 Many recent discussions of ontological arguments are in compendiums, companions, encyclopedias, and the like. So, for example, there are review discussions of ontological arguments in: Leftow 2005, Matthews 2005, Lowe 2007, Oppy 2007, and Maydole 2009. While the ambitions of these review discussions vary, many of them are designed to introduce neophytes to the arguments and their history. Given the current explosion of enthusiasm for compendiums, companions, encyclopedias, and the like, in philosophy of religion, it is likely that many more such discussions will appear in the immediate future.
