I checked his website and it looks like another guy who got a degree in Far East philosophy. At this point in age, you will think people will know the difference of different transcriptions to render Chinese words. In his page What's cheng hsin you see that the Chinese characters are Chung hsin, then if you check the cheng hsin splash page then you see the correct Chinese character. I always wonder how much Chinese he learned and listening his interventions, it sounds like a book.
