 Nonetheless, Lewis (1952a, reprinted in Lewis 1970, 326) says “the validity of this interpretation is that and that only which could attach to it as an inductive inference from the given visual presentation...the incorrigible presentational element”. What matters for the credibility or warrant or validity of the belief is that there is a logical, inferential relation between the belief and grounds in experience that prompt it in the light of past experience and that can be elicited on critical reflection and the character of the relation made clear enough for our theoretical purposes. However, the credibility or validity of the belief isn’t created by the reflective attempt to elicit sufficient grounds (Lewis 1946, 186, 189, 262, 329–32) The given, thus, plays both a causal role as the ultimate or remote ground responsible for belief and an epistemic role as the ultimate justifying grounds of empirical belief. (Lewis 1946, 262, 328–30).
