The sequence "A Human's Guide to Words" is now available as a professionally read podcast.
We have started working on the large "Reductionism" sequence which includes both the "Joy in the Merely Real" and the "Zombies" sub-sequences. They should be available in a couple of weeks.
As someone who is arguably better at auditory processing vs. visual I much up vote this effort. I bought both available podcasts and the quality is good. Intend to buy others as they become available.
