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

[glen]

I'm still attracted to Rosen's closure to efficient cause. Your flashlight example is classified as non-agent (or non-living ... tomayto tomahto) because the efficient cause is open. 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
