It Pays to Believe?

- Links to several articles on the argument.
- Here's an audio interview on the argument and Pascal's entire work Pensées.
- NOTHING TO LOSE? Is there really not much to lose in this wager? This cartoon thinks otherwise.
- WHICH GOD? With so many religions out there, which God should we believe in? This cartoon dinosaur has the most practical solution.
- More on decision theory, the branch of math Pascal uses to argue that belief in God is a good bet.
- Some related entries in the Stanford Encyclopedia of Philosophy: evidentialism vs. nonevidentialism, religious versions of nonevidentialism (or fideism), other pragmatic arguments for believing in god, and Pascal's other contributions to philosophy.

Bad Things to Such Good People
Here are some links on the problem of suffering.

This is a great introductory article on the problem of suffering.
- There is a collection of resources all about the problem of evil, including criticisms of several different responses to the problem. I mean, wow.
- I'd like to highlight one article in particular: a discussion of the "God works in mysterious ways" response: do we have enough evidence to believe that there is a reason for all the suffering in the world, but humans aren't smart enough to understand what that reason is?
- And here's a video talk on the humility response.
- Does everything happen for a reason? This cartoon dinosaur has an interesting take on that question. (T-Rex also occasionally wonders why bad things happen to nice people, and whether we're in the worst possible world.)

The Importance of Being Stochastic
Here is a bunch of links related to our natural tendency to misinterpret randomness as if it's an intentional pattern:
- Most of us are pretty bad at statistical reasoning.
- Here's a review of a decent book (The Drunkard's Walk: How Randomness Rules Our Lives) on this topic.
- What was that infinite monkey typewriter thing we were talking about in class? Someone recently tried it! Well, sort of.
- A radio show I love recently devoted an entire episode to probability.
- Another radio show I love ran a great 2-part series on the screening for diseases called "You Are Pre-Diseased".
- What's up with that recent recommendation that routine screenings for breast cancer should wait until your 50s rather than 40s? Math helps explain it.

In Our Mind's Eye
Here's an interesting approach to explaining the seeming complexity, order, and functionality of the universe: maybe it's all in our mind.
Psychologist Paul Bloom argues that we see intentional design and patterns too much... including in things that are actually random. So things that seem so fine-tuned and unlikely from our perspective might not actually be. Here's a video dialogue on this topic:
Bloom has two great books (Descartes' Baby and How Children Learn the Meaning of Words) on how our minds develop from early childhood on.

Blind Watchmaking
Here are some more critical links on the design argument for God's existence.
- Here is an audio interview on Hume's criticisms of the design arg.
- One philosophers' take on the debate between evolution and intelligent design.
- Is our universe fine-tuned for life? Maybe not.
- Wait, can science even judge religious claims, or are they talking about different things? Maybe an inference to the best explanation can help us...
- What about all the "design flaws" in nature? Are they evidence against a supreme designer?
- In the video below, astrophysicist Neil deGrasse Tyson points to all kinds of "stupid design" in the universe.

Reading Response #2
Reading Response #2 is due at the beginning of class on Wednesday, March 26th. The assignment is to write an approximately 500-word essay on
the following prompt:
What do you think best explains the seeming complexity, order, and functionality of natural objects and aspects of the universe? In other words, explain and evaluate the abductive version of the design argument for God's existence.The response is based on the design argument section of the textbook (chapters 5, 6, and 7--especially the abduction section on pages 55-57 and chapter 6 on evolution and creationism) and on the discussions we have in class, particularly on October 16th. Like the other reading responses, you won't be graded on your opinion. You'll be graded on how well you DEFEND your opinion. Reading response #2 is word 50 points (5% of your overall grade).
- First, briefly explain the abductive version of the design argument. Describe the relevant evidence that needs to be explained. List the possible hypotheses that attempt to explain that evidence. And explain why proponents of the design argument believe that the intelligent designer hypothesis is the most plausible one.
- Then, evaluate this argument. Is an intelligent designer the best explanation of this evidence? Or is another explanation better? Tell me your opinion. Do you think the abductive version of the design argument is a good argument or a bad argument? Why? Be sure to defend your opinion with reasons.

Like a Watch, Or an iPhone
Here are some links on the design argument for God's existence.
- Here is a nice explanation of the design argument, along with an explanation of a wild arg for god's existence that we're not studying.
- Here's an audio interview with Elliott Sober (the author of our textbook) on the design argument:
- Here's a long-ish video lecture on the notion of fine-tuning.

