But other than Taylor, I recommend Robert Bellah's Religion in Human Evolution, William James' The Varieties of Religious Experience, and most books by Nietzsche, but specifically Beyond Good and Evil and The Genealogy of Morality. You might want to pick up an anthology of papers / topics, like Philosophy of Religion: An Anthology by Pojman. Max Weber and Durkheim are also considered to be foundational thinkers in religious sociology. If you get through all that and are looking for something a bit more obscure but super interesting, I would also check out "process philosophy" or "process theology", which addresses a lot of the traditional issues with religious arguments.
