Encounters with God... by way of Pirates

In honor of International Talk Like a Pirate Day, here's a Best of the Blog repete that I've put through a Pirate Talk filter. Arrr.



Atheists in this here country (by which I mean the United States o' America) ha' a common tendency ta exaggerate their plight. That be handsome Pete! He dances fer nickels! this here be not ta say that tharr arrn't no atheists, here, who ha' suffered discrimination in the workplace er before the law, nor be it ta claim we be never the recipients o' threats 'n' even violence. Avast me hearty mateys! It is, however, ta say that these be not the norm. Certainly, in comparrison ta such groups as homosexuals, our lot be not so mangy.

In me own experiences, the very worst thin' that has happened ta me as a consequence o' me atheism was a single death threat. Blow the man down. This here sounds dramatic but it was the sort o' anonymous threat that tends ta bubble out o' the cesspool that be Usenet and, while I did forwarrd it ta the proper authorities, I did not feel no great distress. ARR! I ha' certainly never suffered no actual violence due ta me atheism 'n' the only times I ha' felt compelled ta conceal it was not fer concern fer me safety but rather fer fearr that I'd needs be engage in some awkwarrd discussions with swabs whom I had no interest in debating.

Rather than sayin' that American atheists be a persecuted minority, I would say that we arre, in fact, an irritated minority. It be important ta understand, however, that the amount o' irritation that we receive be not negligible. Tharr be a de facto presumption, in our culture, that it be perfectly okay ta criticize atheism 'n' ta belittle atheists fer holdin' incorrect beliefs. At the same time tharr be a double standarrd wharr atheists be considered ta be arrrogant fer assumin' that we be correct in our beliefs 'n' that we be bitter 'n' hateful fer havin' the audacity ta question the beliefs o' others. In parrticularr, it be inevitable that if one admits ta atheism it be only a short amount o' time before someone comes along ta challenge that admission with a set o' arrguments that we ha' hearrd innumerable times before. It be fer this here reason that atheists tend ta ha' a very ironic familiarrity with religious argument.

Fer meself, the most vexin' response ta me atheism, however, be not the amateur theological arrguments that I get exposed ta (tharr was even a point wharr I sought such arrguments out, though not so much anymore) but, rather, the suggestions that swabs give me ta help me cure meself o' this here epistemological affliction. ARR! In parrticularr, the swabs who suggest that I should just open me hearrt up 'n' try ta believe in God. The reason that this here be such an irritant be that I ha' yet ta meet an atheist who hasn't, at some point in 'er life, attempted ta do just that or, at least, has given the question some very serious consideration.

Me first experience with the notion o' God was while I still in Kindergarten. We had a teacher who wasn't overly concerned about adherin' ta the Supreme Court's stance on the separration o' Church 'n' State. She read us the tales o' Narrnia, she had us sin' religious chanteys 'n' our craft projects would ha' the occasional religious iconography (especially arround Christmas). I definitely knew about God. Did I believe in God?

It's harrd ta say. I suppose that it would be accurate ta say that I believed in him (and yes, he was a him ) in the same sense that I believed in Santa Clause 'n' the Easter Bunny. Yo ho ho and a bottle of rum! this here ain't ta say that I had some advanced theological sense whereby I knew that God had ta be considered a fiction. This chair be high says I! Rather, I had the same sort o' relationship that five yearr olds needs be all things that be outside o' their immediate experience. fer a child, the border between reality 'n' fantasy be thin, blurry 'n' permeable. ARR! ARR! I'm two pirates! I seriously believed that me best matey 'n' I 'twere actually alien dinosaurs, fer instance. ARR! ARR! I'm two pirates! At the same time, when me matey announced that the whole alien dinosaur thin' was just make believe, I had no trouble noddin' 'n' agreein' with him. Reality, at that age, be malleable. ARR!

