The front webpage for the course is at phil101.jimpryor.net.
Here are Zoom links for course meetings and office hours.
Here is the Canvas page for course, where you’ll need to submit assignments. But most of the static information there will also be published below.
Prof Pryor’s office hours are on Mondays from 3–4:30 and Wednesdays from 1:30–3. His email is jimpryor@unc.edu.
Here are some guidelines about philosophical writing. See the front webpage for information about extensions and how you’ll be graded.
These are in reverse-order, so the newest posts will always be at the top. The dates are when the post was first made.
Readings are in a restricted part of this site. The username and password for these were emailed to you, and will also be announced at the start of class.
Here is a sparser evolving index of all the handouts, webnotes and readings we’ve used during the course.
Here are some notes:
Our readings for Monday (our last class) is this paper by Schwitzgebel and Garza. I’ll plan to run Monday’s meeting as a discussion section about this paper. Coming to class prepared to explore and argue about those issues will be a good way to boost your participation/engagement grade for the course, should you need to do that.
The final versions of your final papers are due on Thursday May 2 (eight days from today) at noon. At that time, we’ll also have a retrospective discussion of the class, held on the normal Zoom link for class meetings.
As I said in class, to this point we’ve only been considering which views you have most sympathy for: whether any way of giving the same I/O as Braden would is enough to have his mental states? (Or if souls are needed, is enough to be a suitable physical home for a soul that has his mental states.) Or whether the system has to be getting that I/O from a program that’s the same as Braden’s brain is running (or at least, a program that has close enough to the same structure)? Or whether the hardware is what matters: that is, some kinds of hardware running the Braden brain program would have his mental states, but there are some limits, and other kinds of hardware running that program would not have the same mental states. They’d just be faking it, that is, giving us the same behavior as Braden does in the same kinds of situations, when asked the same questions and so on, but not thoughts or feelings or any of that really going on inside.
For those who take the last kind of view, the question arises where the dividing line is between the “good” kinds of hardware and the “bad” kinds of hardware. You might think that only biological hardware can be “good.” Or you might think that what makes hardware “bad” is not that it’s inorganic, but rather that we designed and constructed it. Or you might have some other, perhaps more complicated view.
All of this is just mapping out the possible views, and figuring out where our sympathies lie. We haven’t yet been considering arguments for or against any of the views. What we’re tutning to now is a famous argument by John Searle called the Chinese Room argument, that’s meant to show that the hardware is what matters. The views that say all you need is the right program (or that all you need is the right I/O, though this view isn’t so popular these days) have to be wrong, he’s arguing. Because he’s going to describe one kind of hardware which is running the right program but (he says) definitely does not have the mental states.
The two readings assigned for today (listed under the Monday Apr 15 entry below) deal with Searle’s argument. The two readings assigned for Wednesday (also listed below) are easier reading, and continue developing these themes.
Remember your peer feedbacks are due by the end of the day (11:59 pm) tomorrow. I sent a Canvas announcement around explaining where to find the papers you’ve been assigned, in case you had trouble finding them.
Here are lecture notes on Other Minds and the Turing Test. These summarize ideas I’ve presented in class over the last couple of sessions.
Sorry I forgot to post the handout to the website before class. Here it is.
It’s likely that sections will continue discussing the range of cases set out on the handout, so try to get familiar with them beforehand. Bring the handouts to your section meetings, and bring them to class again next week.
Readings for next Monday (and the remaining classes after that) are posted below.
Remember the first drafts of your papers need to be submitted to Canvas by 11:59 pm on Friday. Just submit your drafts for the time being, but hold on to your work-in-progress files and work logs, because you’ll have to submit them when you turn the final versions of the papers in.
For our remaining classes, any quizzes given will be in-person only, and those who get them mostly correct will earn extra credit towards their final grade. These quizzes will be a bit more difficult than the multiple choices you’ve seen before; but doing well on them won’t take any special insights. You’ll only need to have followed the basics of the previous lecture or two, and be caught up with the assigned readings.
The readings that were assigned up until now are:
Here are our readings for the rest of the semester:
For Monday’s class:
Your final papers were originally on this schedule: first drafts due for peer feedback on next Wednesday, peer feedback due the following Monday, and final versions due at the start of our final exam session. We’ve decided to give you a few more days to work on the earlier stages. So now the first drafts will instead be due next Friday, Apr 19. I’ll be posting the instructions and paper prompts here this evening. Here are the second paper instructions.
