Forgive my tardiness in responding,Foolestroupe,I was helping Russell & Wittgenstein remove a recalcitrant Rhino from their rooms.
Having done that I went to wash my hands but the sink had both a hot and a cold tap and ,consequently, disappeared in a puff of logic.
You are right that circular logic only makes people dizzy though.
"Wovon man nicht sprechen kann,darueber muss man schweigen."
As a former porter of one of my local hospitals was wont to say.
Good response Greg.
