A certain amount of paranoia seems healthy. I saw that line about
trusting people as possibly Pynchon suggesting to readers not to
invest belief in everything he says - in guerilla ontological fashion:
casting doubt about what to believe (trust) and what not to in the
grand conspiracy to get people to think for themselves rather than
automatically trusting the author will steer the reader right.
The comment about blurring his life and work reminds me of a similar
statement uttered by the Gertrude Stein character to Owen Wilson about
his writing and what she saw as the task of the Writer in the film
"Midnight In Paris." I can't repeat it verbatim but the film is worth
watching for that and much more. It's about a self-described
"Hollywood hack" played by Wilson trying to make it as a real writer,
his adventures with Time, and how he successfully does it.