We're All Skeptics Now

Here are some links related to our discussion of René Descartes and skepticism from class.
Optical illusion time! Here is a pair of collections of Julian Beever's sidewalk art that looks three-dimensional when viewed from a certain angle. That's a picture of one of his creations above.
- The search for truth is tough. Let's get the FBI on the case!
- Here's an audio interview about Descartes's famous argument that he's certain he exists.
- Can we be abolutely certain of math claims like 2 + 3 = 5? This cartoon dinosaur says we can't.

By the way, if you have any links you think I or others in class might find interesting, let me know. And feel free to comment on any of these posts.

Reading Response #1: Descartes
Reading Response #1 is due at the beginning of class on Wednesday, February 19th Monday, February 24th. In about a 500-word essay, answer the following questions:
Please paraphrase Descartes's ideas in your own words. The response is based on the Descartes reading from pages 207-216 of the textbook.
- What kinds of beliefs does Descartes say he cannot be certain of? Why does he believe he can't be certain of these?
- Hint: Descartes mentions 2 general categories of beliefs in Meditation I (pages 207-210). See also pages 159-160.
- What beliefs does Descartes say he can be certain of? Why does he believe he can be certain of these?
- Hint: Descartes mentions 2 specific beliefs in Meditation II (pages 210-216). See also pages 160-162.
- Evaluate his reasons: do you agree with Descartes? Why or why not?

Murder on the Abductive Express
Here's a paper that explains the importance of considering and testing multiple possible explanations rather than a single hypothesis:
I think abductive reasoning is the most effective tool we have when faced with the myriad uncertain, ambiguous issues and decisions that everyday life throws our way.

An Argument's Support
One of the trickier concepts to understand in this course is the structure (or support) of an argument. This is a more detailed explanation of the term (it's the same as the handout). If you've been struggling to understand this term, the following might help you.
An argument's structure is its underlying logic; the way the premises and conclusion logically relate to one another. The structure of an argument is entirely separate from the actual meaning of the premises. For instance, the following three arguments, even though they're talking about different things, have the exact same structure:
1) All tigers have stripes.
Tony is a tiger.
Tony has stripes.
2) All humans have wings.
Sean is a human.
Sean has wings.
3) All blurgles have glorps.
Xerxon is a blurgle.
Xerxon has glorps.
There are, of course, other, non-structural differences in these three arguments. For instance, the tiger argument is overall good, since it has a good structure AND true premises. The human/wings argument is overall bad, since it has a false premise. And the blurgles argument is just crazy, since it uses made up words. Still, all three arguments have the same underlying structure (a good structure):
All A's have B's.
x is an A.
x has B's.
Evaluating the structure of an argument is tricky. Here's the main idea regarding what counts as a good structure: the premises provide us with enough information for us to figure out the conclusion from them. In other words, the premises, if they were true, would logically show us that the conclusion is true. So, if you believed the premises, they would convince you that the conclusion is worth believing, too.
Note I did NOT say that the premises are actually true in a good-structured argument. Structure is only about truth-preservation, not about whether the premises are actually true or false. What's "truth preservation" mean? Well, truth-preserving arguments are those whose structures are such that if you stick in true premises, you get a true conclusion.
The premises you've actually stuck into this particular structure could be good (true) or bad (false). That's what makes evaluating an arg's structure so weird. To check the structure, you have to ignore what you actually know about the premises being true or false.
Good Structured Deductive Arguments (Valid)
If we assume that all the premises are true, then the conclusion must also be true for a deductive argument to have a good structure (to be valid). Notice we are only assuming the truth of the premises, not guaranteeing it. Again, this makes sense, because we’re truth-preservers: if the premises are true, the conclusion that follows will be true.
EXAMPLES:
1) All humans are mammals.
All mammals have hair.
All humans have hair.
2) If it snows, then it’s below 32 degrees.
It is snowing right now.
It’s below 32 degrees right now.
3) All humans are mammals.
All mammals have wings.
All humans have wings.
4) Either Yao is tall or Spud is tall.
Yao is not tall.
Therefore, Spud is tall.
Even though arguments 3 and 4 are ultimately bad, they still have good structure (their underlying form is good). The second premise of argument 3 is false—not all mammals have wings—but it has the same exact structure of argument 1—a good structure. Same with argument 4: the second premise is false (Yao Ming is about 7 feet tall), but the structure is good (it’s either this or that; it’s not this; therefore, it’s that).
To evaluate the structure, then, assume that all the premises are true. Imagine a world in which all the premises are true. In that world, are you able to figure out from the premises that the conclusion is also true? Or can you imagine a scenario in that world in which the premises are true, but the conclusion is still false? If you can imagine this situation, then the argument's structure is bad. If you cannot, then the argument is truth-preserving (inputting truths gives you a true output), and thus the structure is good.
Bad Structured Deductive Arguments (Invalid)
An invalid deductive argument has a bad structure. You can’t draw the conclusion from the premises – the premises don’t give you enough information. Bad structured arguments do not preserve truth.
EXAMPLES:
1) All humans are mammals.
All whales are mammals.
All humans are whales.
2) If it snows, then it’s below 32 degrees.
It doesn’t snow.
It’s not below 32 degrees.
3) All humans are mammals.
All students in our class are mammals.
All students in our class are humans.
4) Either Yao is tall or Spud is short.
Yao is tall.
Spud is short.
Even though arguments 3 and 4 have all true premises and a true conclusion, they are still have a bad structure, because their form is bad. Argument 3 has the same exact structure as argument 1—a bad structure (it doesn’t preserve truth).
Even though in the real world the premises and conclusion of argument 3 are true, we can imagine a world in which all the premises of argument 3 are true, yet the conclusion is false. For instance, imagine that our school starts letting dogs take classes. The second premise would still be true, but the conclusion would then be false.
The same goes for argument 4: even though Spud is short (Spud Webb is around 5 feet tall), this argument doesn’t guarantee this. The structure is bad (it’s either this or that; it’s this; therefore, it’s that, too.). We can imagine a world in which Yao is tall, the first premise is true, and yet Spud is tall, too.

