Today: Are religions naturally evolved?<img style="width: 310px; height: 193px;" name="cartoon" src="http://www.funnytimes.com/archives/files/art/19990203.jpg" alt="caption: " border="0" /><br />A while back, I asked myself (and a colleague): could it be that religion is the product of evolution? After all, there is abundant evidence that people(s) make god(s), while the evidence for the converse is, uhm, spotty to say the least... Neither he (nor I) were totally clear on the answer. But now I think the question falls into the "sounds harder than it is" category. This apparently hard question has an easy (i.e., intuitively plausible but also, I think, correct) answer: Religions seem to answer the big questions, such as "<a href="http://www.funnytimes.com/archives/files/art/19990203.jpg">what's it all about</a>" quite well.<br />An evolutionary and systems theory explanation: Once your control system ("brains") get big enough, self-consciousness and other complications arise. And then you rather naturally ask questions such as "why am I here", "where do I come from", and "what's it all about". Big brains => self-aware then self-consciousness => trouble. But religion delivers the reassuring answers: Relax, it's all good. You're here for a purpose. In fact, the whole darn universe is made for you (in some religions, anyways) -- even god (or his son) looks just like you!! (Carl Sagan calls this "the human conceit" and quibs "oh my -- what a coincidence" ...) Of course Darwin delivered a major narcisstic injury, explaining away the need for the sky-daddy (even if he didn't like this repercussion himself).<br /><br />So this explains it: We (having evolved large brains and asking the "big questions") want comfort and reassurance that all is good. Religion caters to that need. So say we all.<br /><br />Daniel Dennett also studies and explains religion as a natural phenomenon in <a href="http://en.wikipedia.org/wiki/Breaking_the_Spell">Breaking the Spell</a>. Turns out that the evolutionary argument for religion has also been evoked to ask: If religion evolved naturally, then it must be good for something, right? We don't just evolve characteristics for nothing. So what's the purpose of having evolved religion? Dennett points out that the flu also naturally evolved. What's it good for? It's good at being copied and spread. I think the same applies for religion, but we have these additional levels of explanation: it's good at providing answers, makes you feel good about yourself and the world (restrictions apply: some traits make you feel really bad, you immoral sinner! But that's another story...); it can also help group cohesion, channel ideas, organize masses, etc. But above all, it gives you answers!<br /><br />Next time: Religion, genes, and memes: <a href="http://en.wikipedia.org/wiki/Cui_bono">Cui bono</a>?<br /><br /><a href="http://en.wikipedia.org/wiki/Breaking_the_Spell"> </a>Powers-Of-Tenhttp://www.blogger.com/profile/17610825523003957542noreply@blogger.com0tag:blogger.com,1999:blog-3920586529248990232.post-85603705523584823672008-11-22T23:24:00.001-08:002008-11-22T23:24:59.884-08:00Are you dead or are you alive??At this time of the year, walking across campus, one cannot fail to notice <a href="http://en.wikipedia.org/wiki/Acorn">acorns</a> all over the grounds.<br>Quite impressing this amount of acorns that an oak can produce...<br> Looking at those acorns, one might ask: <a href="http://www.youtube.com/watch?v=WHZy4p9EH4M">Are you Dead or are you Alive?</a> <br>(incidentally, in my younger years I was at a <a href="http://www.thebusters.com/%20">Busters</a> concert ... lang ist's her... and that song was one of the "Earworms" back then)<br> <br>Of course the question could be considered a category error: An acorn is not literally alive (nor really dead), but has the "potential of life".

