We do indeed know that Pete is alive. But the state of existence is not the same as the state of being alive. Any French philosopher can confirm this contention. Which leads me to ask the rhetorical question "are we certain it's Pete who made this posting". The person who made the posting has made a crucial error... he or she has spelt his pseudonym incorrectly. "Scen"? You have to be kidding. It's "Sven". This shows that the writer is an imposter. An imposter pretending to be Pete pretending to disown the writer of a Nigerian pretending to be Pete who wrote the original email. I rest my case.
