Hello,

Here are some sites which provide sermons, talks, lectures and free downloadable audiobooks on Religion and philosophy:

All SSPX stuff you  desire!

http://librivox.org

- scroll through the catalog to find St. Augustine, St. Bernard of Clairvaux and more.

http://catholicaudio.blogspot.com

- a treasure trove of catholic audiofiles. I highly recommend the talks by Michael Davies and Dr. Wm. A. Marra. A fair warning: the blogger has refused to post SSPX audio files and some of the featured speakers are of the "councilliar" persuasion.

Here you can find Plato's Apology and The Republic and Cicero's Treatise on Friendship
