You must be on your guard against this and take care that nothing of the sort happens in this case and that you are not yourselves seen to fall into the very faults which you find reprehensible in others. I think you know well enough that time and again in the past Athens has so deeply repented1 the judgements which have been pronounced in passion and without proof that not long after the events she has become eager to punish her deceivers, and would gladly have seen the victims of calumny in happier circumstances than before.
1 The outstanding instance is the decree passed by the General Assembly, condemning to death without due process of law, the Athenian generals who were in command at the battle of Arginusae. After the execution of the sentence, the people repented of their haste and called to account the leading instigators of this irregular procedure. See Xen. Hell. 1.7.35; Plat. Apol. 32; Grote, History vol. vii. pp. 446-447.
