 Another reservation with invoking intention at this point stems from consideration of unintentional collective action. Appealing to intention as Searle does would seem to preclude what some see as a real possibility: that there are φ-ings done jointly in some robust sense, but which are not intended under any description. One possible example would be our jointly bringing about some severe environmental damage. This might come about as a side effect of each of us pursuing our own projects. No subject intends the severe environmental damage, under any description: no single individual has enough of an impact to intend anything that would count as severe environmental damage, and as a collective the polluters seem not to be sufficiently integrated to count as a subject of intention. Whether this really amounts to a counterexample will depend on whether our damaging the environment was joint, a genuine exercise of shared agency.
