Confusing Levels of Explanation


I read an article in Scientific American Mind about homosexual behavior in animals. Turns out over 1500 species have been observed doing it. Scientists have theories of why this is. The article states "Researchers are now revealing, for example, that animals may engage in same-sex couplings to diffuse social tensions, to better protect their young or to maintain fecundity when opposite-sex partners are unavailable--or simply because it is fun."  I'm afraid I must quibble with this last bit, because it's mixing levels of explanation. 

I'm sure animals almost always engage in sexual activity because it's fun. Now, the reason there is a sex drive at all is because of, in part at least, pregnancy. But that does not mean that an individual animal engages in sex because he or she wants a pregnancy. This is especially true for non-human animals. 

The reason an organism does something and the reason that organism has the drive to do something are different questions with different kinds of answers. For example, I eat because I am hungry, or because I want to taste the food I'm eating. The reason I have hunger is so that I eat, so I will get the nutrients I need to live. 

The genes are a blueprint for a being with drives. The drives are there because they propagate the genes. That is their teleological function. But the day-by-day decisions of beings are for goals and reasons that have to do with their drives, personal history, and immediate environment.

The difference is crucial, and there are several excellent books that explore the ramifications: Dawkins (1979), and Stanovich (2004).

New Year's Resolution 2009: No eating... cold turkey

Every year my man Lou Fasulo and I do some crazy new year's resolution. Last year we drank no soda (pop for my Canadian readers).  

http://jimdavies.blogspot.com/search?q=new+year's+resolution

In general it was a successful year for me. I only had one screw up. It was in London, when I was visiting my girlfriend. I was thirsty and bought some damn thing that looked like juice or flavoured water. I swallowed a sip before I realized it was carbonated. The funny thing is this is exactly how I screwed up the one time I did 20 years ago, the last time I gave up soda for the year. 

Anyway, now I'm drinking Cherry Coke and Pepsi again and I have to say it tastes glorious. If you take soda for granted, try giving it up for a few months. You'll find it tastes better than much of the food you eat with it.

This year we're giving up eating cold turkey. We can eat hot turkey. If we have cold turkey, we can heat it up and eat it, but not after it cools. So if I get a turkey sub at Quizno's, I have to toast it and eat it while it's hot. 

Granted, this one won't be particularly challenging. But it's our 21st year doing it; we're through testing our willpower. Now we're looking for ones we find interesting. This one's interesting to me because when I describe it to people in person it sounds at first like I'm giving up eating.

Drawing With A Single Line


My drawing style is usually cartoonish and constrained. I'm trying to break out of that, and one way I do that is to sketch while keeping the pen on the paper and not take it off. I like how it ends up. The content is still recognizably mine (to me anyway) but I like trying to break out of my normally-constrained style. Here are two recent sketches. The majority of them are made without lifting the pen, and then some final decoration is done relaxing this constraint.