We’ve been talking about computers made out of unfamiliar hardware, including mechanical devices instead of the electronic circuitry we’ve become used to. Here are some pictures, videos, and other links illustrating that:
Another kind of unfamiliar hardware we’ve mentioned involves organic components, such as bacteria or other cells, or DNA molecules, or perhaps neurons taken from an animal’s brain (or grwon in a lab). Here are some links about that:
We’ll be returning your exams soon and your midterm papers early next week. I don’t know yet how the grades on the midterm papers are distributed. But it’s clear that many of you will have done worse on the exam than you’ve done in your earlier work. We’re curving the results to some extent, but still half of you were not able to answer correctly even half of these questions, about the most basic ideas and positions that we and our reading have been developing over the past weeks. Our semester is running out, but if you’re able to put appropriate amounts of time and effort into improving your participation adnd engagement with the course, and developing your own final papers (and giving each other good constructive feedback to help them improve theirs), those are all still good opportunities for you to improve your grades, and also get more educationally out of this course.
Remember our in-class exam is at the start of class on Wednesday. At 9:30 we will continue discussing the possibility of machines/AIs having mental states/processes of the same fundamental shape as our own.
I realize your main focus for now will be on preparing for the exam. But here is some more relatively accessible reading on our new topics. (Some was already listed last week.) When you get the opportunity over the next days, continue reading through this list. You should aim to be caught up on all this reading by next Monday, Apr 8.
I’ve updated the notes on libertarianism to include discussion of agent-causation theory, as defended in the Taylor article assigned for today.
For instructions on turning in your midterm papers, see the entry below for Monday Mar 25. For information about the upcoming second in-class exam (of two), see the entry below for yesterday.
There is no section this week.
Next week, we’ll be starting our last unit of the course, on the possibility of machine minds. Here are some short stories to read for Monday:
Here will be our readings for next Wednesday:
Here are instructions for the second exam, which will be given in class next Wednesday.
Readings for this Wednesday are posted below (in the entry for Wed Mar 20).
Here are initial notes on libertarianism. I’ll expand that page after Wednesday’s lecture.
Here’s a short video giving a good overview of the problem of moral luck, that we discussed today, by Victor Kumar (6 min).
Optional: Here’s a longer video (another episode of The Free Will Show, that we linked to before) discussing the Problem of Luck for Libertarianism (38 min, Alfred Mele).
For the rewrites of your midterm papers, due at the end of the day on Thursday, we already gave you some instructions in items G4, G5 and G6 of the feedback page. Briefly reminding you:
Some more clerical instructions:
Here are webnotes summarizing today’s continued discussion of Compatibilism.
For Monday, read:
For next Wednesday Mar 27, read:
As I said at the end of class, we’ll be releasing the grades and feedback on your midterm papers later today.
Here are webnotes summarizing today’s discussion of Compatibilism.
For Wednesday, refresh yourself on the Lemos Chapter 2 I asked you to look at for today, and also read this next article. (I said van Inwagen in class, but that’s wrong, we’ve already read that before break. If you haven’t read that yet, though, then do get caught up.)
Your v1 paper grades and feedback has been posted; here is a page with general feedback.
Here is the quiz we took in-class today:
The first part of today’s lecture was reviewing and reinforcing things we introduced last time. At the end, we presented and discussed the Consequence Argument for incompatibilism. Here are notes summarizing the Consequence Argument.
Apologies to those Zooming for the very sub-optimal managing of where the camera is focused. We will try (the TAs will try to remind me) to handle this better going forward. Hopefully the audio plus the web summaries will help you track what was discussed. But Zoom is always going to be an inferior way to keep up with this course. We’re glad to provide it as a fallback to those of you who can’t be there in person, but we’re not able to make it equally good.
As you know, the first versions of your midterm papers are due tomorrow evening.
Here is the reading for our next lecture meeting, Monday Mar 18 after spring break:
Here are notes summarizing last Wednesday’s and today’s lectures on free will.
Readings for Wednesday:
We hope those of you who took the exam found it to be straightforward.