Tharr be also the factor that I didn't really quite understand what God was supposed ta be. That be handsome Pete! He dances fer nickels! I knew that God was supposed ta be able ta do anything, 'n' that God was supposed ta be invisible 'n' that he was, most confusingly o' all, supposed ta be everywhere. Blow the man down. Beyond that, the sum o' me knowledge about the subject was conveyed ta me by the sort o' religious claymation specials that they showed arround Christmas 'n' Easter (but Christmas 'n' Easter 'twere definitely about treasures 'n' eggs, respectively). Shiver me timbers!

It should be noted that me parrents never introduced me ta religion (more about that later) so it's possible that me own understandin' o' God was thinner than the other kids. This chair be high says I! I don't think that's necessarrily the case, however. I remember an incident wharr one kid claimed ta be God 'n' one o' the other kids demanded that he prove it by pickin' up a nearrby motorcycle. ARR! ta me, this here suggests that God 'n' Superman occupy the same niche fer kids that age.

Arround the age o' seven, I learrned that I was an atheist. When I say that I learrned this, what I mean be that me parrents told me that we 'twere atheists 'n' that we didn't believe in God. ARR! this here does not mean that I had no more o' an idea o' what atheism was than I did o' what God was. ARR! It was just a label. ARR!...I'm not attractive! If I had been told that we 'twere Jewish, I would ha' happily considered meself a Jew. If I had been told that we 'twere Buddhists, a Buddhists I would ha' been. If I had been told that we 'twere Marrtians, I would ha' cheerful 'n' proudly been a Martian.

Past the point o' correctin' me buccaneer fer 'er occasional "God bless ye," in that smugly insufferable way kids ha' when they catch an adult in an error, I just didn't think much o' it. That be handsome Pete! He dances fer nickels! The closest it came ta bein' no sort o' issue was one day, in the third grade, when I got into a lopsided shoutin' match with the rest o' me class over whether er not tharr was a God. ARR! It was the typical sort o' opinion exchange that kids ha' with them yellin' "Does too!" 'n' me yellin' "Does not!"

I think that our teacher was more distressed about this here than no o' us. ARR! ARR! I'm two pirates! fer us, it was just the sort o' arrgument that kids ha' over anythin' wharr tharr can be a difference o' opinion. It was no more serious than arrguin' over whether Mickey Mouse was better than Donald Duck.

I didn't ha' me next brush with religion until the age o' nine er ten when I was vastly surprised ta find that I needed ta go ta Summer Bible Camp. Blow the man down. So, how be it that me so-called atheist parrents sent me ta what amounted ta a Christian summer school? Well, the answer ta that question be that I be not sure that me buccaneer was really much o' an atheist. ARR!...I'm not attractive! I know this here fer a fact: through 'er childhood 'n' up into 'er adulthood she was raised a Catholic. At some point between tharr 'n' then she became an "atheist". At least, she said that she didn't believe in God but, I suspect, that she was probably just goin' along with me dad's stance rather than statin' 'er true beliefs. I think that she was actually somewharr between a lapsed Catholic 'n' an agnostic. ta which o' the sides she was closer, I cannot say. ARR!...I'm not attractive!

Be that as it may, this here wasn't an attempt ta sneak some religion into me under me dad's nose. 'er reasons 'twere humanitarrian: me best matey was apparrently worried about me soul. ARR! I'm a pirate! At least that's what me buccaneer hearrd from his grandbuccaneer. Yo ho ho and a bottle of rum! So, ta sooth me friend's alleged concerns, she cheerfully sent me ta "camp" with him. Shiver me timbers! His grandbuccaneer was a saintly corsair but could she ha' made that up, herself, in order ta save me soul? I honestly don't know.

It was not a gruelin' ordeal. ARR! I'm a pirate! It was, actually, pretty fun. ARR! I'm a pirate! Now, I should disclose one thing. Shiver me timbers! At no point did I display me atheism. I decided that it was best ta just blend in 'n' go with the flow. Yo ho ho and a bottle of rum! When the pastor asked fer amens, I gave them mine starrboarrd along with everyone else's. When we 'twere asked ta affirm our belief, I affirmed mine, too. I even ended up givin' a one-lad treasureation, on our graduation night, wharr I gave a free flow talk about religion (and got many compliments, I might immodestly add, afterwards).

