  Symons and Alvarado (2019) argue that there is a fundamental problem with this approach to EOCS and it has to do with a feature of computer-aided proof that was crucial to Burge’s original account: that of a being a ‘transparent conveyor’. “It is very important to note, for example, that Burge’s account of content preservation and transparent conveying requires that the recipient already has reason not to doubt the source” (p. 13). But Symons and Alvarado point to many of the properties of computer simulations (drawing from Winsberg 2010 and Ruphy 2015) in virtue of which they fail to have these properties. Lenhard and Küster 2019 is also relevant here, as they argue that there are many features of computer simulation that make them difficult to reproduce and that therefore undermine some of the stability that would be required for them to be transparent conveyors. For these reasons and others having to do with many of the features discussed in 4.2 and 4.3, Symons and Alvarado argue that it is implausible that we should view computer simulation as a basic epistemic practice on a par with sense perception, memory, testimony, or the like.