Students are cringing right now.
Sean is singing right now.
P1- questionable (again, you don't know)
P2- false
structure- invalid (from premise 1, we only know that Sean singing is one way to guarantee that students cringe; just because they're cringing doesn't mean Sean's the one who caused it; again, students could cringe for a different reason)
overall- unsound (untrue premises and bad support)
14) If Sean sings, then students cringe.
Students aren't cringing right now.
Sean isn't singing right now.
Students aren't cringing right now.
Sean isn't singing right now.
P1- questionable (again, you don't know)
P2- true
structure- valid (the premises say Sean singing guarantees that students cringe; since we know students aren't cringing, we know Sean can't be singing)
overall- unsound (untrue 1st premise)
15) All students in here are humans.
Most humans are shorter than 7 feet tall.
Most students in here are shorter than 7 feet tall.
Most humans are shorter than 7 feet tall.
Most students in here are shorter than 7 feet tall.
P1- true
P2- true!
support- invalid (the premises state a strong statistical generalization over a large population, and the conclusion claims that this generalization holds for a much smaller portion of that population; while it could be true that the humans in here are a statistical anomaly, given the strength of the generalization, it's likely that most students in here are, in fact, shorter than 7 feet tall)
overall- unsound (not perfect, since the support isn't perfect, but pretty good)
16) If there is no God, then life is meaningless.
Life isn't meaningless.
There is a God.
Life isn't meaningless.
There is a God.
P1- questionable (that's not an obvious claim)
P2- questionable (again, that's not an obvious claim)
support- valid (the same structure as argument #13)
overall- unsound (untrue premises)

Philosophers In Their Own Words
Photographer Steve Pyke has a cool series of portraits of philosophers.
Many of the philosophers also provide a short explanation of their
understanding of what it is they do. Here are a few of my favorites:
Delia Graff Fara:
Sally Haslanger (only available in the book):

"By doing philosophy we can discover eternal and mind independent truths about the ’real’ nature of the world by investigating our own conceptions of it, and by subjecting our most commonly or firmly held beliefs to what would otherwise be perversely strict scrutiny."
"Philosophy is the strangest of subjects: it aims at rigour and yet is unable to establish any results; it attempts to deal with the most profound questions and yet constantly finds itself preoccupied with the trivialities of language; and it claims to be of great relevance to rational enquiry and the conduct of our life and yet is almost completely ignored. But perhaps what is strangest of all is the passion and intensity with which it is pursued by those who have fallen in its grip."

