We’re under Darwinist attack Captain Picard!
Post by PZ Myers a member of the out cAmpain.
That smart guy, Carl Zimmer, has written an article on those smart molluscs, the octopus. I like that his conclusion is that we can’t really judge their intelligence, because it is different than our own.
That’s the same answer I give to questions about the existence of intelligent life in the universe. I suspect that it’s there (but rarer than most astronomers seem to think — intelligence is an extremely uncommon adaptive strategy here on Earth, as is probably likewise elsewhere), but that it will be radically different in intent and action than our own, as different as we are from a squid, or a dolphin, or an elephant, to name a few forms that have evolved large brains. Often, the question of alien intelligence is more like, “Are there people like us out there?”, and I think the answer to that one is clearly no, almost certainly not. There are too many alternative pathways.
I think that life is far rarer than most science enthusiasts assume. I know the numbers are big and there most certainly are many planets with water and the proper temperatures in this enormous universe. But the actual conditions that are required for replication to begin is in my guess very, very rare. However, once replication does begin convergence seems highly probable. Heads with sight, sound and smell detectors are going to be vital in any environment. Legs for locomotion and arms with hands are essential for environment manipulation. We’re so close in abstract terms to all the vertebrate mammals. Nearly identical when you use relativity as a judgment.
I also believe in an infinitely cycling universe because of the conservation of energy. Therefor, I think that life emerging from non life is inevitable when limited time isn’t a consideration. So even though I’m an atheist and don’t give any credence to personal reincarnation, I believe that there are indeed “people like us” out there, a “divine” natural design. The real question is when.
Stephen Wells said, Why would a head be vital to the gas giant airbags of zebulon-B, whose senses operate at radio wavelengths and whose intellect is dispersed among the swarm? Or to the megaclams of Gwflhrx, whose perimeter is studded with a thousand eyes and whose nerve ganglia are safely protected deep within their mighty shells?
J said, Sorry PZ, but that’s way too broad to actually mean anything substantial. What are you talking about when you say “people”? Bipedal and two-eyed, with penises and vaginas? Nobody subscribes to that notion of extraterrestrial life.
On the other hand, some traits of human life which are special on Earth (e.g. language) might conceivably have evolved many times in the observable Universe. Maybe they’re what Dan Dennett calls “Good Tricks”, which are prone to being converged upon independently.
Even within the swarm there are individuals and the head is a most efficient way to give the body the ability to navigate. I’ll have to give the megaclams of Gwfhrx more thought but I don’t know how far they would get manipulating their environment. Environment manipulation, I think, is a fair way to judge intelligence. Too much manipulation by the highly intelligent might be a good sign of idiocity.

After completing my painting of Canal street with the billboard stating “Impossible is nothing”, I’ve been thinking about writing about the phrase. The ambiguous words have fascinated me because they can imply very different philosophies. “Nothing is Impossible” comes from the ADiDAS sports ads, which is simply a carpet motivational statement meaning next to nothing. A human being will never run as fast as a cheetah. The reason the statement caught my attention was because it’s very similar to where my philosophy originated from. My friend Jamie asked me what the opposite of a spoon was and the answer I deducted, no-spoon, was my first step down a path of thinking about zero. The opposite of anything is the lack of that thing (the empty set), noanything is pure zero and to ever have it is impossible. That, which at the time I didn’t recognize as the first law of thermodynamics, sent me thinking about nothing for quite some time. I was overwhelmed by the power the knowledge of zero had over me. I’ve yet to meet another atheist who made the switch to naturalism is such a manor.
