Join the Club!

Still subscribed to this old course blog? Nice.

So, I'm trying to start up a school club -- the "Owning Our Ignorance" club -- devoted to fun and logic, in that order. I've put up a blog for it over here.

Check it out. Please join if you're interested.

Reading Response #4

Here is the assignment for the final reading response of the semester. Sadz.
Do you think morality involves universal rules that apply in all circumstances with no exceptions? Or do you think circumstances are relevant to judging the morality of a particular action? Be sure to explain and philosophically defend your answer.
The response is due Monday, April 30th for the Monday night class, and Tuesday, May 1st for the Tuesday & Thursday classes.

Links Worthy of a Swine

Here are some links that are very loosely related to the stuff on Utilitarianism that we are studying. Most of these deal with psychology. There's a lot of psychological research on happiness popping up lately. The first link is an overview of the psychology of happiness:

The second is a slightly optimistic take on our ability to change our baseline level of happiness. This is important to know for an ethical theory that values maximizing happiness:


The next link deals with a famous moral thought experiment, the trolley problem. This gets brought up a lot when evaluating Utilitarianism:


The last link is an advanced overview of "consequentialist" ethical theories. Utilitarianism is one of the most well-known consequentialist theories:


So what makes you happy? Ping pong? WaWa? Coldplay?

Relative to You, But Not to Me

Here's a trio of links on ethical relativism. The first is a sophisticated version of ethical relativism backed up by recent psychological research.

The second one is an advanced overview of various versions of moral relativism from a great online resource.


The last one is a dinosaur comic (what else?) on ethical relativism. Click on the comic to enlarge it:

I'm, uh, paid by the word

Extra Credit Assignment

As we discussed in class, here is an optional extra credit assignment.
In an essay that's as long as a reading response, answer the following questions: Which do you think is more important to determining the morality of a particular action: the intentions behind someone's actions, or the consequences of that action? Why do you think this? Be sure to explain and philosophically defend your position.
For the Monday night class, this assignment is due Monday, April 23rd. For the Tuesday/Thurdsay classes, this assignment is due Tuesday, April 24th. It is worth up to 2.5 points added to your final grade. I will not accept any late assignments (unless you have an excused absence).

Reading Response #3

Here is the assignment for reading response #3. For the Tuesday/Thursday classes, it is due Tuesday, April 10th. For the Monday night class, it is due Monday, April 16th.
Explain and philosophically defend your beliefs about the existence of God. Are you a theist? Atheist? Agnostic? Are you a non-evidentialist? What reasons do you have for your position? Has your position changed at all as a result of studying arguments for and against the existence of God in this class? Have the reasons you use to support your beliefs changed?

Faith + Reason = Terry Gross

The National Public Radio show Fresh Air just ran a pair of interviews with two scientists talking about whether God exists. The conversations touch on a lot of things we've been discussing in class.
Hey, where's the interview with an agnostic? The media are so biased toward those with opinions.

Review: Deductive Soundness

DEFINED: A deductive argument is sound when:
(1) the argument is valid; and
(2) all the premises are true.

WHAT IT MEANS: This is the gold standard—as good as it gets for a deductive argument. From the start, a sound argument has to be valid. But on top of it, each premise must also be true.

So to test for soundness, we first do our validity test. We do the imagine-a-world test. If the arg fails this test, then it's invalid, and automatically unsound.

If it passes the validity test, then we need to check the actual truth of the premises. So we forget about the imaginary world, and come back to the real world. Are all of the premises actually true in the real world, or is one or more false or questionable (opinionated)? If they're all true, then the argument is sound. If one or more is false or questionable, then the argument is unsound.

An argument is unsound if it is not sound. (duh) But remember, it’s easy for an argument to be unsound. Only one of many things has to go wrong for an argument to be unsound. One false premise, and it’s unsound. One false move in an argument that makes it invalid, and it’s unsound.

Review: Deductive Invalidity

DEFINITION: A deductive argument is invalid when the truth of the premises does NOT guarantee the truth of the conclusion.

WHAT IT MEANS: If an argument isn’t valid, it is invalid. This means that you can’t draw the conclusion from the premises – they don’t naturally follow. Invalid 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 BCC students are mammals.
All BCC students 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 invalid, 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 BCC starts letting whales take classes. The second premise would still be true, but the conclusion would then be false.

The same 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.

Review: Deductive Validity

Here's a review of the tricky term "valid" as it refers to deductive arguments:

DEFINED: A deductive argument is valid when the truth of the premises guarantees the truth of the conclusion.

WHAT IT MEANS: Validity focuses on the form or structure of the argument. If an argument is valid, then it has good form – truth preserving form.

