As Grecian history has been usually written, we are instructed to believe that the misfortunes, and the corruption, and the degradation of the democratical states are brought upon them by the class of demagogues, of whom Kleon, Hyperbolus, Androklês, etc., stand forth as specimens. These men are represented as mischief-makers and revilers, accusing without just cause, and converting innocence into treason. Now the history of this conspiracy of the Four Hundred presents to us the other side of the picture. It shows that the political enemies—against whom the Athenian people were protected by their democratical institutions, and by the demagogues as living organs of those institutions—were not fictitious but dangerously real. It reveals the continued existence of powerful anti-popular combinations, ready to come together for treasonable purposes when the moment appeared safe and tempting. It manifests the character and morality of the leaders, to whom the direction of the anti-popular force naturally fell. It proves that these leaders, men of uncommon ability, required nothing more than the extinction or silence of the demagogues, to be enabled to subvert the popular securities and get possession of the government. We need no better proof to teach us what was the real function and intrinsic necessity of these demagogues in the Athenian system, taking them as a class, and apart from the manner in which individuals among them may have performed their duty. They formed the vital movement of all that was tutelary and public-spirited in democracy. Aggressive in respect to official delinquents, they were defensive in respect to the public and the constitution. If that anti-popular force, which Antiphon found ready-made, had not been efficient, at a much earlier moment, in stifling the democracy, it was because there were demagogues to cry aloud, as well as assemblies to hear and sustain them. If Antiphon’s conspiracy was successful, it was because he knew where to aim his blows, so as to strike down the real enemies of the oligarchy and the real defenders of the people. I here employ the term demagogues because it is that commonly used by those who denounce the class of men here under review: the proper neutral phrase, laying aside odious associations, would be to call them popular speakers, or opposition speakers. But, by whatever name they may be called, it is impossible rightly to conceive their position in Athens, without looking at them in contrast and antithesis with those anti-popular forces against which they formed the indispensable barrier, and which come forth into such manifest and melancholy working under the organizing hands of Antiphon and Phrynichus.
