(1) Refutation of the notion that Rand isn't popular, or "immortalized" in the minds of others
(2) Refutation of the notion that popularity entails significance

I erred in not mentioning Rand's reductio ad absurdum argument against a "sense-invalidity" one:

Therefore (using a method that can't be trusted), it follows that senses err.