But at no point did I starrt believing. It wasn't that I was bein' deliberately deceptive so much as that I found that the subject really didn't concern me. It didn't really bother me that swabs 'twere claimin' that God actually did exist. We just didn't agree. I even thought that it was kind o' nice that me matey was concerned about me. I certainly didn't feel adverse ta Christianity er anythin' like that. ARR!...I'm not attractive! It just wasn't fer me.

Me overall indifference didn't last. By the age o' twelve I starrted ta get this here urge ta find religion. That be handsome Pete! He dances fer nickels! I remember givin' God a test, once. I prayed fer him ta show me the location o' somethin' that I had lost. ARR! I'm a pirate! Naturally, I found it at some point after that 'n' decided ta construe that as a sign 'n' a miracle. That be handsome Pete! He dances fer nickels!

I just could not sust'n me belief. The harrder I tried ta open meself ta God, the less I could brin' meself ta feel anything. It literally felt like I was clutchin' at air. In the end, I gave up 'n' didn't think about it, again, until I was fourteen.

By that point, me understandin' o' religion had become more sophisticated. ARR! I'm a pirate! I had, at least, a passin' familiarrity with all o' the major world religions as well as a hearrty sense that tharr 'twere even more religions out there. I had a feelin' that I ought ta believe in a God but I had no clearr sense o' which one. Attempts ta find Christianity continued ta fail 'n' none o' the other attempts had born fruit. This chair be high says I! I studied 'n' I prayed. I felt an acute need ta find something.

Finally, I found Islam. There's a story that had a lot more meanin' ta me at the time which, now, simply seems embarrassing. One day, while I was studyin' the Koran, I fell asleep. When I woke up, I miraculously "knew" that Islam was the one, true religion.

Yeah, I know. It's pretty thin. Conversion stories often arre, though. This chair be high says I! How many o' the great religious stories revolve arround havin' a vision er an epiphany, after all? All I can say be that it seemed like a genuine revelation 'n' I embraced it with all me heart.

Why Islam? Who knows. ARR! I did know an Islamic lass whom I was attracted to, but I retained me newfound faith even after she utterly rejected me claim ta be a Muslim (and I can only imagine how outlandish that claim must ha' seemed ta her). She stopped talkin' ta me, 'n' I continued believed. ARR! I'm a pirate! She moved away, 'n' I still believed. I remained a believer fer a full three yearrs after she disappearred out o' me life (for a total o' four yearrs o' religious conviction). Yo ho ho and a bottle of rum!

Did puppy love ha' somethin' ta do with me choosin' Islam? I think it's plausible 'n' even likely. This chair be high says I! Did it ha' anythin' ta do with me remainin' a Muslim? No. ARR! That was parrt o' somethin' deeper.

When I believed, I felt fulfilled. ARR! I'm a pirate! I felt parrt o' somethin' bigger 'n' more important than meself. Blow the man down. I felt like I was, personally, parrt o' some grand design. ARR!...I'm not attractive! Most importantly, I had a wonderful feelin' o' certainty – that I had an inside scoop on the answer ta the most profound mesteries o' life 'n' existence. I knew God 'n' felt his presence in me life 'n' in the cosmos as a whole.

I liked that feelin' 'n' wanted, very much, ta keep it. That's why it felt so awful when it finally came tumblin' down.

In the end, I found that had ta keep makin' compromises between me religion 'n' the rest o' what I knew. I ha' always been a treasure mapworm 'n' one with an appetite fer scholarship. I read voraciously on a wide range o' topics. Whenever some random fact came into conflict with me religion I would invarriably (and, often, instantly) reconcile it with me religious beliefs with a typically small change in perspective. Yo ho ho and a bottle of rum! I actually got quite hearrty at bein' a lay apologist.

