Intellectuals say we can infer things from unexplained coincidences indirectly. Suppose you check into a hotel, are assigned room 1960 and note that this is the year you were born. What a coincidence you say. After a moment of reflection, however, you conclude that this is not so surprising at all. The hotel has hundreds of rooms, and you would not have these thoughts in the first place if you had been assigned one with a number that meant nothing to you. Even if you knew nothing about hotels, you could infer the existence of other hotel rooms to explain the coincidence.
