  The earliest major approach in the contemporary literature to bringing cognitive limits to bear upon the argument from evil is the epistemic principles approach, inaugurated by Wykstra (1984, but see also Alston 1996/1991, 122, n11 in Howard-Snyder 1996b). He has continued to defend and expand this strategy to the present day (Russell and Wykstra 1988, Wykstra 1996, 2007, 2009, and Wykstra and Perrine 2012 and forthcoming). Howard-Snyder 2009 makes a similar but more detailed reply based on a similar but importantly different epistemic principle. Plantinga (1988) also touches on the topic. (Some of what follows follows Dougherty 2011c.)
