They don’t seem to always exist in perfect harmony. Yet, in the current post-secular society, religion and democracy can’t make it without each other. That applies to the Western world, where more faiths live together in the same territory and where we face a religious revival (even though religion, to be true, never disappeared). But it is also valid for Muslim societies, where Islam needs to bring modernity, autonomous reason and science to account. Between a democracy subjugated by the ideology of secularization and one dominated by faith, is there possibly a third way?
