||While the philosophy of religion in the west dates back to the works of Plato (e.g,. Plato 1977) and Aristotle (Aristotle 2007), it was in the medieval period that interest in religious matters became central in the work of philosophers. Augustine 2006, Aquinas 1274, and Anselm 1979 are classics from that period.The classic from the modern area is Gaskin 1998/2009. In the latter half of the twentieth century, the philosophy of religion came out of hibernation. Flew et al 1964 is a collection in which religious language is considered in light of the verificationism that was rampant at the time. Among the key works published in the final quarter of the century were Hick 1966, Plantinga 1992, Swinburne 1993, Mackie 1982, and Alston 1991.
