Well, she did refer to Socrates, whom we know through his pupil Plato. There's no doubt that Plato thought a large part of a philosopher's job was to tell other people how to live - exhibit A is Plato's
Republicwhich just serendipitously happens to be run by philosophers, bans music, and is a thoroughly totalitarian document. As much as Plato is revered in some philosophical circles for the
Dialogues, he is reviled by many as both an idealist and a proto-totalitarian. The line from Plato to Rousseau, Hegel and Marx and his epigoni has been drawn many times by serious thinkers.
For myself, I found her article purile and rather pathetic, defending her person rather than her ideas, and trying hive everyone who disagrees with her off as some sort of Christian fundamentalist. 'Tain't so, and she ought to know better, but then she's lived in the Boston ivory tower for decades, the left-intellectual cocktail part circuit from Boston to Washington with detours to Martha's Vineyard and the Hamptons.
