It is on this account that the discussions of savage tribes have produced so little effect in emancipating those tribes from their despotic customs. The oratory of the North American Indian--the first savage whose peculiarities fixed themselves in the public imagination--has become celebrated, and yet the North American Indians were scarcely, if at all, better orators than many other savages. Almost all of the savages who have melted away before the Englishman were better speakers than he is. But the oratory of the savages has led to nothing, and was likely to lead to nothing. It is a discussion not of principles, but of undertakings; its topics are whether expedition A will answer, and should be undertaken; whether expedition B will not answer, and should not be undertaken; whether village A is the best village to plunder, or whether village B is a better. Such discussions augment the vigour of language, encourage a debating facility, and develop those gifts of demeanour and of gesture which excite the confidence of the hearers. But they do not excite the speculative intellect, do not lead men to argue speculative doctrines, or to question ancient principles. They, in some material respects, improve the sheep within the fold; but they do not help them or incline them to leap out of the fold. The next question, therefore, is, Why did discussions in some cases relate to prolific ideas, and why did discussions in other cases relate only to isolated transactions? The reply which history suggests is very clear and very remarkable. Some races of men at our earliest knowledge of them have already acquired the basis of a free constitution; they have already the rudiments of a complex polity--a monarch, a senate, and a general meeting of citizens. The Greeks were one of those races, and it happened, as was natural, that there was in process of time a struggle, the earliest that we know of, between the aristocratical party, originally represented by the senate, and the popular party, represented by the 'general meeting.' This is plainly a question of principle, and its being so has led to its history being written more than two thousand years afterwards in a very remarkable manner. Some seventy years ago an English country gentleman named Mitford, who, like so many of his age, had been terrified into aristocratic opinions by the first French Revolution, suddenly found that the history of the Peloponnesian War was the reflex of his own time. He took up his Thucydides, and there he saw, as in a mirror, the progress and the struggles of his age. It required some freshness of mind to see this; at least, it had been hidden for many centuries. All the modern histories of Greece before Mitford had but the vaguest idea of it; and not being a man of supreme originality, he would doubtless have had very little idea of it either, except that the analogy of what he saw helped him by a telling object-lesson to the understanding of what he read.