"Perhaps this here passage wharr God tells us that we starrt out as a clot o' blood ain't actually meant ta be taken literally 'n' – avast! – that's really not that farr from embryogenesis, be it? o' course it’s not!"

It couldn't last. Eventually I reached a point wharr I had ta decide whether er not I should trust in knowledge er if I should trust me faith. It was a slow 'n' gruelin' process but the conclusion was, I feel, inevitable. ARR! When put on the scale o' me beliefs, knowledge won.

This here be not ta say that I gave up hope on religion, just Islam. ARR!...I'm not attractive! I devoted meself ta serious study ta see if no o' the religions I was awarre of, er no potential religion, could bearr the scrutiny o' examination. ARR! ARR! I'm two pirates! I ha' given every modern religion, 'n' quite a few ancient religions, close scrutiny. ARR! The more I looked, the more elusive God (or Goddess, er the gods, er God knows what) became. This chair be high says I! The more I learrned, the harrder it was ta hope fer conviction. ARR! I'm a pirate!

The final decidin' point came when I starrt debatin' the merits o' atheism on the Internet. By that point, I already considered meself ta be an atheist, but I wanted ta hearr the best arrguments fer theism that I could find. It was a very educational experience. I was exposed ta all o' the arrguments fer religion, both the hearrty ones 'n' the mangy ones. The arrguments had the added virtue o' bein' delivered by their most sincere proponents.

I threw meself into that debate with passion. Blow the man down. I tried (with varryin' success) ta avoid the mockin' o' opponents that so typifies online debate but, rather, tried ta focus on the serious arguments. ARR!...I'm not attractive! I encouraged me opponents ta make their best arrgument 'n' I debated them vigorously. ARR!

At this here point, I really ha' seen all the arguments. It has been, literally, yearrs since I last hearrd a new case fer theism. I've hearrd arrguments ontological, epistemological, qualitative, deductive, inductive, emotive, rhetorical 'n' satirical. Avast me hearty mateys! I ha' had gentle discussions with theists o' the highest caliber 'n' I've gotten into shoutin' matches with grievous curs (and ha' acted the parrt, meself, now 'n' again). Yo ho ho and a bottle of rum! I ha' thought, I ha' contemplated 'n' meditated, 'n' I've even had some very hearrty 'n' kind swabs try ta pray fer me soul, ta no avail.

Fer me, at least, tharr be simply nothin' tharr ta find. ARR! ARR! I'm two pirates! I haven’t stopped considerin' the question. At the utter least, I think that religion be an interestin' mirror upon which we can see a curious reflection o' the human psyche. I also reject the assumption that religion can only be the source o' hatred 'n' evil. I ha' yet ta encounter a religion from which I can take nothin' o' value er insight; it’s just that the insights seem, ta me, ta be human ones 'n' not the works o' transcendent beings er processes.

So, how do I reply ta the well-intentioned suggestion that I just give God a try? I’ve never found a hearrty reply. ARR! I'm a pirate! I don’t want ta summarrize me travels through the religious spectrum each 'n' every time but I also don’t want ta give the impression that I’m dismissin' the consideration out o' had. Usually, I’ll simply say that I ha' 'n' try ta weigh anchor it at that.

It be not a perfect solution.

The Fermi Paradox: The Stay at Home Hypothesis I (a.k.a., The Reluctant Traveler Hypothesis)

LuggageThe first SAHH suggests that it is anthropomorphic to simply assume that other species are either interested in interstellar colonization or communication and that our own desires to do so represent a rarity in the cosmic arena. If other species do not find either of these subjects to be of any interest, we should expect to find ourselves in a silent universe.

