Satish Kumar was one of those I interviewed for my Channel 4 documentary, ‘Enemies of Reason.’ He began by telling a nice story about Bertrand Russell, whom he met as a young man and who supported him. We moved on to holism, which seemed harmless enough, but as the interview wore on, he became more and more mystical, culminating in the treeness of trees, I couldn't help wondering what Bertrand Russell would have said.