But a bit less so when one instead says "Objects are over-rated: It's the process stupid!". (I must be paraphrasing incorrectly now for sure). The latter (think process, not object!) I find more agreeable and understandable: A problem arises when we think of subjects and living things/beings (as objects) -- Where do "they" go when the "body dies"? That's when you have to invent the "soul": The body dies, but the soul lives on.<br> <br>Sounds good. Many religions have this idea in common -- there is more to life than the body, and that other part (the non-body) goes on forever (into plus infinity); and in some religions probably that other part has been there forever (from -infinity; assuming birth is t=0). For example the old Egyptians had the Ka (a kind of eternal life force) and the human body was just the proxy here on Earth (I have these constant doubts whether I'm paraphrasing correctly -- go check wikipedia yourself ;-)<br> <br>So what do we know today: The cells of any living thing (or better: living being; even better: living process) have usually a short lifespan. Your identity is not the identity of your cells. Cells are coming and going, but "you" are still the same (or so you think).<br> Similarly, you are not your atoms, since atoms in your body are coming and going as well. So you can calculate an "average turnover rate" at the cellular level (e.g. based on the average age of cells in your body) and at the atomic level (e.g. based on the average time an atom resides in your body before it moves on to other things). With atoms and cells coming and going, the importance of "object-orientation" (in the conventional, i.e., material sense) as the basis for your identity or what anybody is or who we are is clearly overrated.<br> We are not the "stuff" we're (temporarily, at a given point) made of (In the "stuff sense" though, we still are what we eat -- the atoms that make up are body come from the food we eat; but then again those are replaceable).<br> So we are process, not object. <br>What about information? Are we information? Well, a lot of what we are or rather what we can be (as a process) is determined by our "initial program": An individual's genetic make up. The sum of all information stored in the DNA of an individual. The same such "programs" runs billions of times in parallel in the body of a living being. Just watch one of those amazing animations that show how RNA is made from DNA and proteins are made from RNA. This process and many, many more are constrained in what they can do by the DNA. But it's not just "nature" -- there is also "nurture". Environmental factors can't be neglected either. You can view this as a set of "parameter settings" that determine how "the program" is to be interpreted at a certain time. Those parameter settings can be different e.g. in "identical" twins -- and they can even change over time.<br> <br>So we are not "just" information or just a program. The program (say encoded in DNA) has to become "alive" in a proper "runtime environment". A running program is a process. The process follows the logic given by the program but quite different processes (and thus different process histories) can result via different "parameter settings". Past settings can influence future settings. We can think of the process as having "state" or memory. Using this terminology, things can be explained simply: A living being is a process, constrained by a program, and "initiated" at birth. Procreation is really spawning of new processes. If a process terminates, the program might still be around (e.g. in an identical twin), but the process and its history (determined also by parameter settings) are unique.<br> There are at least two kinds of memory / state in the system: at the individual process level, there is the "local memory" of the process. When looking over longer periods of time, spanning many generations, we recognize that some information is memorized in the program itself. The program "learns" and remembers a certain new "program logic" over time. We call this "genetic information" and genes the carriers of that information (Similar to genes, it can be hard in a program to localize which part of the program is causing which behavior. There are not just local switches and variable settings to consider, but the interplay of code fragments).<br> Process spawning (procreation) in nature is a bit more complex than in Unix: Often (but not always) there is not one parent process but two: The programs are "merged" in a particular way to create a new program. Then that new program is started. Check the process table (ps -elf) for details ;-)<br> <br>A little while ago, one of my child processes awoke this parent process. At which point the above thoughts were output by the parent.<br>Now all three current children processes need some interaction with the parent, else they go "out of bounds" (and we don't want any segmentation faults here). I love them very much.<br> <br>So why did I call this the big misunderstanding: I think much of the above view is correct. But it is often misunderstood. Or rather many people say body and soul when they mean process and program. In that sense, the soul leaves on (almost) forever -- but with modification... <br> </div> Powers-Of-Tenhttp://www.blogger.com/profile/17610825523003957542noreply@blogger.com0tag:blogger.com,1999:blog-3920586529248990232.post-87485177581710293392008-07-20T09:04:00.000-07:002008-07-20T09:05:00.338-07:00The Emergence of Meaning<div dir="ltr">It has long been known that marketing say for cigarettes, soft-drinks, cars, whatever, works well when the focus is not on the product (carcinogenous tobacco, colored sugar-water, etc.) but on the image evoked by the brand (freedom, coolness, success, ...)<br> After munching a not-so-good <a href="http://www.kinderpingui.de/">Kinder-Pingui</a> snack ("Kinder" = German for "Kids"; not to be confused with 'kind' as in 'being kind'), I realized that the marketeers behind <a href="http://www.kinderschokolade.de">Kinderschokolade</a> had a really smart idea when linking in the consumers' minds kids, milk, chocolate with their various products. Of course there is nothing healthy (or not much milky for that matter) in those Kinder-products.<br> <br>This seems to me another instance showing how gullible and easily manipulated we are as a species. Or rather how much we are interested in ideas (healthy milk snack) and not the boring reductionist view (oversugared, overprocessed junk food). Didn't someone say it's all about perception?

The evolution occurs through random innovation. Our effort is trying to view the evolution of this artifact from memetics. By constructing a phylomemetic tree based on cellular phone memes to infer or estimate the evolutionary history and relationship among cellular phone. We adopt several methods, which are commonly used in constructing phylogenetic tree, they are UPGMA algorithm and Parsimony Maximum algorithm to construct cellphone phylomemetic tree. Therefore we compare with the innovation tree, which is based on serial number and their appearance time. From phylomemetic tree, we then analyze the process of a cellular phone innovation through looking out on the cellular phone type lies in the same cluster. The comparison of the simulation tree result shows a generally different branching pattern, giving a presumption that innovation in cellular phone is not really relating with their serial number, but occurs merely because of random mutation of allomeme design and competes with its technological development.<br /></blockquote><br />What can I say... <a href="http://en.wikipedia.org/wiki/Alice%27s_Adventures_in_Wonderland">Curiouser and Curiouser</a>...Powers-Of-Tenhttp://www.blogger.com/profile/17610825523003957542noreply@blogger.com0tag:blogger.com,1999:blog-3920586529248990232.post-80288470233386942592008-04-06T20:28:00.001-07:002008-11-13T03:55:21.311-08:00All models are wrong, but some are useful.