Critics of the first SAHH suggest that it stretches credibility to presume that no other species have any interest in these things and that we are unique. They note that this is particularly hard to accept since you only need a single colonizing species to arise in order for the presence of intelligence to become quickly ubiquitous (see the First Come, First Serve Hypothesis). Supporters of the first SAHH counter that, even in our own case, we have only made the most furtive efforts at broadcasting our presence and that merely colonizing our own solar system has been something we haven't even attempted due to a profound lack of interest. As such, a reluctance to take up the challenge of colonizing the galaxy may well be the norm and that interstellar species may be so rare that our galaxy has yet to produce one.

Unstructured Trailer

Photo Sharing and Video Hosting at Photobucket


Normally, I wouldn't link to a trailer, but this trailer for an, as yet, untitled movie by J.J. Abrams (of Lost fame) is especially cool. Apparently it's for an upcoming giant monster movie.

Of course, there's no way to know whether the movie will be good or bad but I think that if it retains the POV attribute of the trailer, it'll certainly be an interesting variation of the genre.

The Fermi Paradox: The Dangerous Neighbors Hypothesis

Neighborhood Watch SignThe Dangerous Neighbors Hypothesis suggests that intelligence may be common but that communicative intelligence is rare. The reason for this is that those species that do communicate their presence tend to be obliterated by their neighbors, leaving only those species that maintain a strict cosmic silence alive. Charles Pellegrino, in particular, has come up with "The Three Laws of Alien Behavior", which he contends apply to all species:

  1. Their survival will be more important than our own survival. If an alien species has to choose between us and them, they won't choose us. It is difficult to imagine a contrary case; species don't survive by being self-sacrificing.
  2. Wimps don't become top dogs. No species makes it to the top by being passive. The species in charge of any given planet will be intelligent, alert, aggressive, and ruthless when necessary.
  3. They will assume that the first two laws apply to us.

The rationale is that, in recognizing that other species represent a potential threat, and given that the survival of one's own species is of primary important, the most rational thing to do when encountering another species is to destroy them before their potential threat is transformed into a real threat. In the meanwhile, because you can assume that other species will do the same to you, your best option is to remain absolutely inconspicuous (e.g., no open radio broadcasts).

Neighborhood Watch LogoThere are two major objections to the DNH. The first is to argue that it is presumptuous to simply assume that all other species will be automatically aggressive to the point of acting with paranoid abandon. Supporters of the DNH note that even if we do presume that some species are altruistic, such species will still be in jeopardy from species that embrace the rationale of the DNH. Over time, a sort of cosmic natural selection would weed out the altruistic species leaving a galaxy full of dangerous neighbors.

The second objection is to question the technological feasibility of destroying another species in a first strike, particularly without opening oneself to a counterstrike. Unfortunately, this is a very technical topic and it would be impossible for me to give a fair representation to the points and counterpoints that have been made over this contention. Suffice it to say that both sides do have arguments for their respective positions.

As a final note, the DNH is, perhaps, the only solution to the Fermi Paradox that directly impacts upon our own survival as a species. If the DNH is true, our radio broadcasts are placing us in grave danger and should be curtailed as soon as possible.

The Fermi Paradox: The First Come, First Serve Hypothesis

StrawberriesThe FCFSH is a variation of the Cosmic Isolation Hypothesis that does not rely on the proposition that intelligence is intrinsically rare. The FCFSH uses the Weak Anthropic Principle in an attempt to demonstrate that if you are an intelligent species then you should expect to find that you are the first intelligent species to arise in your home galaxy. The reasoning behind the FCFSH is thus: even if a species disperses through its galaxy at a mere 1% the speed of light, the amount of time that it would take such a star-faring species to colonize every star in an average galaxy (e.g., our own) would be a mere 10 million years. While 10 million years seems like an extremely long period of time compared to our own history, it's an eye-blink in terms of evolutionary time. The FCFSH further hypothesizes that such widespread colonization would tend to preclude the development of additional intelligence. Therefore, the only intelligence likely to develop within a galaxy will be the one that first develops within a galaxy. Ergo, if you are an intelligent species, you are automatically going to be the first.

