The Madman's Narrative

Consider that two people can hold incompatible beliefs based on the exact same data. Does this mean that there are possible families of explanations and that each of these can be equally perfect and sound? Certainly not. One may have a million ways to explain things, but the true explanation is unique, whether or not it is within our reach.

In a famous argument, the logician WV Quine showed that there exist families of logically consistent interpretations and theories that can match a give series of facts. Such insight should warn us that mere absence of nonsense may not be sufficient to make something true.
