Ideologically speaking

Chapter intro in Steven Pinker's "The Better Angels of Our Nature:" 

Macbeth’s self-justifications were feeble—and his conscience devoured him. Yes, even Iago was a little lamb too. The imagination and the spiritual strength of Shakespeare’s evildoers stopped short at a dozen corpses. Because they had no ideology. — Aleksandr Solzhenitsyn

Oh, to fervently wish for a shortage of ideology in the USA. 

And, perhaps, a shortage of volume in Mr. Pinker's 1,009-page (digital) tome.