A catch is that when comparing the complexity of explanations, there might not be an obvious measure. What looks simple to some (God did it) might look complex to others (Which God? Where From? How?), and vice versa, i.e. what might look complex to some (details of adaptation, "irreducible complexity", chicken-and-egg, etc.) is in fact simple to explain for those in the know (e.g. those who understand how evolution through natural selection works). So while objectively natural explanations trump supernatural ones every time, very much in line with Occam's razor, the <i>perceived</i> complexity by individuals might yield a non-parsimonious outcome ("God did it") that's considered simple by the individual.<br /><div><br />I was reminded of this when reading Jürgen Schmidhuber's <a style="font-style: italic;" href="http://arxiv.org/abs/0709.0674">Simple Algorithmic Principles of Discovery, Subjective Beauty, Selective Attention, Curiosity & Creativity</a>:<br /><br /></div><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"><i>According to our complexity-based theory of beauty [15, 17, 25], the agent's currently achieved compression performance corresponds to subjectively perceived beauty: among several sub-patterns classified as 'comparable' by a given observer, the <b>subjectively most beautiful is the one with the simplest (shortest) description, given the observer's particular method for encoding and memorizing it</b>. </i></blockquote><div><br />Similarly, from the abstract:<br /><i><br /></i><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"> <i> I postulate that human or other intelligent agents function or should function as follows. They store all sensory observations as they come - <b>the data is holy</b>. At any time, given some agent's current coding capabilities, part of the data is compressible by a short and hopefully fast program / description / explanation / world model. In the agent's subjective eyes, such data is more regular and more "beautiful" than other data. It is well-known that knowledge of regularity and repeatability may improve the agent's ability to plan actions leading to external rewards. In absence of such rewards, however, known beauty is boring. Then "interestingness" becomes the first derivative of subjective beauty: as the learning agent improves its compression algorithm, formerly <b>apparently random data parts become subjectively more regular and beautiful</b>. </i><br /></blockquote><br />Science v.s.

A bit like Pollan's corn domesticating us, instead of the other way round.<br />Or the inversion in 'office automation': we used to be in charge. Now we've become <a href="http://powersof10.blogspot.com/2008/03/are-you-gmail-transducer.html">gmail transducers</a>.<br />The idea is not new... but can still be intriguing. Biologists can tell you all about it: Check out <a href="http://en.wikipedia.org/wiki/Co-evolution">co-evolution!</a> Who is the parasite and who the host?<br /><br />Anyways, here's another one: When you get up at 3am in the morning, and half-asleep stumble to find a pencil and paper to write down an idea. Why then are we saying that <blockquote><span style="font-style: italic;">I had an idea! And I had to write it down! </span></blockquote><br />Are <i style="font-weight: bold;">we</i> really <i style="font-weight: bold;">having</i> an idea?

Sort of... and after all, we have free will, right?<br /><br />So how is your free will coming along recently, as you are consuming a constant stream of incoming messages, reacting to it by producing a stream of outgoing message, slavishly following a Getting-Things-Done scheme?<br /><br />Wikipedia says:<br /></p><blockquote><span style="font-size:100%;">A <span style="font-weight: bold;">transd</span></span><span style="font-size:100%;"><span style="font-weight: bold;">u</span></span><span style="font-size:100%;"><span style="font-weight: bold;">cer</span> is said to <i>transduce</i> (i.e., translate) the contents of its input tape to its output tape, by accepting a string on its input tape and generating another string on its output tape.

A transducer may also produce no output for a given input string, in which case it is said to <i>reject</i> the input.<br /><br /></span> </blockquote>Sounds familiar?

