Donald Trump has internalized the maxim Benjamin Jowett gave to his students at Balliol who would soon be running the empire.

And in rejecting demands that he apologize for his remarks about the La Raza judge presiding over the class-action suit against Trump University, the Donald is instinctively correct

Assume, as we must, that Trump believes what he said.

Why, then, should he apologize for speaking the truth, as he sees it?

To do so would be to submit to extortion, to recant, to confess to a sin he does not believe he committed. It would be to capitulate to pressure, to tell a lie to stop the beating, to grovel before the Inquisition of Political Correctness.

Trump is cheered today because he defies the commands of political correctness, and, to the astonishment of enemies and admirers alike, he gets away with it.

To the establishment, Trump is thus a far greater menace than Bernie Sanders, who simply wants to push his soak-the-rich party a little further in the direction of Robin Hood and his Merry Men.

But Trump, with his defiant refusal to apologize for remarks about "rapists" among illegal immigrants from Mexico, and banning Muslims, is doing something far more significant.

He is hurling his "Non serviam!" in the face of the establishment. He is declaring: "I reject your moral authority. You have no right to sit in judgment of me. I will defy any moral sanction you impose, and get away with it. And my people will stand by me."

Trump's rebellion is not only against the Republican elite but against the establishment's claim to define what is right and wrong, true and false, acceptable and unacceptable, in this republic.

Contrast Trump with Paul Ryan, who has buckled pathetically.