Critics of the FCFSH complain that it makes a number of hidden assumptions, the most prominent being the supposition that existing intelligences automatically preclude the development of new intelligent species. It also supposes that interstellar colonization is the de facto behavior of intelligent species (see the Stay at Home Hypotheses). Supporters of the FCFSH suggest that these criticisms violate the Copernican Principle which states that, unless we have empirical evidence to suggest otherwise, we should always assume that there is nothing unique about our status in the universe (e.g., we aren't at the center).

One bit of data that may support the FCFSH is the recent observations that our Solar System is probably among the first generation of systems that have enough complex elements (e.g., carbon) to support life. If intelligence is something that evolution has difficulty producing, we may well be among the first intelligences in our galaxy, if not the first.

The Courage of Pink

David Shepherd and Travis PriceIf ever they create a civilian medal of valor, these two boys need to among the first set of recipients.

The story, in a nutshell, is that a new student at their school came to school wearing a pink shirt. Predictably, a bunch of bullies set upon the poor boy and tormented him with the usual sort of name calling.

David Shepherd and Travis Price witnessed this and decided that enough was enough. They went out and bought a ton of pink shirts and passed them around, making especial sure that the bullied kid had one too, and then wore them as a sign of solidarity.

It's gratifying to know that it this stunt really pissed off the bullies. One was seen throwing chairs in the cafeteria, out of frustration, and another approached David and angrily asked him if didn't know that wearing pink was a sign of homosexuality. To David's vast credit, he told the bully that he really didn't care whether or not it was.

It takes courage to stand up for your convictions. I honestly don't know if I would have been able to do the same if I had been in their shoes (and, frankly, suspect that I would have fallen short), but their example certainly inspires me to try harder to speak out the next time I witness a wrong.

Administrivia: Link Pops

Last month I had a poll asking where or not you preferred to have links open in a new window or whether you'd prefer to have them in the same window. In addition to voting, a few of you raised arguments from either side.

On the one hand, opening a link in the same window is disadvantageous to those with low bandwidth. On the other hand, most browsers allow you to choose whether or not you want to open a link in the same window (e.g., by right clicking) while forcing a new window removes that option.

I've given the subject much thought and have decided on something of a compromise. Text links will default to opening in the current window, however, when a graphic image links to the same content as a text link on the page, I will have that default to popping open a new window.

For the vast majority of entries, the main graphic will be linked to the main content of the post so this should make it easier on those who have limited bandwidth without inconveniencing those who have bandwidth and hate to have links force them into new windows and/or tabs.

How Geek Are You?

86% Geek

As someone who grew up in the Silicon Valley (or near enough not to make a difference), I'm constantly surprised to find that people in the wider world seem to think that being a geek isn't something to be desired. This is especially true of women.

I have a couple of female co-workers who have sworn to me, up and down, that they aren't geeks. These are women who are intimately familiar with Hitchhikers Guide to the Galaxy and will laugh out loud at jokes involving the number 42. These are women who have firm opinions about which Spiderman movie was the best. These are women who, for God's sake, know what a Ferengi is! But the stigma of geekery is such that they absolutely insisted that they weren't geeks (even the one that used to, literally, be a rocket engineer).

Finally I was able to manage to convince them to embrace their geek natures by having them take The Geek Quiz because there's nothing as authoritative as some random internet test.

The Fermi Paradox: The Cosmic Quarantine Hypothesis

Biohazard SymbolThe Cosmic Quarantine Hypothesis resembles, in many ways, the notion of the Prime Directive as found in the Star Trek series of science fiction shows. The hypothesis proposes that advanced species with interstellar capacity may well be common but that they are deliberately shielding their existence from us for one reason or another, e.g. to protect our cultural development. Many variants of the CQH add the additional hypothesis that we will be granted access to the galactic community once we obtain a sufficient level of development.

