History of the Peloponnesian War

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.

With his successors it was different. More on a level with one another, and each grasping at supremacy, they ended by committing even the conduct of state affairs to the whims of the multitude.

This, as might have been expected in a great and sovereign state, produced a host of blunders, and amongst them the Sicilian expedition; though this failed not so much through a miscalculation of the power of those against whom it was sent, as through a fault in the senders in not taking the best measures afterwards to assist those who had gone out, but choosing rather to occupy themselves with private cabals for the leadership of the commons, by which they not only paralyzed operations in the field, but also first introduced civil discord at home.
