Medieval philosophy
The term "philosophy of religion" did not come into general use in the West until the nineteenth century, and most pre-modern and early modern philosophical works included a mixture of religious themes and non-religious philosophical questions. In Asia, examples include texts such as the Hindu Upanishads, the works of Daoism and Confucianism and Buddhist texts. Greek philosophies like Pythagoreanism and Stoicism included religious elements and theories about deities, and Medieval philosophy was strongly influenced by the big three monotheistic Abrahamic religions. In the Western world, early modern philosophers such as Thomas Hobbes, John Locke, and George Berkeley discussed religious topics alongside secular philosophical issues as well.