We’ll continue our discussion of free will in sections and in next week’s lectures. In addition to the readings for today, another required reading for Monday is:
Optional but strongly recommend are this additional paper:
And this YouTube video:
Don’t put off starting on your midterm papers. You should already now be settling on a topic, thinking about it, starting to take notes, and figuring out how to orgnaize them. Your best ideas and arguments may not come to you right away, but rather in the course of outlining/planning the basic structure of what you aim to say.
Here is general feedback on your expository writing exercises. Your TAs will be releasing the scores and individual feedback through Canvas.
Today’s class will be in-person.
We’ll be returning feedback on on your expository exercises soon — we’re hoping by tomorrow.
Here are instructions and prompts for your midterm papers. The first version of these will be due at the end of next week (before spring break begins).
As you know, on Wednesday we’ll begin with our in-class exam. This is designed to be relatively easy for those of you who are caught up on all the reading, have followed all the discussion so far in lectures and sections, and so on. Those of you who aren’t there yet, we hope it may prompt you to get there. At 9:30, we’ll collect the exams and begin introducting our next topic, free will. We posted some readings last week on this; here they are again:
A couple of you have asked for access to the in-class quizzes, to help with your studying for the exam. Here are the ones we’ve given so far:
With the first question on the Meeting 9 Quiz, Felix pointed out afterwards that the question’s phrasing was taking it for granted that physical bodies exist. (Else Option b wouldn’t be sufficient for being a dualist: you might think that only minds exist.) That’s true, and we are taking bodies for granted in this class. But I agree with Felix it would have been better if we had been more explicit here.
Sent out an announcment by Canvas, but noting here also: will also have to do today’s meeting by Zoom.
Here are lecture notes from today, on challenges to whether dualists can tell a plausible story about how souls interact with physical brains and bodies. Those notes also summarize the arguments that we didn’t get to yet, but will take up on Monday.
There’s no new reading for Monday. You can spend time budgeted for this course on preparing for the exam (see the entry below). Also, for next Wednesday, after the exam, we’ll begin discussing free will. There are some light readings to prepate for that discussion:
As I said at the start of today’s lecture: we’ll post the topics for your midterm papers (the first version of which you’ll need to submit by Thursday Mar 7) by Monday.
Here are instructions and a review sheet for our upcoming exam next Wednesday. Have a look at it as soon as you can, so that you’ll be able to ask us any questions this week.
I’ll send out a Canvas post tomorrow morning letting you know whether our class meeting will be in-person or again by Zoom.
Here are some lecture notes on Huxley.
Reading for Wednesday:
As announced on Canvas, I’ll have to conduct tomorrow’s class by Zoom. See [restricred/zoom.html] for the course link.
Here are more lecture notes from today’s dicussion of Leibniz’s Law.
Read for Monday:
Here are the instructions for the expository exercise, which is due this coming Monday, Feb 19.
Sections meet this week, but no lecture next Monday (it’s a Wellness Day).
For next Wednesday, continue reading the van Inwagen. You should aim to get on top of at least all the arguments for dualism (pp. 230-245). In class we’ll still be talking about the first argument, using Leibniz’s Law, but the other arguments for dualism will be prompts for your expository writing exercises. We’ll give you more instructions about those next week. They wll be due on Monday Feb 19.
Starting on Feb 19, we’ll be discussing different options that dualists have for how to think souls and bodies are causally related. van Inwagen raises this early on in his text, around pp. 226 – middle p. 229 (this is where he uses labels like “interactionist” and “epiphenomenalist”). These issues play a large role in his discussion of arguments against dualism, starting on p. 260.
Read for Wednesday:
As I said before, the whole reading is long and complex, so work on making progress on this during this week and next; for Wednesday please read at least up to top p. 233 (including his discussion of the differences between dualism and physucalism, and the “first argument” in support of dualism).
When trying to get on top of the van Inwagen reading, you should really try to map out for yourself which paragraphs are explaining core commitments of dualism (things you have to say, to count as a dualist), which paragraphs are explaining options that some dualists might take but others reject, and so on. The same with physicalism. And which paragraphs are presenting the first argument for dualism, which the second, and so on.
When you get to van Inwagen’s discussion of a “second argument” for dualism, you’ll notice that it’s longer and more complex than his discussion of any of the other arguments, either for or against dualism. It will take some work to follow the backs and forths and understand what’s happening. It might help to have some signposts and ways of breaking that long discussion of the “second argument” into smaller pieces. Here are my suggestions for how to do that:
So in the end, even though the physicalist is giving us less than we’d like, and still leaving things unsatisfyingly mysterious, arguably so too is the dualist. If van Inwagen is right, the considerations of this “second argument” don’t really end up giving us more reason to accept dualism.
