And they probably know other people in the department who teach things that might be interesting to a STEM student even if that student hardly knows it yet.
Logicians are somewhat different in studying formal systems, and there are strong links to (foundations of) mathematics. But logics are typically developed and analyze to study some otherwise philosophically motivated questions.
Few generalisations hold of philosophy departments across traditions and regions, and this is untrue of departments in the analytic tradition of which Dennett was part. Philosophical logicians are often interested in more than logic for logic’s sake, and other philosophers share that interest; see e.g. Williamson’s /Modal logic as metaphysics/.
Perhaps finding it confusing is a recent development.
That's an interesting point.
I think there's also a cost to that-- philosophy lugs around a lot of pre-scientific baggage that is poorly specified but historically important. Free will comes to mind, especially within the Christian history of resolving the apparent contradiction of horrific natural/manmade evils existing in the face of an omniscient, omnipotent, and benevolent god.
There are of course other historical contexts to notions of free will. But when philosophers talk about any of these in places where laypeople here them, it seems like those historical contexts are gone and they end up strongly implying a general purpose free will that is neither well-specified or in some cases even coherent.
It would be like a bunch of programmers debating "functions," with one meaning functional programming, another meaning any programming language where functions are a first-class citizen, and yet another meaning the set of all keywords "function" or "FUNCTION" in any programming language in history. That's not going to be a fruitful discussion.
So I'd speculate people in STEM can smell the lack of systematic thinking in some of these discussions and unfortunately throw the baby out with the bathwater.
Edit: clarification
It be be tautological, but a lack of systemic thinking makes a discussion bad philosophy, or epistemic bunk as they say in the trade.
Or maybe his point, in a discussion like this on HN, a lot of people are jumping into the conversation in-the-middle, without catching up on the history.
Perhaps, but seeing poor thinking in others is a lot easier than seeing it in oneself. I don't recall encountering any STEM folks who haven't made a logical/epistemic/other error on the proposition of whether we have free will. It is one of those questions that seems to put the mind into some sort of a weird downgraded mode.
This entire comment section is...interesting.
>implying a general purpose free will that is neither well-specified or in some cases even coherent.
To the contrary, I find that it is the layman who has an airy-fairy conception of free will that couldn't possibly exist, while the philosophers are generally more down-to-earth and use "free will" that normal people use the term in a non-philosophical context.
>So I'd speculate people in STEM can smell the lack of systematic thinking in some of these discussions and unfortunately throw the baby out with the bathwater.
I'm not sure if there's any baby in the bathwater if philosophy lacks systematic thinking, if by "lacking systematic thinking" you mean something like "not thinking definitions and arguments through". Luckily it doesn't seem that philosophy does this. But maybe I'm misunderstanding you - maybe you're talking about the philosophical discussions that laymen generally overhear, which tend not to be discussions held by philosophers but by other laymen. And I do think you would be right to say that these discussions generally aren't very coherent, and reflect poorly on philosophy as a discipline.
It's like the first programming language you learned. It will shape your perception of what programming is all about for a long time afterward, and might even turn you away from programming altogether. But there are lots of programming languages, and they're just different ways to make the same silicon do something interesting!
The silicon argument might be right if we treat it on its own. Input, process and output. But one think of the system where the silicon or multiple of them plus some analogue or biological input and output. It is not the same. The process affect the speed and response … you can imagine one use lisp, basic or cnn to drive a car … can you.
The turning complete is not physical as above and real world ish. Hence it sound all true. But people forgot we do not have unlimited memory. Our tur8ng complete is in practice not.
To sum it all may be we kick human out of the loop all silicon and human language might have a chance the same using the same language (but still physical real world above …)
Philosophers shoud better stay away from physics. Not saying here, that the thought experiments can't provide valuable insights. It's just they can't be used to define the truth about the reality.
FWIW, I have also seen the dismissive STEM attitude toward the philosophical tradition. It helps to remember that the philosophical tradition predates the scientific tradition significantly, and that it does not take logical positivism or reductionism as givens. Having studied both disciplines, I feel like philosophy has seriously enhanced my understand of the world even if I don’t use it in my day-to-day scientific work.
