These posts 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 will be announced in class and on Canvas.
Here is a sparser evolving index of all the handouts, webnotes and readings we’ve used during the course. Or you could look under the Canvas “Modules” tab.
As discussed in Quiz 4, being a Dualist doesn’t commit you to any particular view about which creatures do and don’t have souls. Being a Dualist in the sense of holding “Thesis D” gives one lots of latitude about what else a Dualist will say. Even if you agree with them about D, you may disagree with their other views. Dualists don’t have to think that people are identical to their souls (they might be identical to a combination of a living body and a soul); they don’t have to think people can exist after the body dies (for example, if people are such combinations, there is no combination anymore when there’s no living body). Dualists may have different views than you do about what AIs or animals are capable of, and whether they have souls.
I’ve posted two Quizzes to Canvas, named Quiz5 and Quiz6. I’ve made them due by the end of Tuesday; and there will be no further quiz for next week. They both cover the material we’ve done up to this point in the class, so if you’ve done the reading and understand what we discussed in class yesterday, you should be prepared already to do both quizzes. But if you want to wait and ask more questions when we meet on Monday, you’re free to do that instead.
I’ve been updating the Review sheet as we go, and for reference, here are all the previous quizzes with model answers:
In class I said we’d be reading an older article for next week. That was the original plan; but after thinking more about our compressed schedule, I think it will be better to drop that reading and proceed differently. What I’ll ask you to read for Monday instead is more of the van Inwagen text that you’ve already read some pieces of.
Peter van Inwagen was an important metaphysician based at Syracuse and Notre Dame, but is now retired from teaching. He currently has an affiliation as a “Research Professor” at Duke, and sometimes leads grad seminars there.
Note that his family name is “van Inwagen.” Some people’s surnames/family names are made up of more than one word. For example, when you refer to the Colombian author Gabriel García Márquez, you don’t say “Márquez said so-and-so.” You refer to him as “García Márquez.” There are various and sometimes complicated histories of how people get compound surnames like this. Sometimes it’s the result of taking a compound name upon marriage (Kim Kardashian West). Sometimes it’s the result of the person’s parents keeping different surnames from each other. Sometimes the explanation lies several generations back (Helena Bonham Carter). In European-derived names, a common pattern is for surnames to begin with “von” (German) or “van” (Dutch) or variations on “de” (several Romance languages). These initial words are part of the surname. You don’t talk about the painters Gogh or Vinci, or the actors Niro or Sydow or Damme, or the director Palma. You talk about van Gogh, da Vinci, De Niro, von Sydow, Van Damme, and de Palma. Sometimes the person (or their parents or more distant ancestors) chose to capitalize the initial “De” or “Van,” other times not. In van Inwagen’s case, the “van” is not capitalized. (You can capitalize it at the start of a sentence.) If you’re going to refer to him, you should use his full name “Peter van Inwagen” or his surname, which is “van Inwagen.” Not “Inwagen” or “Vaninwagen.”
Our reading is from van Inwagen’s book Metaphysics. The whole selection I’ve linked is long and complex, and we’re not reading it all at once. The linked PDF has three parts. First there’s 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 we’re calling “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 I’ve left out of the selection. The PDF resumes again later in Chapter 11, on p. 260, where van Inwagen discusses four arguments that are supposed to support the Physicalist side.
The parts you’ve read already go to the top of p. 233. This covers the differences between Dualism and Physicalism, and the “first argument” for Dualism that van Inwagen discusses (which uses Leibniz’s Law).
For Monday, we’re going to read more from that PDF. Continue reading van Inwagen’s discussion of the “second argument” (top p. 233–top p. 240) and “third argument” (top p. 240–top p. 241). We’ll come back and look at his discussion of a “fourth argument” later in the semester. As I said, he also mentions a “fifth argument,” but he presents and responds to that in a section of his book that our PDF skips.
The “second argument” van Inwagen discusses is based on the idea that it’s mysterious and hard to understand how physical things could have thoughts and sensations. You’ll notice that his discussion of this argument is longer and more complex than his discussion of any 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 you to have some signposts and ways of breaking that long discussion of the “second argument” into smaller pieces. Here are 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 “third argument” van Inwagen discusses is based on the idea that we don’t seem to occupy the same space as our bodies do.
The thin textbooks we use this term, like Gennaro’s, may be clear and straightforward enough that you don’t need to work hard to understand the structure of their text. Their ideas may be hard, but I hope it won’t be a challenge to follow those texts’ discussion of them.
But other readings we look at in the course, including the van Inwagen reading, will demand more work from you as a reader. As philosophical writing goes, this text should be accessible to beginners in philosophy like yourselves. At least, the individual sentences and paragraphs should be clear. But it is a longer and more complex text than other things we’ve looked at so far. You should expect to spend some time working on understanding it. You should also expect to read it more than once.

