Why I [believe/don’t believe] in God

Andrew Zak Williams asks 30 believers and 30 non-believers why. Their answers do a great job summarizing the major arguments and philosophies of both camps.

Theists assert a number of reasons for their belief: their need for there to be some purpose in the world rather than see the universe as the result of the unguided vagaries of random chance; profound, spiritual experiences in their past; their perception that the beauty of life and the universe must have had some (intelligent) design; and sometimes, an acknowledgment of the need for an element of blind faith.

Atheists, on the other hand, argue the lack of evidence; the often prejudicial, unjust nature of the religions many of them grew up with; and the fact that to recognize one type of religion as correct, often requires its adherents to believe that the others are wrong, leading to the conjecture that none of them are right and they’re all wrong.

Stephen Hawking tries to thread and interesting needle:

I am not claiming there is no God. The scientific account is complete, but it does not predict human behaviour, because there are too many equations to solve.One therefore uses a different model, which can include free will and God.

— Stephen Hawking (2011) in Faith no more (Williams, 2011) in the NewStatesman.

Many adolescents will be encountering these types of questions on their own or through all the bat mitzvah, confirmations and other religious coming-of-age ceremonies adolescents face. Either one of these two articles would be an interesting, if delicate, subject for a Socratic dialogue, especially while studying the history of religions.

Parting the Red Sea: Biblical Scenes from Space and Computer Modeling on the Earth

The Glue Society has a most interesting set of satellite images modified to look like major biblical scenes. CreativeReview has more pictures and details, including of the crucifixion and Noah’s Ark.

“We like to disorientate audiences a little with all our work. And with this piece we felt technology now allows events which may or may not have happened to be visualized and made to appear dramatically real,” say The Glue Society’s James Dive. “As a method of representation satellite photography is so trusted, it has been interesting to mess with that trust.”

I think this topic came up when we were talking about atmospheric circulation. The question was about if the winds generated descending, diverging air could have parted the Red Sea. The answer was no, because the general atmospheric circulation system is a thing of climate — averages of the weather — while any winds strong enough to part the red sea would be actual weather, like the storms we seem to have been seeing every day for the last few weeks.

Oddly enough, just last year researchers from the University Corporation for Atmospheric Research (UCAR) did a computer model that showed that hurricane force winds from the northwest could have uncovered an underwater reef to allow Moses his passage (the article is Drews and Han, 2010).

However, the scientists found:

[The] reef would have had to be entirely flat for the water to drain off in 12 hours. A more realistic reef with lower and deeper sections would have retained channels that would have been difficult to wade through. In addition, Drews and Han were skeptical that refugees could have crossed during nearly hurricane-force winds.

NPR’s article on the topic is worth a listen.

Looking up the definition of a “soul”

Our funeral pyre has sparked at least one argument about what is the soul. Now they’re looking up the definition of “immaterial”. They’re also trying to decide if all living things have a soul, including, for some reason, the dried basil, hanging from the window. Success!

What’s the difference between humans and animals?

In the field of cognition, the march towards continuity between human and animal has been inexorable — one misconduct case won’t make a difference. True, humanity never runs out of claims of what sets it apart, but it is a rare uniqueness claim that holds up for over a decade. This is why we don’t hear anymore that only humans make tools, imitate, think ahead, have culture, are self-aware, or adopt another’s point of view. – Frans De Waal (2010).

My students studied the question, what is life, last cycle, and through their readings and Socratic dialogue I’ve been trying to approach the question of what is sentience and what distinguishes humanity from other organisms (or robots for that matter).

We’ve found that the lines between us and them are very hard to draw.

Pushing the discussion into questions of morality, primatologist Frans De Waal has a wonderful post on where it comes from, and if there is any clear distinction between humans and other animals. He argues that morality is innate, a product of evolution, and there aren’t clear distinctions.

The full article is a worthy read, with good writing and well constructed arguments. It’s a bit too long for a Socratic Dialogue but might be of interest to the more advanced student, particularly those going through religious, coming-of-age, rites of passage, like preparations for confirmations and Bar Mitzvahs. While De Waal’s evolutionary reasoning has been used to argue against religion, he takes a much more subtle approach:

Our societies are steeped in it: everything we have accomplished over the centuries, even science, developed either hand in hand with or in opposition to religion, but never separately. It is impossible to know what morality would look like without religion. It would require a visit to a human culture that is not now and never was religious. That such cultures do not exist should give us pause. – Frans De Waal (2010).

We have fish!

While we were working on the needs of living things a couple weeks ago, we acquired two fish; goldfish, fifteen cents apiece.

It was supposed to only be a mental exercise. If you put a water plant, Egeria densa in this case, in an enclosed jar and left it in the sunlight, the plant should use the carbon dioxide in the water to produce oxygen during photosynthesis. A similar jar kept in the dark would produce carbon dioxide and use oxygen as the plant respired.

That was the practical part. Students measure the pH of the water before and after a day in the light and dark. The pH of the jar in the dark should go down as the added carbon dioxide makes the water slightly more acidic. Bromthymol blue solution in the water changes color very nicely within the pH range of this experiment, but, in a pinch, you can also use the pH color strips that are sold for testing aquarium water.

My students did the experiment, made their observations and came to conclusions. Then the lab activity asked them to think about what would happen if you put a fish into each of the jars, to see if students are able to extrapolate based on a well rounded knowledge of respiration and photosynthesis.

My students did the mental experiment, but the next day our two fish turned up, uninvited at least by me.

I’d anticipated something like this so I’d picked up a small fish tank at a yard sale over the summer. I’m not opposed to keeping animals in the classroom, as long as I don’t have to take care of them. Fortunately, since we’re studying life, keeping organisms and attending their needs is something the kids are learning and there is no better way to learn that via practice.

Our fish are surviving. The students have added some gravel and structures to provide habitat. The waterplants, still in there to provide oxygen, seem to be thriving despite some browsing by the goldfish.

One of the few rules is that anything added to the tank should have some purpose to help support the needs of the fish. I’m also encouraging the students to think of ways of maintaining conditions in the tank which would minimize their work. Hopefully some filter feeders, maybe small clams, and similar organisms will turn up and we can talk about ecology. I may have to nudge them in that direction though.

I’m not sure what the fish’s names are as there seems to be some controversy among the students. With a little luck they’ll survive until we start comparing religions. Two years ago we had a frog who passed away at just the right time for us to have to figure out what religion he/she was so we could perform last rites.

And no, I did not kill the frog.
