 The starting point of Lehrer’s account of coherence is the fact that we can think of all sorts of objections an imaginative critic may raise to what a person accepts. These objections might be directly incompatible with what that person accepts or they might threaten to undermine her reliability in making assessments of the kind in question. For instance, a critic might object to her claim that she sees a tree by suggesting that she is merely hallucinating. That would be an example of the first sort of objection. An example of the second sort would be a case in which the critic replies that the person cannot tell whether she is hallucinating or not. Coherence, and (personal) justification, results when all objections have been met.
