Rather than beings and behaviors, these things that act and these things that do, I proffer this: postures and gestures.
A posture is a way of standing towards things. A gesture is a way of operating with things.
We stand towards things, and we operate with things.
A posture is akin to a state, only a temporal state. A gesture is a type of action — type, yes, but a type of action.
To be affirmative is to have a posture of standing towards the world with generosity and enthusiasm. To be ironic is to gesture the lack of veracity of expression — which can be either affirmative or negative or both affirmative and negative.
A posture — affirmative, negative, disdainful, joyful — can entail certain gestures — the affirmational tends towards the welcoming, elicitive greeting. But that relationship is by no means disease/symptom, truth and derivative: each inflects the other. Postures and gestures are not strictly parallel modes.
By assuming these anything but absolute figures, we avoid the being/attribute dichotomy, as if there were first bodies and then the thing that happen to them. A posture is not a being but a way of being, a perspective, a pov on the scene. A gesture, meanwhile, is any of the number of ways of doing this or that: reversing, exaggerating, downplaying, cutting and pasting.
Together, they begin to proffer an ontology in and of motion, events, time.
