This book delves into Agamben claim that the experience of language, as it is manifested in the oath, precedes, and gives rise to religion, law and politics, and therefore should be seen as a crucial element of the human process. Arguing that Agamben's own language suffers from substantial and conceptual flaws and self-assertive opinions on language and the oath. The book considers the possibility of a new analytical methodology that could take on board multidisciplinary approaches into the study of religious ideologies and practices. Studying the role played by religion in society, and considering human beings as builder of symbolic worlds, it analyses the political readjustment of religion with respect to the rest of the social life.
