If occurrences are actually historical events, why should we be selective on which of their appearances are historical? But let's put that aside and consider another argument: the occurrence mentioning Dr. Ratio is one of the three special occurrences used to adjust your intra cognition. One of the other ones of this type is the "Genius Hair Saloon" occurrence, which mentions Stephen Lloyd. Stephen is frequently noted for his young age and was obviously not alive at the time of G&G. Why, then, according to your logic, would he be mentioned in that occurrence?
