[W]e addressed the factual question whether members of the Trump Campaign “coordinat[ed]”-a term that appears in the appointment order-with Russian election interference activities. Like collusion, “coordination” does not have a settled definition in federal criminal law. We understood coordination to require an agreement–tacit or express–between the Trump Campaign and the Russian government on election interference. That requires more than the two parties taking actions that were informed by or responsive to the other’s actions or interests. We applied the term coordination in that sense when stating in the report that the investigation did not establish that the Trump Campaign coordinated with the Russian government in its election interference activities.— from the Mueller Report
That faint sound you hear is hundreds of philosophers paging through their thumb-worn copies of seminal books and articles about shared agency and collective intentionality and revving up their word processors to write lecture notes and articles.* I have not investigated this literature sufficiently to have useful views, but it is a rich topic of current investigation that bridges ethics, metaphysics, and philosophy of language and mind.
What does it mean to say, “We are doing something?” Is the “we” a real thing or just a shorthand for several “I’s”? If a bunch of people all run for shelter at the sound of thunder, are they coordinating? What if they take exactly the same actions as part of a dance? Does the “we” mean something different in the sentences “We all ran for shelter” and “We all performed a dance”? (This is from Searle.)
What if I say to you, “Let’s go for a walk”? Do I then have an ethical obligation to coordinate my itinerary and pace with you? (From Gilbert). Is the obligation just the usual one to honor a promise, or does it stem from my new relationship to you?
Let’s say that all the members of the Supreme Court believe that something is unconstitutional and issue a unanimous ruling to that effect. Later, the same nine people all think that dinner was awful. In one case, did the Supreme Court make a judgment, whereas in the other case, nine people made separate judgments? What if the nine issued a ruling and then found out that it was invalid because they weren’t properly in session at the time? Did they incorrectly believe that they were acting as a group? (Inspired by Epstein).
Robert Mueller says that whether the Trump campaign and Russia coordinated is a “factual question.” But it requires a definition of coordination. Apparently, the legal definition of that word (from statutes and/or precedents) is unsettled. But in any case, the deeper issues are philosophical–and not simple to resolve.