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. This webpage tries to give you some guidance about how to do that:
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.
The van Inwagen PDF I’ve been linking to is a “clean copy” of our reading. Here is an alternate “annotated copy”, where I mark in pencil the topics of various paragraphs, underline important claims, and say where the discussion of some topics begins and ends (sometimes these extend over several pages). As I say in the Guidelines on Reading, marking up texts in this way is an extremely useful tool to help you understand and think about the readings better. I like to do it in pencil on hard copies, but you can also mark up documents in many PDF readers, or you can take notes for yourself in a separate notebook or file, sketching a brief outline of what you’ve read. (And maybe some reactions or questions that occur to you while you’re reading.) You won’t do this for everything you read, but it is a great habit to develop as your default approach to texts that will be important to what you’re studying or thinking about.
You need to do this yourself on texts to get the real benefit, and develop your skills for how to read closely. I’m just showing you this copy of the van Inwagen text with my own annotations to help you see how to get started.
For those of you who missed today’s class, here is the handout.
I will post a quiz to be completed online by Sunday evening, and our readings for next week, later.
Grades for your Quiz 4s were posted. Here are model answers to the quiz.
Our (substantial) reading assignment for tomorrow is linked below. We may well not be able to get through discussing all of it tomorrow. But we’ll see how much we can do. We’ll have another out-of-class quiz this week based on what we are able to cover. It will again be due Sunday night.
Today we’ll discuss the readings up through the introduction of Dualism and Materialism. This coming Monday, Feb 9, we again have no class (Well-Being Day). For Wednesday of next week try to read all of the remaining selections I had posted. We’ll see how much of it we’re able to get through next week.
I’ll post Quiz 4 on Canvas, to be completed using the Lockdown Browser by 9 pm on Sunday.
Another class canceled because of weather. I’ve updated the due dates for the readings in the entry below. We’ll probably have another out-of-class quiz due the end of this week.
Here is the plan, assuming that we’ll still be having class tomorrow.
We’ll do this week’s quiz outside of class. It’s due by the end of the day Wednesday. I sent you an announcement about that through Canvas.
The readings that were assigned for Monday will be discussed tomorrow (and are addressed in the quiz). I’ve shifted some of the upcoming scheduled readings and topics forward. Here is what you should read for next Monday, Feb 2 Wed Feb 4:
Here is what you should read for next Wednesday, Feb 4 Wed Feb 11:
That’s a lot of reading for next week, so give yourself enough time for it.
The following Monday, Feb 9, we again have no class (Well-Being Day). For Wednesday of that week, our reading is was — let’s see how much of it we can still get through for that day: 

I posted your quiz grades and some model answers to the quiz. (See link under yesterday’s entry.)
I just saw on alertcarolina.unc.edu that Monday classes are cancelled. Do what you can to do the reading I assigned for Monday before our next meeting, whenever that is. (I suppose there’s some chance that Wednesday classes will end up getting cancelled too.) Also check in here and I’ll most likely add some additional reading. I may make next Wednesday’s quiz one you can complete online outside of class, even if we meet on Wednesday.
If you get stuck in some situation like a power outage where it’s not feasible for you to keep up with the coursework, just deal with your situation as best you can, and let me know about it when you have the opportunity to do so. I know we’ll need to accommodate each other.
I will post some notes summarizing yesterday’s discussion of animal mentality:
Those pages also have some optional links if you want to dig further into details.

For Monday, please read these selections:
Here are some notes on these readings:
For the “Star Witness” reading, the “Reader Assignment” at the end is just part of the original text. It’s not a written assignment for our course. Also, for our purposes, we don’t 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 back-history: William Godwin and Mary Wollstonecraft were philosophers in late 1700s. They had a daughter Mary Godwin (the mother 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 (that is, the mother) 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. Taylor thought that the absurdity of counting animals as persons (as he pretended to argue for) implied it was also absurd to count poor servants and women as equals to their superiors.
Our dialogue invokes this historical exchange for several purposes: (1) to remind us that Paine and (the historical) 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 (future, in-the-book) Godwin agrees with Taylor that there’s a “slippery slope” from the arguments of Paine and (the historical) Godwin to accepting that animals also have rights. Taylor thought therefore those arguments must be wrong (hence his satire). The future Godwin instead endorses the arguments and this further conclusion.
Sorry it took me a while to prepare these notes, but have a look at these pages before class tomorrow. It’s just a few pages. We’ll talk through the concepts at the start of class. Some of the fundamental ideas from these notes will be on the quiz, along with an invitation to describe interesting and surprising facts about what you learned from reading about animal mentality.

I also updated the Review sheet.
