 However, (a) – (d) are incomplete in a way directly relevant to the present discussion. Here is a very simple case. Suppose that an elderly uncle dies in suspicious circumstances, and a number of the relatives believe that the correct explanation is the direct agency of a niece who is primary heir, via deliberately and directly administering poison. However, forensic investigation establishes that the cause of death was a mix-up among medications the uncle was taking—an unfortunate confusion. The suspicious relatives, however, without missing an explanatory beat shift the niece’s agency back one level, proposing that the mix-up itself was orchestrated by the niece—switching contents of prescription bottles, no doubt. And that might very well turn out to be the truth.
