To evoke another great phrase of the American revolutionary heritage — widely though inconclusively attributed to Thomas Jefferson — the price of liberty is eternal vigilance. Such a phrase is merely trite, however, unless we consider its deeper implications. For the French revolutionaries, as for so many regimes that have succeeded them across the world up to the present day, the call for vigilance against enemies, both external and internal, was the first step on the road to the loss of liberty, and lives.Of far more significance, and the true and tragic lesson of the epic descent into The Terror, is the summons to vigilance against ourselves — that we should not assume that we are righteous, and our enemies evil; that we can see clearly, and to others are blinded by malice or folly; that we can abrogate the fragile rights of others in the name of our own certainty and all will be well regardless.If we do not honor the message of human rights born in the revolutions of 1776 and 1786, as the French in their case most certainly failed to do, we too are on the road to The Terror.

The revolutionary Terror, which is attacked for its revolutionary tribunal, its law of suspects and its guillotine, was a process welded to a regime of popular sovereignty in which the object was to conquer tyranny or die for liberty. This Terror was willed by those who, having won sovereign power by dint of insurrection, refused to let this be destroyed by counter-revolutionary enemies
