History of the Peloponnesian War

You seek, one might say, a world quite unlike that in which we live, but give too little heed to that which is at hand. In a word, you are in thrall to the pleasures of the ear and are more like men who sit as spectators at exhibitions of sophists than men who take counsel for the welfare of the state.

"And it is from these ways that I seek to turn you when I attempt to prove that Mytilene has done you more injury than any single state.

I can make allowance for men who resorted to revolt because they were unable to bear your rule or because they were compelled by your enemies to do so; but men who inhabited a fortified island and had no fear of our enemies except by sea, and even there were not without the protection of a force of their own triremes, who moreover were independent and were treated by us with the highest consideration, when these men have acted thus, what else is it but conspiracy and rebellion rather than revolt—for revolt is the work of those who suffer oppression—and a deliberate attempt by taking their stand on the side of our bitterest enemies to bring about our destruction? And yet this is assuredly a more heinous thing than if they had gone to war against us by themselves for the acquisition of power.

The calamities of their neighbours who had already revolted from us and been subdued proved no warning to them; nor did the good fortune which they enjoyed make them hesitate to take the perilous step; on the contrary, becoming over-confident as to the future, and conceiving hopes which, though greater than their powers, were less than their ambition, they took up arms, presuming to put might before right; for the moment they thought they should prove superior they attacked us unprovoked.