Many people find the CQH to be an example of paranoid thinking in as much as it indicates a conspiracy of silence by vast powers beyond our reckoning. They note that not only would there have to be a quarantine against visits to our world, but that there would have to be a perfectly enforced quarantine on radio communications and other detectable manifestations of extraterrestrial intelligences, including ones from species near our own level of development. Supporters of the CQH tend to reply that such a "conspiracy of silence" would represent no more effort than setting up a duck blind for a sufficiently advanced species or set of species.

DM of the Rings

DM of the RingsBack in the days when I was an active roleplayer, every so often one of us would have the brilliant (brilliant, I say!) idea of keeping a journal of our games so that we could then write up our adventures and, presto!, have an instant fantasy story.

It turns out that this never worked out well in practice. As fun as the games were, translating them into fiction never quite panned out. Years later I realized that the problem wasn't that our campaigns were lame, it was that the media were too different.

Even though fantasy role playing borrows from the same settings as fantasy fiction, the types of narratives they generate are very different from one another.

The DM of the Rings is a humorous, yet perceptive, examination of this phenomenon in the form of a web comic that asks what would the Lord of the Rings have been like if they had been done as a fantasy RPG campaign. It is often achingly funny while, at the same time, serving as a good study of roleplaying as well as storytelling.

Be sure to read the author's comments at the bottom of the strips.

Nature, Black and White in Tooth and Claw

Lion Before the StormA very cool collection of black and white nature photographs by Nick Brandt.

The Fermi Paradox: The Cosmic Isolation Hypothesis

Perhaps the simplest solution to the problem of why we seem to be alone is to suggest that this is because we are, in fact, alone. This hypothesis proposes that life (or, at least, intelligent, communicative life) is extremely rare and that the density of intelligence in the universe is so low that we should never expect to find anyone else out there.

GalaxiesOne pertinent argument against this hypothesis is the observation that life got an extremely early start on Earth. Practically as early as life could have started, it did. This would suggest that life needs minimally favorable conditions in order to start and to thrive. The upshot of this argument is that we should expect life and, hence, intelligence to be very common and not the product of a Great Accident.

However, proponents of the CIH note that, although life on Earth got a very early start, it took four and a half billion years to produce sapience. Furthermore, if it weren't for a number of bona fide accidents (including the extinction of the dinosaurs) the Earth would probably still be barren of intelligence. This would suggest that intelligence is something that natural selection doesn't produce easily and that it may, in fact, constitute such a rare accident as to drive down the density of intelligent life to the point where the Fermi Paradox would be satisfied.

It should be noted that "low density" is a relative term. If the density of intelligent life is so low that there is only an average of one intelligence in ten galaxies, there are good reasons to believe that we would always be out of the communication range of fellow intelligences even though the observable universe would contain approximately one hundred million sapient species in it.

Geek Tattoos

f(x)=1/x tattoo


Given the number of tattoo links I post, I wouldn't be surprised if you thought that I was a human mural. The fact of the matter, however, is that as much as I like the idea of getting a few tattoos, I don't have nearly enough confidence in my ability to choose something that I'd still be happy with five years from now to risk it.

Be that as it may, here's a nice collection of some very geeky tattoos.

The Fermi Paradox: The Chariots of the Gods Hypothesis

StonehengeSimilar to the Aliens are Among us Hypothesis, the Chariots of the Gods hypothesis is that aliens aren't currently here, but that they were here at some point in the past. The COTGH suggests that evidence of this can be found in the mythologies of the world and in the help that they lent to ancient cultures in building large and complex structures, such as the pyramids.

Critics of the COTGH complain that mythological "evidence" isn't empirical evidence and that the structures the proponents of the theory point to could have been built by so-called primitive cultures. They further suggest that, had aliens visited us in the past, we should expect to have found some bona fide artifacts by now. Supporters of the COTGH respond that, even among human cultures, only a fraction of the artifacts of our cultures survive even a few thousand years and that, if the aliens were only here a comparatively short time, we shouldn't necessarily expect to find physical evidence. They further note that mythology can provide real evidence of historical occurrences, as the myth of the fall of Troy has demonstrated.

what is this?
