<br />
<blockquote class="tr_bq">
"Reductionism requires a stratified view of nature: that there are various levels to it, the relatively lower being more fundamental and explanatory than the higher. But what would these levels be? how are they defined and what are their boundaries? Is meteorology more fundamental or less so than economics? And are these facts about the world or more to do with our explanatory practices?"</blockquote>
This directly connects to Hierarchy Theory from the 1970s which as also related to Bertallanffy's work. This is al a question of systems and how the parts are put together. This also relates to Simon's Science of the Artificial which I still need to read which in turn is connected the Laurillard's current view of learning.<br />
<br />
I can also see links to non-extensive entropy. Reductionism depends on everything following equi-partition but space and history make the world heterogeneous and entropy cannot possibly be extensive, it cannot be additive because of the hierarchy of levels making more permutations and combinations of new emergent objects accessible. This is the power of symmetry breaking.<br />
<br />
This also fits with network models and the large central component and how to break networks into different levels when they are not homogeneous in their character.<br />
<br />
Everything depends on networks and systems and hierarchy. These produce complexity but are stable to change and evolution. It is all incredibly deep with layers within layers and out current understanding is incredibly superficial because we do not make enough connections. We have become so compartmentalised in knowledge that we cannot possibly move to the next level unless we break down these boundaries. They affect how we think, how we learn and how we work.<br />
<br />
I cannot believe that there is not a more extensive literature on finding sub-groups in data and showing if they are real or just useful explanations. This is the same argument that Mach was having with Boltzmann 120 years ago and the reason Boltzmann killed himself. Now we consider atoms real and not useful constructions of our intellect but within data and populations can we find REAL subgroups?<br />
<br />
I think from experiment that they exist and that there are giant central components of most populations with other groups which can be divided off, but is this just the normal distribution and outliers or do we get a Paretto like distribution as the population is broken into sub-groups? From breaking sequence data into sub-groups I get interesting results but are they real lineages or are they just practically useful?<br />

Actually says "not, needless to say, because I believe they are more central to a university than the natural and social sciences, but partly because their character and value are usually less well understood than that of the scientific disciplines, and partly because they are the disciplines with which I am most familiar."<br />
<br />
Chapter One - his idea is that the university is an important name for an institution because of the respect and prestige that the title brings. Very powerful arguments about the weaknesses of league tables and the ability to game them. Especially cynical about what league tables measure and if the student experience is a valid measure of anything at university.<br />
<br />
Chapter Two - Anderson Committee 1960 created student grants - just as the boomers were about to enter. Before that entry was based on unequal privilege.<br />
<br />
Chapter Four - Humanities are discussed but he is wrong to say that science and academic work should be inaccessible. His view that academic work is an apprenticeship in the humanities is a good one. We are all at some time apprentices even in the lab.Andyhttp://www.blogger.com/profile/17784856869056663331noreply@blogger.com0tag:blogger.com,1999:blog-3504366798345365263.post-45294056216012291182013-07-02T04:43:00.001-07:002013-07-02T04:43:50.383-07:00The Origins Of Sex p101<br />
... the Reverend Robert Wallace meant complete liberty for both men and women to cohabit successively with as many partners as they liked, and an end to spurious notions of female delicacy - for ' a woman's being enjoyed by a dozen in proper circumstances can never render her less fit or agreeable to a thirteenth!.<br />
<br />
<br />
p109 Ultimately and paradoxically, sexual appetite was both the basis of civilisation ' the first and original principle of human society' and an ever present threat to social bondsAndyhttp://www.blogger.com/profile/17784856869056663331noreply@blogger.com0tag:blogger.com,1999:blog-3504366798345365263.post-73381914207621930092013-05-12T04:19:00.000-07:002015-12-09T01:22:14.956-08:00The Fix - Damian Thompsonp92 Nonetheless, there is a common denominator: availability.<br />
<br />
Here he is looking at opium addiction in China and for US G.I.s during Vietnam and to gin in London. Dumb argument and the one usually used by the anti-legalisation crowd is that availability creates addiction. Yes if something doesn't exist I cannot be addicted to it. But there are plenty of addictive things that are freely available to which not everyone is addicted - cigarettes are not illegal yet and there are non-smokers. Doctors have wide access to drugs and not all of them are addicts (although more might be than is admitted). What they also all have in common is high stress/anxiety and low self worth with high levels of deprivation and the desire to escape life.<br />
<br />
