Such variations in the scale of national energy pervade history, modern as well as ancient, but in regard to Grecian history, especially, they can never be overlooked. For a certain measure, not only of positive political attachment, but also of active self-devotion, military readiness, and personal effort, was the indispensable condition of maintaining Hellenic autonomy, either in Athens or elsewhere; and became so more than ever when the Macedonians were once organized under an enterprising and semi-Hellenized prince. The democracy was the first creative cause of that astonishing personal and many-sided energy which marked the Athenian character, for a century downward from Kleisthenês. That the same ultra-Hellenic activity did not longer continue, is referable to other causes, which will be hereafter in part explained. No system of government, even supposing it to be very much better and more faultless than the Athenian democracy, can ever pretend to accomplish its legitimate end apart from the personal character of the people, or to supersede the necessity of individual virtue and vigor. During the half-century immediately preceding the battle of Chæroneia, the Athenians had lost that remarkable energy which distinguished them during the first century of their democracy, and had fallen much more nearly to a level with the other Greeks, in common with whom they were obliged to yield to the pressure of a foreign enemy. I here briefly notice their last period of languor, in contrast with the first burst of democratical fervor under Kleisthenês, now opening,—a feeling which will be found, as we proceed, to continue for a longer period than could have been reasonably anticipated, but which was too high-strung to become a perpetual and inherent attribute of any community. CHAPTER XXXII. RISE OF THE PERSIAN EMPIRE. — CYRUS. In the preceding chapter, I have followed the history of Central Greece very nearly down to the point at which the history of the Asiatic Greeks becomes blended with it, and after which the two streams begin to flow to a great degree in the same channel. I now revert to the affairs of the Asiatic Greeks, and of the Asiatic kings as connected with them, at the point in which they were left in my seventeenth chapter.
