I’d say that $22 for a course–Leonard Peikoff’s 24-lecture set on the history of philosophy–which used to cost hundreds to purchase–is a pretty good deal. At its new Ayn Rand Institute eStore, the Ayn Rand Institute is selling for a song that course and many other courses and individual lectures in the format of downloadable MP3 files. I also downloaded Peikoff’s 1976 course on Objectivism, which includes Ayn Rand answering some of the questions in later lectures.
I’m not sure why these files are being offered so inexpensively, since the demand would be there for somewhat higher prices still a lot lower than the old prices for cassettes or CD-ROMs. These MP3 prices are much better than even The Teaching Company’s frequent cut-rate sale prices for courses. Now would be the time to download from the ARI eStore any sets or individual lectures you are interested in, as for sure the prices are not going to go lower.
