[FRIAM] What is an agent [was: Philosophy and Science}

[Prof David West]

Where angels fear to tread, dave rushes in.

Question 1) seems, to me, to be nonsensical; or hopelessly anthropocentric; or, unanswerable in any generalized or abstract form.

Paraphrasing question 2) — what set of observables (behaviors) must be present before We/I can assert, "*t***hat *thing is an agent.*" Assuming such a set exists: a) it tells me nothing about the "internals" of the thing; and b) it tells me little about anything except how We (assuming some consistency among all human beings) go about naming / categorizing things. I would also bet money that any such set is culturally grounded and that it is unlikely that any "universal" set exists. Certainly no "universal" set shared by humans and our elusive alien neighbors.

If we were to examine the inhabitants of any set of things that came about via question 2), why would we expect any commonality among the "conditions" (state?? characteristics?? patterns of same???) internal to each member? Granted, there might be subsets of the set (e.g. all instances of a human being, or a dog, or, for some, an AI) where we would expect and find some kind of, at least, statistical commonality. I say statistical because there are always outliers and exceptions.

Another issue, implied by the way question 1) is phrased, concerns the possibility of knowing the train of events, steps in an evolutionary process, engaging the "internals" of an entity as it proceeds from non-agent to proto-agent to agent. How can this be anything other than idiosyncratic?

As to explanation vs. description: given any "description," the number of "explanations" is infinite—or, at least co-extensive to the number of "explainers." No matter what Pierce might hope, consensus is unlikely.

Whatever else might be said about the relation between explanations and descriptions is that descriptions are states of affairs taken for granted by explanations.  If you ask me why the chicken crossed the road, my answering your quest commits me to the premise that the chicken did indeed cross the road.

And if you were looking  to define agents in terms of the  internal mechanism that makes agency possible, what precisely is the state of affairs, behavior, what-have-you, that such agents are called upon to explain.!

An explanatory  definition identifies a phenomenon with its causes, bypassing  the phenomenon that raises the need for an explanation in the first place?   What is the relation between agents and their surroundings that makes them seem agentish?  Having answered that question, your explanation now comes into play.

The thing about them that makes them seem less agenty is that they have only one means to do so. Give that thermostat a solar panel, and a heat pump, and an oil furnace and have it switch from one to the other as circumstances vary, now the thermostat becomes much more agenty.

In what important way is that different from a flashlight? They both have energy storage systems (batteries). Does it really matter that the garden light "recharges itself" rather than relying on a more direct outside force to change its batteries? And they both have on-off switches. The flashlight's is more conventional whereas the garden light's is a light sensor. Does that really matter? They are both tripped by outside forces.

Now, attach sensor and effector to the flashlight so that it can flick it*self* on when it gets dark and off when it gets bright, then that (partially) closes it. Maybe we merely kicked the can down the road a bit. But then we can talk about decoupling and hierarchies of scale. From the armchair, there is no such thing as a (pure) agent just like there is no such thing as free will. But for practical purposes, you can draw the boundary somewhere and call it a day.

But a boulder crashnng down a hill and destroying something at the bottom is reasonably called "an agent of destruction." Perhaps this is just playing with words: "agent" can have multiple meanings.  A writer's agent represents the writer in negotiations with publishers. Perhaps that's just another meaning.

Does this suggest that an agent must manifest a certain minimal level of complexity in its interactions? If so, I don't have a suggestion about what that minimal level of complexity might be.

Here are the first few sentences from the article overview.

The philosophy of action provides us with a standard conception and a standard theory of action. The former construes action in terms of intentionality, the latter explains the intentionality of action in terms of causation by the agent’s mental states and events.

(To be fair, the article does consider the possibility that there can be agents without these properties. But those discussions seem relatively tangential.)

His straw man philosopher is a dedicated *armchair* philosopher who spins theories without paying attention to scientific practice and contributes nothing to scientific understanding. He misses that scientists themselves are constantly raising obviously philosophical questions and are often ill-equipped to think about them clearly. What is the correct interpretation of quantum mechanics? What is the right way to think about reductionism? Is reductionism the right way to think about science? What is the nature of consciousness? Can you explain consciousness in terms of neuroscience? Are biological kinds real? What does it even mean to be real? Or is realism a red herring; should we be pragmatists instead? Scientists raise all kinds of philosophical questions and have ill-informed opinions about them. But *philosophers* try to answer