I posted your quiz grades. These were graded to a relaxed standard, and by that measure, everyone did reasonably well. The grades ranged from B+ to A. Almost everyone made a few mistakes, but I gave partial credit if, for example, you marked the correct answer for a question but also marked an incorrect answer. An A- grade roughly corresponds to getting between one and two full questions wrong. Here is a set of model answers to the quiz, which I encourage you all to review. I hope that even if you were still somewhat confused about a concept while taking the quiz, the process of comparing the model answers to your own will help improve your understanding.
Apologies again for my own confusion on Wednesday about what time class ends. I was starting to explain one way of categorizing mental states that philosophers find helpful, that distinguishes between the state’s being an occurrent episode or happening and its being more dispositional. I’ll post notes about that contrast, plus a second set of categories philosophers find helpful, later today or tomorrow. Have a look at those notes for our next meeting on Wednesday, along with continuing to browse videos or article about animal mentality.
Here is the Review sheet of material that’s candidates for being on our quizzes or finals. It was part of the one handout distributed in class today. As the course progresses, I will add more material to the Review sheet.
As discussed in the syllabus, for normal class purposes (including when we break into small groups for discussion), our classroom policy will be no devices: laptops, tablets, or phones. If there’s something urgent you need to use a phone to handle, please excuse yourself and go handle it in the hallway.
For quizzes and the final, you’ll have the option to complete them handwritten, or using a lockdown browser on your laptop or tablet. That’s an exceptional situation, when devices are allowed. Either way you proceed, you’ll be allowed to consult any printed or written notes during the exam, but not any device (and if you’re using the lockdown browser, it won’t allow you to switch to a different app or window). Note that the time to complete the quiz will be limited.
On Wednesday, we’re going to take up our first main topic, that of animal mentality or cognition. We’ll get to some philosophical readings on this. (I have them on the Calendar for Mon Jan 26, but we may end up adjusting that.) Before we do that, it will be helpful for you to learn about surprising things that some animals can do, and things they can’t do. The exact details here aren’t going to matter so much for our discussion. But it still will be helpful to have a rough feel for the details.
There are different ways to do this.
Here is a page of links to popular science and news articles and videos about animal mentality. (You can also search on your own on YouTube or Google for keywords like “animal cognition” or “intelligent animals.”)
I don’t expect anyone to try to read/watch all of those. But I do ask you to make a good faith effort to spend time browsing some of them, or doing your own research, over the next week or so. I will be inviting you to summarize and react to some of what you learn on our second quiz (on Wed Jan 21).
Another option is to read some of this selection from a book about animal cognition in general, and their linguistic abilities and limitations in particular:
That PDF looks long, but if you go through it there’s a lot of partial pages. It looks to me to sum up to about 85 pages altogether. I think it’s a useful overview of the kind of information we want to be drawing on. But as I said, we don’t need to master the exact details. You’re welcome to read all of that selection, but I’m not requiring or expecting that you will do so.
And I don’t mind if some of you choose to skim the whole Dr Dolittle selection quickly; while others get interested in some of the details in one section and read there more closely, never making it through the whole text; and others instead just watch a handful of YouTube videos. Browse through these links and see what catches your attention. For this initial reading about animal mentality, I’m just going to trust that you’ll each put in good faith efforts to read/watch/learn some more about the surprising things some animals can and cannot do. We can share highlights with each other in class.
Our later reading assignments won’t be so free-form as this. We’ll generally all want to be looking and talking about the same texts. But this seems to me a useful and interesting way to start off.
For those of you who missed today’s class, here are summaries of what we discussed. See below for links to the reading to do for Monday.
Our first class meeting is on Wed Jan 7. I’ll introduce you to our course topics and talk about what philosophical activity looks like — what kinds of tools and strategies philosophers use for answering questions.
There is no reading assigned before our first meeting. But there is a chunk of reading you should do afterwards, and be ready to discuss/ask questions about in our subsequent meetings. That starts with the group of web pages at this link:
That link leads to a list of five pages; the most important for now are the first three. Skim the fourth too, but it may be harder and we’ll come back to it and discuss it more carefully in a few weeks. The last page is a Glossary that I hope will be useful but isn’t important for you to memorize.
Those pages already have developed explanations of many of the concepts we’ll be relying on this semester, and I’m not planning to repeat/summarize them in class. But I will take questions about the material on Monday, and we’ll talk through the Review lists at the end of the pages. Come to class next week with ideas and questions about what you find confusing or would be helpful to explore further.
The first of our Wednesday quizzes, on Wed Jan 13, will cover those materials.
For Monday, also read this brief selection:
(“Pojman” is the author’s family name.) Pages with a “restricted” URL like that one need a username/password, which will be announced in class and on Canvas. You should only need to enter it once per device.
Have a look also at this short page:
It will help you with the kind of task described in the Pojman reading.
