 Today, philosophy of religion is one of the most vibrant areas of philosophy. Articles in philosophy of religion appear in virtually all the main philosophical journals, while some journals (such as the International Journal for Philosophy of Religion, Religious Studies, Sophia, Faith and Philosophy, and others) are dedicated especially to philosophy of religion. Philosophy of religion is in evidence at institutional meetings of philosophers (such as the meetings of the American Philosophical Association and of the Royal Society of Philosophy). There are societies dedicated to the field such as the Society for Philosophy of Religion (USA) and the British Society for Philosophy of Religion and the field is supported by multiple centers such as the Center for Philosophy of Religion at the University of Notre Dame, the Rutgers Center for Philosophy of Religion, the Centre for the Philosophy of Religion at Glasgow University, The John Hick Centre for Philosophy of Religion at the University of Birmingham, and other sites (such as the University of Roehampton and Nottingham University). Oxford University Press published in 2009 The History of Western Philosophy of Religion in five volumes involving over 100 contributors (Oppy &amp; Trakakis 2009), and the Wiley Blackwell Encyclopedia of Philosophy of Religion in five volumes, with over 350 contributors from around the world, is scheduled for publication by 2021. What accounts for this vibrancy? Consider four possible reasons.
