Note further that slot, class, and role are also relevant to nonverbal behavior. Note that in discussing physical events within a society, the role of an actor could be his intention or purpose. In an American court of law, for example, a verdict may depend upon the jury's decision as to whether or not a person intended to kill someone else, or whether it was an accident which he tried to avoid. Our interpretation of such events cannot be autonomous in relation to our beliefs or judgments or guesses about the purposes of the people acting. Intentions or wishes can be made explicit in a sentence like I wish you would close the door.
Nonverbal actions can also express such intentions.
The actor above, for example, could pretend to shiver strongly, and then gesture toward the door. In some instances, a speaker may lie about his intentions or be confused. Nevertheless, the importance of implicit as well as explicit intent, purpose, and cause must be taken into account. Naive mentalism and naive physicalism are perfectly consistent with each other. Indeed, as far as we know anything about how the world works, they are not only consistent, they are both true.
