One must consider that Alan Watts himself was a magnificent old rascal. He made no pretense about it and described himself as a “philosophical entertainer”. When you verify his teachings (either by experience or by going to the source) you find a lot of deliberate bending. His interpretation of the Tao Te Ching is deeply idiosyncratic, for example. Though I suspect there’s some degree of truth in his opinion of Gurdjieff, I wouldn’t take his word for it.