Basically, if we assume that all the premises are true, then the conclusion must also be true for an argument to be valid. Notice we are only assuming the truth of the premises, not checking to see whether they are actually true. Again, this makes sense, because we’re truth-preservers: if the premises are true, the conclusion that follows must 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 snows.
It’s below 32 degrees.

(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 are still valid—their 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 valid 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 validity, then, assume that all the premises are true. Imagine a world in which all the premises are true. In that world, MUST the conclusion also be 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 is not valid. If you cannot, then the argument is truth-preserving (inputting truths guarantees a true output), and thus valid.

IMPORTANT: Individual sentences are true or false. Arguments are valid or invalid.

Links to God

Courtesy of Barry from the 3:30 Tuesday/Thursday class, here's yet another comic on the ontological argument.

There are also two articles on the psychology of religious beliefs that are somewhat relevant to what we're going over in class. Here is a very recent New York Times Magazine article, and here is a similar but older Atlantic Monthly article.

Finally, here is a short criticism of the design argument for God's existence, again from the New York Times Magazine.

Intelligent design is a hot topic in the mainstream media. If you've read a good article on the subject, recommend it to us by emailing me or posting the link in the comments section of this post.

Think [Tap-Dance] God

There's a philosophy comic strip that is running a whole series on the ontological argument that god exists. Here are the comics:




If you're still jonesing for the a priori, there's also this entry on ontological arguments in the Stanford Encyclopedia of Philosophy.

Reading Response #2

Reading Response #2 is due Monday, March 12th (for the Monday night class) or Thursday, March 15th (for the Tuesday/Thursday classes). The assignment is to write a 250- to 500-word essay in which you address the following:
Explain what you think the best version of the cosmological argument is. Then philosophically evaluate this version.
As a reminder, we have already discussed three different versions of the cosmological argument in class: (1) Thomas Aquinas's "first cause" version, (2) an abductive (inference to the best explanation) version, and (3) Richard Taylor's version. Aquinas's and Taylor's versions are in the textbook, but we only talked about the abductive version in class.

Innate Ideas: I've Had a Few

Here are a couple articles by Steven Pinker that offer some psychological insights on the innate ideas debate we discussed in class:

But hey, why read when you can watch a video? With that in mind, here's his appearance on The Colbert Report (the second part is particularly relevant to innate ideas):




Pinker has a few books on this stuff, and a lot of other interesting articles, too.

So Important They Give It Away

The week of February 19th-23rd we'll be going over the debate in epistemology between rationalists and empiricists. Here's an advanced survey article on the debate from my favorite free online philosophy encyclopedia:

Yes, there is more than one free online philosophy encyclopedia.

The Antidote to Humeanism

Do you find yourself obsessed with Hume's question of what could justify inductive reasoning? Boy, do I have a link for you:


Or, you could watch a dog puppet insult people waiting in line to see Star Wars:


Hmmm... is Triumph justified in concluding that all Stars Wars fans are nerds?

3:30 Class: Room Change

To all the students in the 3:30-4:50 Tuesday/Thursday Philosophy class: we're changing classrooms.

Beginning this Thursday, class will be held in Room 112 of the Technology & Engineering Center (TEC). We'll be having class there for the rest of the semester.

TEC is right next to Laurel Hall at the Mt. Laurel Campus. Here's a map (click on it to enlarge):

NJ = OH Amplified?

Perhaps this is why my vacation to Ohio wasn't that exciting:
John Gorka - I'm From New Jersey
"I'm from New Jersey | It's like Ohio | But even more so | Imagine that"
NJ Historian/Clean Hippy
The"more so" comparison is also used in the design argument for God's existence. We'll be discussing that later on this semester.

Oops. Sorry for turning this into a post about philosophy.

Reading Response #1

The first reading response is due Thursday, February 8th (if you're in a Tuesday/Thursday class) or Monday, February 5th (if you're in the Monday night Holy Cross class). In a 250- to 500-word response, you are to answer the following question:
What does Descartes say he cannot be certain of? What does Descartes say he can be certain of? Do you agree with Descartes? Why or why not?

The response is based on the reading from pages 58-71 of the textbook.

Link Tested, Keanu-Approved

Here's a trio of links. The first one is a guide to reading philosophy that might help you if you're having trouble understanding the assigned readings.

Jim Pryor's Guide to Reading Philosophy

The next two relate to epistemology and skepticism, which are what we'll be talking about starting with the Descartes reading. Both are about the movie The Matrix. The first is pretty straightforward (If Neo read it, he'd say 'whoa'), but the second is a little more advanced (If Neo read it, he'd say 'huh?').

The Matrix: Dream Skepticism
u just bl3w my mind, dudeThe Matrix: Brain-in-a-Vat Skepticism

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.
