic or the political thought of the American founders or where they came up with the ideas of divided government or drew their philosophical inspiration? Have you ever bothered to pick up the Tusculan Disputations or any of Cicero's letters or any of his writings on political philosophy?
In early American history, Cicero was more widely read and more influential than any other political thinker, including perhaps John Locke. Jefferson was a tremendous admirer of Cicero, modelling his life on Cicero's, and he considered the jewels of his immense library to be the 40 volumes of Cicero that he later donated to the Library of Congress. James Madison cites "Tully" with more reverence than Jesus. According to John Adams, "All ages of the world have not produced a greater statesman and philosopher combined." Cicero was not only required reading at Harvard and every university in early America, being able to recite Cicero in Latin was a minimum requirement for entry.
To say that Cicero's ideals have no bearing on modern republics is a statement of ignorance so vast... well, respect for this forum prevents me from saying anything more to you on this topc. Your chronic and willful indifference to historical facts make conversation with you pointless.
Cicero didn't make the Roman republic, which is used as a model in modern republics today. As for people admiring him, although I find it revolting to admire such a person of emmense hypocrisy, admiring him is not enough to credit him as a model for modern republics, if you are going to use that logic Cato, then you would have to credit Caesar with modern militaries, tactics, startegies, achievements and warfare, in that case though Caesar contributed much so he deserves the credit.
Cato it's not historical facts, it's your selective memory. Cicero's long lasting achievements for the Roman empire were his oratory, his political ideals didn't go anywhere.
Put aside your Strawman. The argument has nothing to do with who invented the republic, but whether or not Ciceros arguments and writings influenced the development of modern republican governments.
Admiring him not enough to credit him as an influence? If the admiration was idle or academic, yes, but Cato has already provided several examples of framers whose political thought was molded in part by his. Your analogy to Caesar is flawed because it is based on the ideas, refuted above, that Cicero is being established as the primary founding character and that this claim is backed by idle or whistful admiration as opposed to actual intellectual influence.
If then we have established that Cicero and his ideas were an influence on the American founders, and thereby on the founders of later republics as well, we can safely agree that his ideals have moved along to a very great somewhere indeed.
