It is the belief that if one knows something, and knows what that entails, then can conclude that can be certain. The argument entails through plausible steps. The first step supports that in order to know that a hypotheses is true based on evidence that can rule out alternative possibilities. The second step states that there are numerous possibilities that are unreliable with what one claims to know about the external world. The third step asserts that the evidence does not necessarily rule the possibilities out (Greco, 2007).
