David Deutsch Books Unendorsement

I thought that even though David Deutsch (DD) and his fans were harassing me, his books were still good. But I hadn’t reread them for years. On review, The Beginning of Infinity contains lots of misquotes. DD’s books are a lot worse than I realized. I was horrified to discover how frequently and severely DD misquotes. I trusted DD’s ability to quote accurately and handle details reliably and correctly, but I was wrong.

Also, DD explains too little in his books. They’re too hard to learn effectively from because he doesn’t give enough depth or detail. I had trouble seeing this in the past because I had many conversations with DD which filled in the gaps for me. But even when DD’s books say something important, he often doesn’t provide enough information for a reasonable, smart person to understand it well.

DD’s books have some good parts mixed in, but, due to the serious flaws, I retract my recommendation of them. I no longer want to actively promote them.

I’m sorry. I should have caught the misquotes earlier. I was capable of finding those errors years ago. I found and wrote about other similar errors.

I was giving DD space after he left the community. I guessed (I think accurately) that he wanted to be left alone by me and I was trying to respect his wishes. I mostly stayed away from him and his work after he left. I thought continuing to recommend his books was safe, but I was wrong about that.

I only started my video series about BoI after I gave up on DD leaving me alone. I caught the Feynman misquote in chapter 1 when I first reread it for the videos. BoI misquotes Feynman:

As the physicist Richard Feynman said, ‘Science is what we have learned about how to keep from fooling ourselves.’

Then, due to the harassment, I was reviewing old information and found a Popper misquote on an old TCS webpage. Someone (“Dec”) saw my post and told me that the same Popper quote was in BoI too. That made two misquotes in BoI, which was a possible pattern. That led to checking more quotes, which led to discovering that there are tons misquotes in BoI.

It seems that no other readers of BoI have noticed the misquoting problem yet (the errata page has factual errors but no misquotes), which I think is important information about the world. Regardless, I should have done better.

Read about the misquotes.
