  Given the thesis that evidence is that which justifies belief, one's intuitions about the evidence that is available to an individual in a hypothetical scenario will shape one's views about what the individual would be justified in believing in that scenario. Of course, one can also theorize in the opposite direction as well: to the extent that one has independent intuitions about what an individual would be justified in believing in a given scenario, such intuitions will shape one's views about what evidence must be available to an individual so situated—and therefore, one's views about the more general theoretical issue about what evidence is, or what sorts of things can and cannot qualify as evidence. Thus, if one is firmly convinced that an individual in circumstances C might be justified in believing that p is the case, it follows immediately that being in circumstances of kind C is consistent with having evidence sufficient to justify the belief that p. As we will see below (Section 2), reasoning of this general form has often encouraged a picture according to which one's total evidence is exhausted by one's present experiences.
