Discourses on Livy

That to preserve a newly acquired freedom we must slay the sons of Brutus.

The severity used by Brutus in preserving for Rome the freedom he had won for her, was not less necessary than useful. The spectacle of a father sitting on the judgment, and not merely sentencing his own sons to death, but being himself present at their execution, affords an example rare in history. But those who study the records of ancient times will understand, that after a change in the form of a government, whether it be from a commonwealth to a tyranny or from a tyranny to a commonwealth, those who are hostile to the new order of things must always be visited with signal punishment. So that he who sets up as a tyrant and slays not Brutus, and he who creates a free government and slays not the sons of Brutus, can never maintain himself long. But since I have elsewhere treated of this matter at large, I shall merely refer to what has there been said concerning it, and shall cite here one instance only, happening in our own days, and memorable in the history of our country.
