Here:
To begin with, the idea that “existence exists” excludes the idea that existence doesn’t exist. It denies the subjectivist, pragmatist, postmodernist view that reality is an illusion, a mental construct, a social convention. Obviously, people who insist that reality is not real are not going to buy in to a philosophy that says it is real.
So that’s one huge problem with Rand’s philosophy.
Now I am no fan of Ayn Rand: my Rand category is chock-full of trenchant criticisms of her and her acolytes. But the above is so stupid as to be beyond belief.
Forgive me for stating the obvious. One cannot refute a view by pointing out that there are those who do not accept it.

This just in from Patrick Toner:
Off to class in two minutes, but I thought I should send a quick note to say that I think Biddle's piece is satirical. Or something like that. It wasn't meant as a refutation. I hope you're well!
Professor Toner may well be right. You decide.
