 Given the above, broad perspective of what counts as religion, the roots of what we call philosophy of religion stretch back to the earliest forms of philosophy. From the outset, philosophers in Asia, the Near and Middle East, North Africa, and Europe reflected on the gods or God, duties to the divine, the origin and nature of the cosmos, an afterlife, the nature of happiness and obligations, whether there are sacred duties to family or rulers, and so on. As with each of what would come to be considered sub-fields of philosophy today (like philosophy of science, philosophy of art), philosophers in the Ancient world addressed religiously significant themes (just as they took up reflections on what we call science and art) in the course of their overall practice of philosophy. While from time to time in the Medieval era, some Jewish, Christian, and Islamic philosophers sought to demarcate philosophy from theology or religion, the evident role of philosophy of religion as a distinct field of philosophy does not seem apparent until the mid-twentieth century. A case can be made, however, that there is some hint of the emergence of philosophy of religion in the seventeenth century philosophical movement Cambridge Platonism. Ralph Cudworth (1617–1688), Henry More (1614–1687), and other members of this movement were the first philosophers to practice philosophy in English; they introduced in English many of the terms that are frequently employed in philosophy of religion today, including the term “philosophy of religion”, as well as “theism”, “consciousness”,and “materialism”. The Cambridge Platonists provided the first English versions of the cosmological, ontological, and teleological arguments, reflections on the relationship of faith and reason, and the case for tolerating different religions. While the Cambridge Platonists might have been the first explicit philosophers of religion, for the most part, their contemporaries and successors addressed religion as part of their overall work. There is reason, therefore, to believe that philosophy of religion only gradually emerged as a distinct sub-field of philosophy in the mid-twentieth century.
