I don"t know that i am seeing a barn, because i may not properly ignore the possibility that i am seeing yet another of the abundant bogus barns. Permissive rules: rule of reliability: captures what is right about causal or reliabilist theories of knowing. Consider processes whereby information is transmitted to us: perception, memory, and testimony. Of course, it is possible to hallucinate - even to hallucinate in such a way that all my perceptual experience and memory would be just as they actually are.

We can ignore these possibilities to to be flat.
