Good catch, Craig. Thanks. It looks like there is a backdoor into Objectivish thought for the Principle. I followed your link to a few places where it seems like the Principle transformed into Steelmanning. A meme on the move! And now lodged in the minds of the front porchers at Objectivist Living. It might be worth a split-off thread ... This is from a group blog, Less Wrong, which is said to be "devoted to refining the art of human rationality," in a 2011 article called Better Disagreement.
