Faith & Reason: Strange Bedfellows?

For more on today's presentation:

• "The Ethics of Belief," William Clifford's classic argument for evidentialism
  
• "The Will to Believe," William James's nonevidentialist response to Clifford
  
• "Believing Without Evidence," a modern-day evidentialist's take on the Clifford-James debate

Midterm

Just a reminder: the midterm will be held on Friday, November 5th. It's worth 20% of your overall grade. There will be a review in class on Wednesday. It will cover the topics we discussed in class so far:

• philosophy in general
• doing philosophy
• understanding and evaluating arguments
• types of arguments: deductive, example, analogy, causal, authority
  
• what is knowledge?
• Plato on knowledge vs. true belief
  
• skepticism (specifically external world skepticism)
  
• Descartes battling skepticism
• Descartes's certainty: his arg that "I exist"
  
• Nick Bostrom's simulation arg for skepticism
• God stuff
• The cosmological argument, specifically:
• Aquinas's "first cause" version of the argument
  
• The abductive version of the "first cause" argument
  
• Aquinas's "contingency" version of the argument
  

BE THERE.

Virtual Dinosaurs

Here's a more advanced version of the Nick Bostrom article we've discussed in class about the potentially high probability that we're actually living in a Matrix-like virtual reality. If you get really into Bostrom's argument, there's a whole website devoted to debating it (including a FAQ written by Bostrom).

Of course, T-Rex has read this article, too:

I'm Certain I'm Doubting

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.

Skepticism and Other -isms

If you're looking for more stuff on external world skepticism for the first paper assignment, this entry on skepticism might be helpful. It's a bit more accessible than other entries in the Stanford Encyclopedia of Philosophy, and it includes several attempts to combat arguments for skepticism, including the fallibilist and contextualist strategies we discussed in class.

We're All Skeptics Now

Here are some links related to our discussion of knowledge and skepticism from class.

• What are the philosophical implications of the movie The Matrix?
  
• Here's a summary of a cool argument (pdf) for an interesting version of skepticism I call "unsettled debate" skepticism. There's also an entire book on it.
  
• I recently interviewed the author of that book for the Owning Our Ignorance club. Here's the audio interview.

New Due Date: at the beginning of class on Wednesday, October 13th, 2010 Wednesday, October 20th, 2010

Worth: 50 points (5% of final grade)

Assignment: Write an argumentative essay on external world skepticism: the claim that we do not know anything about the physical world beyond our immediate sense experiences. In particular, choose one of the topics below. Papers must be typed, and must be between 300-600 words long. Write down the word count on the first page of the paper.

Possible Paper Topics
1. Criticize skepticism of the external world. Describe what you take to be the best argument for external-world skepticism. Then evaluate this argument. Exactly how is this argument bad? Be specific: what is/are its flaw(s)? How can we avoid giving in to the skeptic’s arguments that we don’t know anything about the world?
[NOTE: For this option, you don’t have to present a positive argument for the existence of the external world. Just explain why the skeptical argument you focus on is bad.]

2. Tell me why you’re not a skeptic: Present and defend an argument for the claim that we can know that there is an external world beyond our sense experiences. Be sure to consider and respond to objections to your argument that a skeptic would likely offer.

3. Defend external-world skepticism. Present an argument for external-world skepticism. Then consider and respond to objections to this argument. Pay special attention to your conception of knowledge: defend the conditions you believe are required for knowledge.

4. Explain and evaluate Nick Bostrom’s argument in “Do We Live in a Computer Simulation?” Do you think Bostrom makes a good case for external-world skepticism? Why or why not? Be sure to fully explain your evaluation of his argument, and defend your opinion.

5. Write something else on skepticism. (Sean must approve this topic by Wednesday, October 6th.)

Am I a Jerk Because I Annoy You, or Do I Annoy You Because I'm a Jerk?

Socrates has a reputation of being a bit of a jerk. The following robot reenactment of one of his dialogues does little to dispel this reputation:

K = JTB?

I wonder whether Plato would agree with T-Rex's analysis of knowledge:


In panel 5, Utahraptor is bringing up a Gettier case counterexample to the claim that knowledge = justified true belief. If you're looking for FUN TIMES, ask me about the Gettier problem in class!
