My flagship defense of a naturalist worldview (and of philosophy in general), Sense and Goodness without God: A Defense of Metaphysical Naturalism, is now available as an audio book, through Audible.com. It’s a fairly faithful reading, so even things I’d probably change now (mostly minor stuff) is still in there (I didn’t want to deviate too much into creating a second edition just yet), but I still had to leave out many of the internal cross references and all the bibliographies.
To get those bibliographies in audio, you still have to get something like the kindle edition and run voice-to-text on them. They frequently appear at the end of each section, and there are a lot of them. So to make that task easier, I’ve compiled a single PDF file on my website (Bibliographies for the Original 2005 Edition) that just has the bibliographies, one after another, on which you can then run text-to-speech (so you don’t have to try and search the book for where the bibliographies are, a tedious task for the visually impaired).
Do note that those bibliographies are obviously ten years out of date (I completed the book in early 2004, and it was published in 2005), but I wanted to make speech-conversion available for the original edition of the book. Even if I were to update these bibliographies, I would usually just be adding the most recent best works. The ones in there now are still relevant to their respective topics and represent what I was working from at the time. And there are still a lot of crucial readings and good recommendations in there. I have found that leading works published after 2003 (which I have been keeping track of) almost always further confirm my conclusions, or provide better and more up-to-date explanations of why the facts I was relying on are correct.
