"I don't know much about Lisp beyond SICP, and if I claimed I did you would have no way of knowing whether or not I'm telling the truth."
Well, someone as good as or better than you could tell if you're telling the truth. Of course, unless he himself wanted to know if it's the truth then someone as good as or better than himself would have to validate his validation of your claims. So it's a recursive chain-of-trust problem thing.
PG is not exactly the last word on lisp, for example I think a good implementation of Common Lisp knows more about it than he does ;P