"Given the amount of suffering and injustice in the world, I flip-flop between thinking that doing philosophy is a complete luxury and that it is an absolute necessity. The idea that it is something in between strikes me as a dodge. So I do it in the hope that it is a contribution, and with the fear that I’m just being self-indulgent. I suppose these are the moral risks life is made of."

Homework: Email Subscription
So why does this course have a blog? Well, why is anything anything?
A blog is a website that works like a journal – users write posts that are sorted by date based on when they were written. You can find important course information (like assignments, due dates, reading schedules, etc.) on the blog. I’ll also be updating the blog throughout the semester, posting interesting items related to the stuff we’re currently discussing in class. You don't have to visit the blog if you don't want to. It's just a helpful resource. I've used a blog for this course a lot, and it's seemed helpful. Hopefully it can benefit our course, too.
Since I’ll be updating the blog a lot throughout the semester, you should check it frequently. There are, however, some convenient ways to do this without simply going to the blog each day. The best way to do this is by getting an email subscription, so any new blog post I write automatically gets emailed to you. (You can also subscribe to the rss feed, if you know what that means.) To get an email subscription:
1. Go to http://2014rowanphilosophy.blogspot.com.
2. At the main page, enter your email address at the top of the right column (under “EMAIL SUBSCRIPTION: Enter your Email”) and click the "Subscribe me!" button.
3. This will take you to a new page. Follow the directions under #2, where it says “To help stop spam, please type the text here that you see in the image below. Visually impaired or blind users should contact support by email.” Once you type the text, click the "Subscribe me!" button again.
4. You'll then get an email regarding the blog subscription. (Check your spam folder if you haven’t received an email after a day.) You have to confirm your registration. Do so by clicking on the "Click here to activate your account" link in the email you receive.
5. This will bring you to a page that says "Your subscription is confirmed!" Now you're subscribed.
If you are unsure whether you've subscribed, ask me (609-980-8367; landis@rowan.edu). I can check who's subscribed and who hasn't.

Required Texts
Core Questions in Philosophy, 5th Edition, by Elliott Sober
About the Course
This course is designed to introduce students to philosophy. Throughout the semester, we will explore a handful of classic philosophical questions: What is knowledge, and what can we know? What evidence is there regarding the existence of a God? What is the relationship between the mind and the body? Do humans have free will?
We will also be developing various philosophical skills, including:
- Understanding: the ability to identify and explain an author’s main point in your own words, along with the ability to identify and explain an author’s argument in support of this main point.
- Evaluating: the ability to critically and charitably determine whether these arguments provide accurate, logical reasons in support of their main points, along with the ability to engage in critical and charitable dialogue with people who hold different views from your own.
- Defending: the ability to develop your own arguments in support of your opinions on the ethical issues we study, along with the ability to honestly assess your opinions and critically evaluate the quality of your arguments in support of them.
Assignments
Each assignment is created carefully, and designed to both measure and improve upon specific skills that students are expected to develop throughout the semester. I try to explicitly point out the educational importance of each assignment (both below and when I assign it), but if an assignment’s value is ever unclear, let me know! I value student feedback. Sometimes complacency makes me continue using an assignment that isn’t very helpful, or sometimes I haven’t explained an assignment clearly enough.
Tests: There will be three tests, each one worth more points than the last. Tests are a chance to demonstrate your understanding of a wide variety of topics and skills that we’ll study throughout the semester. To this end, there will be a variety of question types on the exams. Test #1 will be on the logic and knowledge sections of the course. Test #1 will last about 25 minutes, and be held at the beginning of class on the scheduled day. Test #2 will be on everything covered during the first half of the course, and will last the first half of class (80 minutes) on the scheduled day. Test #3 is cumulative—that is, it will be on everything covered throughout the whole course. Test #3 will also last 80 minutes, and will take place during finals week.
Reading Responses: There will be four reading responses, which are to be handed in at the beginning of class the day they are due. Each assignment is an approximately 500-word essay response to a specific question about one or more of the week’s readings. The responses are a chance to do philosophy. To this effect, the focus of the responses will be on paraphrasing (demonstrating that you understand the reading by explaining it in your own words) and critically evaluating (presenting objections to the argument in the reading, or responding to such objections) the philosophical arguments being presented in the readings.
Fun Wednesdays: There will be 3 in-class graded assignments scheduled on some Wednesdays during the semester. These will be a chance to more casually discuss some issues more loosely related to the class, yet more closely connected to important practical concerns of our everyday lives.
Attendance/Participation: Most of this will be based on your attendance. If you’re there every class, you’ll get full credit for your attendance grade. In addition, there will be a lot of informal group work throughout the semester in which students get together to analyze the readings or philosophical issues being discussed in class. Group work can impact this grade. I value your attendance, and I expect you to show up each day. I also realize, though, that we sometimes need added motivation to attend each day, and I use this grade as a small carrot to motivate you.
Extra Credit: I like giving extra credit! I’ll be giving some official extra credit assignments throughout the semester. I’ll also be offering some extra credit points more informally during class time. Remind me about this if I slack off on dishing out extra credit points.