OK, that's nothing new. But the way in which practically everything is connected to everything else continues to amaze. Probably because many of the connections happen in our own minds---and who knows how often---<span style="font-weight: bold;">only</span> there..<p>Take <a href="http://www.djerassi.com/cantor.html">Cantor's Dilemma</a> (the novel). A real page turner. As it so happens, it deals a lot with reproducibility of a scientific experiment. Sounds familiar, when you deal with scientific workflows, their automation and reusability. So there's one link to some of my other interests. Or how about this: Cantor's Dilemma (the paperback) was lying on top of "<a href="http://plus.maths.org/issue37/reviews/book2/index.html">A Different Universe</a>" by <a href="http://en.wikipedia.org/wiki/Robert_B._Laughlin">Robert B. Laughlin</a>, a Nobel laureate in Physics from Stanford. On May 22nd this year he gave a lecture at UCD. Surprisingly few people showed up (I suspect absence of PR/advertisement was at least a contributing factor). He gave an interesting talk with (too?) little physics in it. Anyways, I bought the book and asked the famous author to sign it. In his talk, Laughlin mentioned how getting the Nobel wasn't such a big deal after all (lots of eating he mentioned). He also mentioned in his talk (and his book, Chapter 7) a trip to the Neckar valley in honour of the 60th birthday of Klaus von Klitzing, Nobel laureate of 1983. After the talk, while having the book signed, I chatted briefly with Laughlin about the Neckar valley -- which happens to be where I was born. </p><p>So Djerassi's book was lying on top of Laughlin's; I had started the latter first, but finished the former sooner.. (eh? Yes.) But there's another connection: Djerassi describes in his novel quite a bit of detail what's going on at the Nobel festivities. This is a nice connection I think -- a novel by a scientist about some interesting happenings surrounding a (fictious) Nobel prize for cancer tumorgenesis; and real Nobel's book on "reinventing physics from the bottom down". </p><p>It's a small world indeed. And don't me get started on musing where all that life came from ... or those atoms for that matter...</p>Powers-Of-Tenhttp://www.blogger.com/profile/17610825523003957542noreply@blogger.com2tag:blogger.com,1999:blog-3920586529248990232.post-87302496591466477802007-06-09T23:26:00.001-07:002008-03-30T13:49:47.324-07:00Gretchen-Frage (Inconvenient Question)There is an idiom in German called "Gretchen-Frage". In a nutshell, posing a "Gretchen-Frage" ("Gretchen's Question") means to ask something crucial (for the questioner) and inconvenient (for the questioned), i.e., a question which the respondent might not like to answer directly. In addition to the inconvenience aspect, it is also implied, I think, that the question is "big". Let's see how it came about: In Goethe's Faust, the studied Dr. Faust, aided by Mephisto with whom he made a certain pact, falls in love with the much less studied, younger, conservative, innocent, catholic young woman called Margaret (aka "Gretchen"). Here is what she asks him:<br /><br /><blockquote>MARGARET:<br />Promise me, Heinrich.<br /><br />FAUST:<br />Whatever I can.<br /><br />MARGARET:<br /><span style="font-weight: bold;">How is it with your religion? </span>Please admit--<br />Your certainly a very good man,<br />But I believe you don't think much of it<span style="font-weight: bold;">.</span><br /><br />FAUST:<br />Leave that my child. I love you, do not fear<br />And would give all for those whom I hold dear,<br />Would not rob anyone of church or creed.<br /><br />MARGARET:<br />That is not enough, it is faith we need.<br /><br />FAUST:<br />Do we?<br /><br />MARGARET:<br />Oh that I had some influence!<br />You don't respect the holy sacraments.<br /><br />FAUST:<br />I do respect them.<br /><br />MARGARET:<br />But without desire.<br />The mass and confession you do not require.<br />Do you believe in God?<br /><br />FAUST:<br />My darling who may say<br />I believe in God?<br />Ask priests and sages, their reply<br />Looks like sneers at mock and prod<br />The one who asked the question.<br /><br />MARGARET:<br />Then you deny him there?<br /><br />FAUST:<br />Do not mistake me, you who are so fair.<br />Him--who may name?<br />And who proclaim:<br />I believe in him?<br />Who may feel,<br />Who dare reveal<br />In words: I believe him not?<br />The All-Embracing,<br />The All-Sustaining,<br />Does he not embrace and sustain<br />You, me, himself?<br />Does not the heaven vault above?<br />Is the earth not firmly based down here?<br />And do not, friendly,<br />Eternal stars rise?<br />Do we not look into each other's eyes,<br />And all in you is surging<br />To your head and heart,<br />And weaves in timeless mystery,<br />Unseeable, yet seem, around you?<br />Then let it fill your heart entirely,<br />And when your rapture in this feeling is complete,<br />Call it then what you will,<br />Call it bliss! heart! love! God!<br />I do not have a name<br />For this. Feeling is all;<br />Names are but sound and smoke<br />Befogging heaven's blazes.<br /><br />MARGARET:<br />Those are fair and noble phrases;<br />The priest says something, too, like what you spoke--<br />Only his words are not quite so--<br /><br />FAUST:<br />Wherever you go,<br />All hearts under the heavenly day<br />Say it, each in its own way;<br />Why not I in mine?<br /><br />MARGARET:<br />When one listens to you, one might incline<br />To let it pass--but I can't agree,<br />For you have no Christianity.<br /><br /></blockquote>OK, so much for that :)<br />And here the same in the original German. If you please.<br /><br /><blockquote>Der Tragoedie erster Teil<br /><br />Marthens Garten<br /><br />Margarete.
