The causes of this are not far to seek. Pericles indeed, by his rank, ability, and known integrity, was enabled to exercise an independent control over the multitude—in short, to lead them instead of being led by them; for as he never sought power by improper means, he was never compelled to flatter them, but, on the contrary, enjoyed so high an estimation that he could afford to anger them by contradiction.

Whenever he saw them unseasonably and insolently elated, he would with a word reduce them to alarm; on the other hand, if they fell victims to a panic, he could at once restore them to confidence. In short, what was nominally a democracy became in his hands government by the first citizen.
