Hello,

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

http://traditionalcatholicmedia.com

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.

http://www.ejunto.com

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

If you happen to use iTunes there's a Catholic, and I do mean Catholic, College which provides free lectures and talks through iTunesU.

1. Download and install iTunes on your computer. 

2. Click on iTunes store

3. Once the store page comes up click "power search" on the right side of the window, type in "Christendom College" in the Title window and click search, look for the College link on the left side under "Institutions", click on the link and let the learning begin!
