Agis and Cleomenes (Agis.2.3-Agis.2.4)

Ye cannot have the same man as your ruler and your slave. Since in this case also one certainly can apply the fable of the serpent whose tail rebelled against its head and demanded the right to lead in turn instead of always following; so it took the lead, and by the folly of its progress got itself into mischief and lacerated the head, which was compelled, contrary to nature, to follow a part that had neither eyes nor ears.

This, as we see, has been the experience of many of the men whose whole political activity is directed towards the winning of popular favour; they made themselves dependent on the multitude, which is borne about at random, and then could neither recover themselves nor put a stop to the progress of disorder.

These remarks upon the glory which comes from the favour of the multitude I have been led to make because I was reminded of its great influence by the fortunes of Tiberius and Caius Gracchus. They were men of most generous natures, and had a most generous rearing, and adopted most generous political principles; and yet they were ruined, I will not say by an immoderate desire for glory, but rather by a fear of losing it. And this fear had no unworthy origin.
