At the Horizons of Modernity, by Canadian scholar Jarett Myskiw, argues that a theory of religion can be constructed upon a close reading of Jürgen Habermas' masterwork The Theory of Communicative Action (1984, 1987). While influential in many diverse fields of scholarly research, Habermas' thought has been relatively neglected in the academic study of religion, especially around the time of the above publication. At the Horizons of Modernity addresses this gap in research by considering Habermas' main arguments in terms of rationality, society, and communication, tying these to his engagements with the work of Max Weber and Émile Durkheim, then formulating a Habermasian theory of religion, before finally offering both a critique and suggestions for future research. A provocative and insightful critical treatment of Habermas' mature thought, At the Horizons of Modernity is certain to provoke sustained academic discussion and debate.
