Irreligiosophy means “the wisdom of irreligion” — it is about questioning dogmas handed down uncritically to us and researching into the history, practice, and theology of various religions. It’s about scrutinizing religious claims with a skeptical eye and placing them in historical perspective. But ultimately, Irreligiosophy 2.0 is really about arming atheists to wage the culture war with arguments and reason. We focus on Christianity because that is the religion that we are most confronted by in our daily lives, but we see all religion and all irrationality as threats to the continued advancement of knowledge, progress, and social justice.
