I've spent a considerable amount of time researching and trying to wrap my head around the concept of existentialism.  I've made this podcast in order to sort of recap a few of the highlights I've run across in my own thinking on the subject.  Along with the idea of infinite regression, it's a foundational concept into some other topics I intend to explore with anyone interested in learning these ideas, and I hope that it may be of some use to someone, as it has been for me.  Enjoy!
