Is the Master's Discourse Repressed?

Lacan: The truth of the master cannot be avowed. If you're going to be a master, you can't avow you're a barred subject. So it's interesting that he says even mastery is blind to fantasy. That's part of what he's getting at with that laying out the structure of the one on top and the other on the bottom. And I think despite Lacan avowing, I forget the page on this where he says he's not a man of the left.
