I have put two copies of the lectures on religion, (MP3 Version, or DSS version) on sports, (MP3 version, or DSS version) and on work (MP3 version or DSS version) onto the program web page.

The MP3 files are very large. In fact they are too large to use at the moment. So please use the DSS files.
So, if you think you have a long term interest in audio files, do download DSS to your home computer.

To hear the DSS version you may need to download the DSS software for free using this link.
 
To hear the MP3 version you can try your own computer's audio software. It can almost certainly play an MP3 file.
