I first read many PG's essays, and only recently has seen him on video. But, by that time, my attitude was set in such way, that I take his ummms as a sign that he is taking a wee bit of time to translate what is going in his head into more human understandable form. His essays show clearly the depth of thinking. Such thoughts need extra effort/time to translate from human lisp to human language. So, I have no problem that PG takes a second now and then to formulate a thought to be understandable by a wider audience.
