Wonderful Life

I finally slogged my way through the last of what is certainly a very worthy text on the Burgess Shale, the Cambrian Explosion, and the proper way to understand contingency in evolution, by Stephen Jay Gould titled "Wonderful Life". Yes, the title pays homage to the Frank Kapra movie "It's a Wonderful Life" because the angel shows Jimmy Stewart's (George Baily) what the town would be like if he had never been born. Gould attempts a bit of that conjecture, but mostly he just points out how very likely it is that humans would have never happened in any "roll of the tape".

Gould is considered by many to have been the foremost expert on Darwinian evolution of the late 20th century (he is recently deceased), and his expertise shows through in the book. He writes well, but feels that a huge amount of detail on personalities, latin names and classification jargon is required to tell the story. I disagree; the book, while significant, borders on the unreadable to all but someone VERY interested in paleontology, evolution studies, and minutia of Gould's ways of thinking of the people involved in science.

The actual message is very simple; If one would "rewind the tape of evolution" (he says that a lot) to the point of the Burgess Shale and start again the odds that any of the rewinds would result in human consciousness are infinitesimal. Darwin, Charles Walcott, and most every textbook have an erroneous idea of the "cone of increasing diversity" in evolution that leads by "design" to man. I give Gould credit for not harping on the relationship (although it is mentioned) that Walcott still believed in a "designer" (God), so that influenced his thinking that "evolution was part of the mechanism", and therefore "directed". A more apt description might be "the wastebasket of evolution" and the "graveyard of creative destruction" as much of the massive diversity of the early Cambrian simply ceases to exist, and it the reasons for the destructed and the selected are unknowable to us, and probably much more "contingency" than "order".

The book drives home the point that there isn't any such "assumption of progress" or even idea that "progress" means getting to something like humans. Gould's "watchmaker" is not only blind, but purposeless. There is no thought that "a watch" is a worthy outcome. Gould seems to think that life showing up was "inevitable" (oddly, he provides no scientific basis for that, and nobody has gotten close to creating even the simplest of life in the lab).

Other than that "inevitability", even the development of the eukaryotic cell (the type we are made of, with the wall and structures in the cytoplasm) doesn't show up until 1.5 billion years ago. Gould suspects that this is another major league accident in planetary development that often wouldn't happen soon enough before sun depletion (something like 4 billion years) to give a decent chance at consciousness like ours. There is very little chance of the undirected, completely random evolutionary accident arriving at us (uh, "news at 11 I guess" ... this wasn't exactly a surprise).

I'm struck by how often very intelligent people find a flaw in one item that someone else had asserted for evidence of God, and immediately jump to the "SEE!, it isn't created!". Meanwhile, they almost always expand the odds against their own existence by some astronomical factor. Gould never provides an imagined "10 to some huge negative decimal" odds against humans showing up, but over and over he indicates how at MANY points in the random dance of evolution, if one "rewound the tape", there is no way we ever happen.

He brings up the "anthropic principle" that says "this is the universe we see, because we are here" as about the only possible explanation a dutiful atheist scientist can be left with. This explanation is pretty much "it is because it is", or "we did a lot of study, discovered that the odds against us defied explanation, so we decided that we are just here because we are".

Say you are on Death Row and I'm your lawyer. I come in and tell you that we have exhausted all appeals, but you will be released before you are executed because "I've never lost a capital case". Are you comfortable? Turns out that in the real world, I've never lost a capital case nor had one of my patients die in brain surgery! Therefore, by the sorts of odds of us being here in this universe, you ought to find me as a "reasonable choice" for a lawyer at a murder trial, or your brain surgeon if you need one! "We are here because we are" has just as much to suggest it as a wise answer philosophically.

I suppose if you are betting against God, then any explanation that lets you live without that concern is comforting. Gould allows us to stack yet another giant but unstated number against us being here on top of a stack from physics with the wonderful cosmological constant of 10 to the -120, not estimated by man, but DISCOVERED in the fabric of our universe saying, "It could be ANY number, none of the others allowing your existence.How do you like those apples?".

I find that simple premises in life tend to work best. The old "If you are in a game of chance and you don't know who the patsy is, it is probably you" has a lot of truth. That is also heavily related to "the house wins"-you just have to figure out who "the house" is. In Vegas, that is pretty easy, in the US, lots of folks would like you to believe "corporations", and I falsely went with that, thinking it was a good idea to "work for the house". Unfortunately, it is Lawyers. If you look closely at our system you find they are all the politicians, judges, and BOTH sides in any dispute. Take a look at John Edwards-oh, and BTW, how many Lawyers are running for President vs CEOs or even long term corporate employees? But I digress.

Lots of scientists and atheists seem to think that they can explain to God just how he can run his house. "If evolution doesn't look ordered to US, then it can't have INTELLIGENCE behind it"! Uh, and exactly what would it be that would give us the perspective to decide that as little more than pond scum orbiting on obscure rock on the outskirts of one obscure galaxy out of what we believe to be 100 billion galaxies in at least this universe?

If one wants to believe string theorists, that would be out of 10 to the 500 universes. Is even the definition of "intelligence" that simple? Isn't even defining what our yet not understood to ourselves consciousness does as "intelligence" in some universal sense a pinnacle of hubris WAY beyond the simple idea that the earth was the center of the universe? We have decided we KNOW the parameters within which an ultimate power can decide to create? We believe God wouldn't play dice, it looks random to us, ergo, there is no God.

I was glad to finally read a Gould book since I've heard a lot about him and seen him quoted by many atheists as a comforting; "See, he is a really smart piece mass of protein, he has done a lot of study and decided God didn't create life, so let's commit the unforgivable sin and maybe set up a website where teens can do it, because we are scientists and only think RATIONALLY".

Maybe so; if it happens that randomly generated protein arrived at the proper definition of "rational" then my hopes are in vain and life has the atheist desired lack of meaning. Strangely, it seems like other than really large odds against OUR existence, it is going to be hard to have any evidence for or against God.