The lecture notes for today’s meeting were already assigned to be read in advance.
We’ll continue to discuss the debate between physicalists and dualists over the next few weeks. Our reading for upcoming classes will be some parts of the Gennaro textbook (I already assigned pp. 5-21 to be read for today, and will assign more later), a longer reading from Peter van Inwagen that I’ll talk about in a moment, and the following webnotes:
Our thin textbooks like Gennaro’s may be clear and straightforward enough that you don’t need to work hard to understand the structure of their text. The ideas may be hard, but I hope it won’t be a challenge to follow these texts’ discussion of them. Other readings we look at in the course will demand more work from you as a reader.
This includes a reading selection from Peter van Inwagen’s book Metaphysics. As philosophical writing goes, this reading should be clear and accessible to beginners in philosophy like yourselves. At least, individual sentences and paragraphs should be clear. But it is a longer and more complex text than anaything we’ve looked at so far. So you should expect to spend some time working on understanding it. You should also expect to read it more than once.
The author’s last name is “van Inwagen”; he was an important metaphysician based at Syracuse and Notre Dame, but is now retired from teaching. (He still sometimes visits at Duke.) Note that our selection has three parts (all in the linked PDF). First an “Introduction to Part 3,” where van Inwagen contrasts “rationality” to some ways of understanding “intelligence,” and explores what’s included in our concept of “rational.” Next is Chapter 10 of his book, which distinguishes two large proposals about “what kind of thing” rational beings like us are. These are views that philosophers call “dualism” on the one side, and “physicalism” or “materialism” on the other. The initial parts of Chapter 10 explain what these competing proposals say, and then from p. 230 to p. 245 discuss four arguments that are supposed to support the dualist side. In fact van Inwagen mentions “five arguments,” but the fifth is in part of his Chapter 11 that our reading selection skips. We resume again on p. 260, where van Inwagen discusses four arguments that are supposed to support the physicalist side.
Unlike the earlier long reading from the Dr Dolittle book, here it won’t be enough to just get the big picture and overall feel of the text. You need to go through the reading carefully and understand the details.
We’ll spend several meetings talking about issues in this reading. I’ll ask you to have started reading it by Wednesday of next week, and to have read the whole thing by Wednesday Feb 14. Some of the issues discussed in this reading we’ll only be turning to in class even after that.
For this coming Monday Feb 5, I’m just asking you to read the Guidelines on Reading, to help prepare you for these readings that need more intellectual work from your side. But since the van Inwagen reading will take a while for you to master, you may want to get started on that early.
Handouts to be discussed in class today:
Optional: If you want to read more about Alex the parrot, here is a Wikipedia entry, and here is an older NY Times article.
Readings for Wednesday:
I had proposed some additional reading for Wednesday, but in fact you only need to read them before sections on Friday, so I’ve updated these pages to reflect that. Here again is the next reading:
Here are some notes on these readings bumped from earlier.
For the “Star Witness” reading, note that the “Reader Assignment” at the end is just part of the original text. It’s not a written assignment for our course. Also, the specific nature of the crime the parrot may be a witness to is not crucial to the story. For our purposes, neither do we need to sort out the legal issues discussed in the text, such as whether witnesses need to be cross-examinable. We’re reading and discussing this text just to get leverage on questions about what cognitive abilities it’s reasonable to think a parrot might have, and why.
One of the people taking part in that dialogue is named Mary Godwin. Some backhistory: William Godwin and Mary Wollstonecraft were philosophers in late 1700s. They had a daughter Mary Godwin (Mary Wollstonecraft then died shortly after childbirth) who grew up, got involved with the poet Shelley and wrote Franksentein. The mother was born with the name Wollstonecraft but took her husband’s name Godwin on marriage; the daughter was born with the name Godwin but took Shelley’s name when she eventually married him. The dialogue refers to the mother as “Mary Godwin” and it’s a story about her that’s discussed in the first chapter.
Thomas Paine wrote The Rights of Man in 1791, arguing (in defense of the French Revolution) that all citizens (not just aristocrats) had “natural rights,” and that they can/should revolt when their government doesn’t protect these rights. Paine also argued for education and welfare reforms. Around the same time, Mary Wollstonecraft Godwin wrote A Vindication of the Rights of Woman, arguing that women deserved “rational education” (versus just “domestic education”), and that they had the same natural rights as men.
