Same. I emailed him about whether he'd ever met Margaret Mead, John C. Lilly, or Gregory Bateson in the 1960s while researching my book. I got this reply within hours:
"Afraid I never met any of those you mention, though I’ve followed their work for many years.
I’ve never been close to intellectual elite circles, including people I very much admire."
