Goodbye to Yesterday...

Your grades are now posted. Enjoy your winter break!

I'll leave you with a little rant on that favorite topic of mine: intellectual honesty. A simple goal of this class was to get us all to recognize what counts as good evidence and what counts as bad evidence for a claim. I think we did get better at that. But this doesn't guarantee that we'll care about the difference once we figure it out.

Getting us to care was the real goal of this class. We should care about good evidence. We should care about evidence and arguments because they get us closer to the truth. When we judge an argument to be overall good, THE POWER OF LOGIC COMPELS US to believe the conclusion. If we are presented with decent evidence for some claim, but still stubbornly disagree with this claim, we are just being irrational. Worse, we're effectively saying that the truth doesn't matter to us.

Instead, we should be open-minded. We should be willing to challenge ourselves, and let new evidence change our current beliefs. We should be open to the possibility that we've currently gotten something wrong. This is how comedian Todd Glass puts it:


Here are the first two paragraphs of a great article I read last year on this:

Certainty Is a Sign of IgnoranceLast week, I jokingly asked a health club acquaintance whether he would change his mind about his choice for president if presented with sufficient facts that contradicted his present beliefs. He responded with utter confidence. "Absolutely not," he said. "No new facts will change my mind because I know that these facts are correct."

I was floored. In his brief rebuttal, he blindly demonstrated overconfidence in his own ideas and the inability to consider how new facts might alter a presently cherished opinion. Worse, he seemed unaware of how irrational his response might appear to others. It's clear, I thought, that carefully constructed arguments and presentation of irrefutable evidence will not change this man's mind.

Ironically, having extreme confidence in oneself is often a sign of ignorance. In many cases, such stubborn certainty is unwarranted.

If any of this sounds cool to you, consider joining the "Owning Our Ignorance" club I run. (We even have a Facebook group!)

Just a reminder: the final exam is Thursday, December 17th at 6:00 in our normal classroom. It should take about 90 minutes to finish it, but you'll have two hours to take it.

OK, One: Napping

Hear No Evil

If you like to get philosophical on the treadmill, try downloading and listening to these podcasts on the problem of evil:

Her Stroke of Insight

This is indirectly related to what we're discussing in class. It shows the degree to which our mind actively constructs our understanding of reality around us. Here's neuroscientist Jill Bolte Taylor's TED talk on her experience of having a stroke:


Bolte Taylor wrote a whole book on her experience. It's available in most book stores. Here's a more detailed audio interview with her.

I love TED talks. Here are some of my other favorites:

Design in the 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.
