> His great transgression, according to Berlin, was to say aloud what everyone knows but no one will admit: multiple ideals cannot be simultaneously attained. We can’t have everything good all at once.

Everyone will admit this. No one honestly believes all virtues are equally and simultaneously attainable. At any given time, certain things must be prioritized.

But some of us believe that it's not a zero-sum game; that "human nature" is not set in stone, and that it is a worthy project to try and engineer conditions which allow more of humanity's virtues to flourish. Machiavelli would seem to dismiss the possibility that a society can reorient itself towards empathy, charity, and equality without imploding. He also seems to believe that it's correct to trade individual prosperity for state power and glory.
