"You are all eyes for speeches, all ears for deeds; you judge of the possibility of a project from good speeches; accomplished facts you believe not because you see them but because you hear them from smart critics. You are easily duped by some novel plan, but you refuse to adhere to what has been proved sound. You are slaves to every new oddity and have nothing but contempt for what is familiar. Every one of you would like to be a good speaker, failing that, to rival your orators in cleverness. You are as quick to guess what is coming in a speech as you are slow at foreseeing its consequences. In a word, you live in some non-real world." He pleaded for the rigorous application of the extreme penalty already voted. He was opposed by Diodotus, who appealed to the same principle as Cleon did expediency. "No penalty will deter men, not even the death penalty. Men have run through the whole catalogue of deterrents in the hope of securing themselves against outrage, yet offences still are common. Human nature is driven by some uncontrollable master passion which tempts it to danger. Hope and Desire are everywhere and are most mischievous, for they are invisible. Fortune too is as powerful a means of exciting men. At tunes she stands unexpectedly at their side and leads them to take risks with too slender resources. Most of all she tempts cities, for they are contending for the greatest prizes, liberty or domination. It is absolutely childish then to imagine that when human nature is bent on performing a thing it will be deterred by law or any other force. If revolting cities are quite sure that no mercy will be shown, they will fight to the last, bequeathing the victors only smoking ruins. It would be more expedient to be merciful and thus save the expenses of a long siege."
