Against Aristogeiton I

Let me put it in this way. Perhaps none of you has ever been bitten by an adder or a tarantula, and I hope he never may be. All the same, whenever you see such creatures, you promptly kill them all. In just the same way, men of Athens, whenever you see a false accuser, a man with the venom of a viper in his nature, do not wait for him to bite one of you, but always let the man who comes across him exact punishment.