Classroom Policies
Academic Integrity: Cheating and plagiarism (using someone else’s words or ideas in a paper or assignment without giving credit to the source) will not be tolerated in the class. Students found guilty of either will definitely fail the exam or assignment on which they plagiarize—and possibly the entire class. FYI: I’m pretty good at catching plagiarists. I recommend not trying it!
Excused Absences: Any assignment will only be rescheduled for an excused absence. Excused absences include religious observance, official college business, and illness or injury (with a doctor’s note). An unexcused absence on the day of any assignment or test will result in a zero on that assignment or test.

Disability Accommodations: If you have special requirements let me know as soon as possible so we can make all necessary arrangements.
Expectations
Philosophy can be a difficult subject to master. I expect each student to put in a lot of effort on a variety of fronts.
Read the Textbook. The textbook is, in my opinion, well written, full of insights, and quite helpful. Still, the assigned readings are often dense. This means that you may not fully understand what you read the first time you read it. Do not despair; this is common. Philosophical writings are best understood upon multiple readings. You should develop the habit of reading the assigned pages a few times, including both before and after our class discussion of the relevant material.
Attend Class. While the book is informative, often time the assigned reading is only a launch pad, and the key skills or concepts we’re learning during a given section goes beyond the book. If you can’t attend class one day, that’s unfortunate, but OK (and outside excused absences, you need not tell me why—frankly, I don’t care why you’re not there). But don’t make a habit of missing classes.
Participate in Class. Our classroom is a judgment-free zone. I’m not concerned with students acting perfectly or seeming smart during class. In fact, effective learning involves discussing precisely the things we don’t fully understand yet. Learning is a process that involves lots of failing: getting it wrong, figuring out where we went wrong, and trying again. Lots of class time will involve this type of (helpful) failing. This goes against how many of your classes are run. Good. I think many assumptions in our current education institutions aren’t conducive to effective learning. In class we’ll engage in helpful discussions. If something confuses you, let me know! Chances are, it confuses other students, too. Sometimes, I think I’ve understood something I read, only to discover upon discussing it that I haven’t really grasped it. Getting feedback from a group of smart people who’ve read the same thing as you is invaluable to learning. I understand some students are shy (I was shy myself in college), but try not to be timid simply out of fear of looking silly or stupid.
Practice. In addition to guided discussions, class time will involve a lot of informal group work on philosophical problems. There will also be lots of optional extra credit assignments. These are chances to practice. We are mostly developing skills in this class, skills that cannot be picked up in five minutes. Skills take prolonged training and effort, like learning to play the piano or hitting a 90-mph fastball. Again, be OK with failing! Just try to fail better each time you practice.
Because of this, I try to measure students based on the progress they make throughout the course. A student who struggles early in the semester is not doomed to a low grade. Early struggles are merely a warning sign that more or a different kind of effort is required. On the other end of the spectrum, for a small percentage of students, getting a good grade in this class will be relatively easy. For such students, I encourage you to challenge yourself. Don’t settle for merely learning the most basic skills we’re studying. Try to develop the more advanced skills touched on throughout the course. Read the articles linked to on the course blog! Talk to me outside class! Commit yourself to taking full advantage of this class.
Care About Learning. This should be your primary goal of taking this class—not getting a good grade, or socializing, or impressing me, or whatever. While I understand that these other things are important (I care a lot about the social value of college, for instance), these should not supersede your devotion to learning.
