Sam Harris is one of America's leading atheists, and he hosts a very popular podcast called Waking Up. I almost always find his interviews interesting. Two recent episodes are especially exceptional. Naturally the titles will tell you something about the subject matter of each, but do yourself a favor and surprise yourself. Just click and start listening. You will be glad you did.
Here is a conversation between two avid historians that interested me greatly. Note especially their struggle with judging cultural norms and practices in history.
One of the better discussions on Unbelievable. James White converses with Roman Catholic apologist, Peter D Williams. The level of transparency and degree of communication is what makes this conversation so good.
If you haven't heard Joe Boot before, give this episode a listen. I just love his clear, strong Christian voice on matters cultural.
