Is "rational spirituality" a contradiction? In this episode, Massimo and Julia try to pin down what people mean when they call themselves "spiritual," what inspires spiritual experiences and attitudes, and whether spirituality can be compatible with a naturalist view of the world. Are there benefits that skeptics and other secular people could possibly get from incorporating some variants on traditional spiritual practices -- like prayer, ritual, song, communal worship, and so on -- into their own lives? Massimo and Julia examine a variety of attempts to do so, and ask: how well have such attempts worked, and do they come with any potential pitfalls for our rationality?
