Jonathan (Eds.), The Power of Religion in the Public Sphere (pp. 15-33). New York: Columbia University Press. (Habermas uses arguments, reasons, truth contents, language to represent religious ideas or experiences. For him, because religious experiences are particular and peculiar to their adherents they have to be translated into secular language, that is, language that has general accessibility that is understandable both to the religious and non religious citizens as well.)