Thomas Taylor then wrote A Vindication of the Rights of Brutes in 1792; this was meant to be a satire of Paine’s and Godwin’s arguments. The absurdity of counting animals as persons was meant to imply it was also absurd to count poor servants and women as equals to their superiors.
The dialogue invokes this historical exchange for several purposes: (1) to remind us that Paine and (the orginal) Godwin had to argue that all men, and women, deserved the same rights as others — it took work to overcome people’s doubts about this; (2) to remind us that the arguments Paine and Godwin offered had to do with reason and intelligence, which as Taylor observed, are present to some degree in animals too; (3) the modern Godwin agrees with Taylor that there’s a “slippery slope” from the arguments of Paine and (the original) Godwin to accepting that animals also have rights. Taylor thought therefore those arguments must be wrong (hence his satire). The modern Godwin instead endorses the arguments and this further conclusion.
This semester a Film and Philosophy class is screening a variety of philosophy-related films on Thursday nights in Caldwell 105, at 6 pm. Anyone is welcome to drop in. Here is the schedule:
Some were confused about the reading for Monday. The linked PDF has all the sections I am recommending you to read. The PDF is long, but the material to read adds up to about 87 pages. That’s pretty long, but as I said earlier, this reading (unlike others for the class) is one where you don’t need to master detaila and can read through quickly and shallowly. I will remind you of some key parts when we meet next week.
Normally I have office hours on Monday afternoons from 3-4:30 (also on Wednesday afternoons at 1:30), but this coming Monday, Jan 22, I won’t be able to hold office hours. I’ll be glad to Zoom with you on Tuesday or meet on Wednesday afternoon instead.
Here are notes summarizing some new material introduced today:
The second page discusses what might unify and be distinctive to all mental states. I touched briefly on that question at the end of today’s class, but didn’t have time to talk through privileged access. I’ll briefly address that at the start of Monday’s class. Then we’ll begin discussing mentality in animals.
Read for Mon Jan 22:
This is a rather long reading (around 87 pages), but you don’t need to master details. Its role in our course is to give us some background familiarity with what research into animal communication looks like (especially, how it argues), what results this research has produced, and what the controversies are. It also introduces us to a distinction between the general category of communication systems, and more specific structural properties that researchers see as fundamental to human language (and that seem to be mostly absent from animal communication).
Read by Wed Jan 24 Fri Jan 26:
(Some notes on these two readings moved to the Mon Jan 22 entry.)
We’ve moved our lectures to Coker Hall (CO) 201. We’ll be meeting there from now on, instead of in Hanes Art Center.
I sometimes bookmark YouTube videos that look like they might be relevant to this course. Viewing these is entirely optional, but you may find some of them useful or interesting. I’ll link to two playlists now, more later in the term. Note that I’ve only previewed some of these videos, and I can’t vouch for any of them. Many times I’m just adding them to the playlists based on their titles, or familiarity with the channel that published them. If you come across any that you think are dumber or less helpful than average, or inappropriate in some other way, please let me know. Also if some of them are especially good, or you come across some other good videos on these topics that I haven’t included, please also let me know.
(Also anyone want to propose a better name for the series?)
Here are the first two playlists:
Our first class meeting is on Wed Jan 10. I’ll introduce you to our course topics and to what philosophical activity looks like.
There is no reading assigned before that meeting. But there is a substantial chunk of reading you should do afterwards, and be ready to discuss/ask questions about in our subsequent meetings. That is the group of web pages at this link:
(The last of those pages is a Glossary that I hope will be useful but is less important than the earlier pages.) Also this brief selection:
(Pages with a “restricted” URL like that one need a username/password, which have been emailed to those registered for the course.)
Recitation sections meet starting this Friday, and may begin discussing some of these materials. We’ll also provide an opportunity to raise questions about them when we meet for our second lecture, which is Wed Jan 17. (No classes meet on MLK Day, Mon Jan 15.)
Those pages already have developed explanations of the relevant concepts, and I’m not planning to repeat/summarize those in class. But we will consider the Review lists at the end of the pages, and whatever you think is confusing or it’d be helpful to explore further, let’s discuss.
