Well, I guess you will have to devote your life to study and become one of the: Peddlers of Lacan
.(A bad place for a Settlers of Catan reference?)
I don't have the patience to devote myself to outmoded linguistics just to figure out what Lacan was talking about(which is probably the psychoanalysis of desire). If he wants to use the logical structure of mathematical terms to explain how he views the logical structure of the human mind, fine, even if he's being tongue and cheek. I just wouldn't spend my time pursuing it as I have little interest.
So far this looks like a trolling thread. Thats fine, but it will get deleted.
In the meantime, if you had anything else you wanted to discuss, I'm bored so I'll probably chime in.
