Philosophie des Mittelalters
Medieval philosophy roughly extends from the Christianization of the Roman Empire until the Renaissance. It is defined partly by the rediscovery and further development of classical Greek and Hellenistic philosophy, and partly by the need to address theological problems and to integrate the then-widespread sacred doctrines of Abrahamic religion (Judaism, Christianity, and Islam) with secular learning. Some problems discussed throughout this period are the relation of faith to reason, the existence and unity of God, the object of theology and metaphysics, the problems of knowledge, of universals, and of individuation.