p107 This dismissed the popular notion of sugar as 'empty' calories. On the contrary, they were <i>bad</i> calories. "A little is not a problem, but a lot kills - slowly," said the authors, who went on to propose that sugary foods should be taxed and their sales to children under 17 controlled.<br />
<br />
Yes there is a chance of increased levels of Diabetes and that is a very great cost to healthcare. Cup-cakes are a danger to society. This is not to be scorned and is easily dealt with and this is not an infringement of civil liberties it is education.<br />
<br />
p192 The most explicit video games create scenes of digital violence so extreme that they are closer to a serial killing rampage than even the bloodiest warfare. Some games even allow players to simulate an act of necrophilia on the body of a fallen opponent.<br />
<br />
Paranoid madness - he does not cite any literature on the link between violence and video game violence and he does not even name the game. This is hearsay, urban myth made into print. They are pixels coloured red and you get to hear worse on the news (Saville for example)<br />
<br />
p192 On the other side of the fence are the anti-gaming campaigners such as Baroness Greenfield, a professor of synaptic pharmacology at Oxford University who argues that digital technology is exacerbating autism spectrum disorders and leading to an increase in violence and distraction amongst children.<br />
<br />
Greenfield does look like an authority with all her books and interviews and appearances. What she fails to produce is any real scientific evidence to any of her claims. She has yet to publish one peer reviewed scientific article that presents any evidence of her claims and she is often attacked by people such as Ben Goldacre for making spurious and unsubstantiated claims.<br />
<br />
p197 The internet has an almost magical ability to arouse male sexual cravings.<br />
<br />
If he actually was not a sexist unable to relate to female sexuality he would also know that women also have sexual cravings and that these are also arouses by the internet although in different ways. He might like the book The Joy of Cybersex written by Deb Levine to show him a positive female view of sex on the internet.<br />
<br />
p198 you are wrestling with obsessions that until a few years ago you thought were confined to ferret-faced men in raincoats hanging around school playgrounds.<br />
<br />
This is a ridiculous stereotype. A lot of those who are paedophiles look like respectable members of the community because that is how they are most likely to get an opening for grooming young children. He forgets all the Catholic Priests for example that would hit too close to home as a devout Christian and Catholic as well as religious correspondent.<br />
<br />
p202 I don't think anyone would have anticipated the features of porn that unnerve us most today: the massive appeal of hard-core images, often involving teenagers or children; and its transformation from a bad habit into an addiction.<br />
<br />
Again he presents no evidence other than empty rhetoric. If there is this sea of paedophile pornography we are all wallowing in then why aren't there more arrests and convictions?<br />
<br />
p204 His two porn experts are Shana Olfman and Gail Dines, Dines is apparently the best-known authority on the effects of pornography on women. That is nice but again both citations of evidence are for books and not for peer reviewed scholarship. Personally I have never heard of Dines at all and I follow a large number of sexologists and academic sex-perts on social media and she is never part of any conversations. In fact reading Dines' list of articles she does not have a single peer reviewed article in her career. All her writing is for newspapers and other public media. Olfman's scholarly c.v. is equally thin.<br />
<br />
p209 In November 2004, the US Senate held a committee hearing on "The Science of Pornography Addiction". Dr Judith Reisman, a prominent crusader against pornography, told the committee: "We now know that pornographic visual images imprint and alter the brain, triggering an instant, involuntary, but lasting, biochemical memory trail, arguably subverting the First Amendment by overriding the cognitive speech process. This is true of so-called 'soft-core' and 'hard-core' pornography. And once new neurochemical pathways are established they are difficult or impossible the delete."<br />
<br />
The problem is that Resiman is lying and this is an obviously bat-shit nuts statement. Affects the First Amendment by overriding cognitive speech? So I am no longer capable of free speech once I have been hypnotised by the evils of porn? It doesn't even make any sense when you write it down. She is a law Prof. She has no knowledge of neuroscience and the experiments she talks about do not exist and what has been done is neuro-science imaging of behaviour and adaptation is highly suspect. Basically this is all nonsense quoted as expert opinion.<br />
<br />
p210 He goes on to show that Resiman's testimony was shredded by real experts such as Dr Daniel Linz - so what he has done is presented something he knows to be bull-shit first and in a convincing way and then presents the refutation is less dynamic terms. This is typical of Thompson who uses rhetoric over reason and evidence. He takes a position and then tries to warp reality to fit what he wants. Up until this point it was merely annoying but this section of the book is appalling deceit. Regardless he cites Norman Doidge as being convinced that porn is as addictive as drugs. I might be convinced that Liverpool will win the Premiership next year or the New York Jets will win the Superbowl but it does not make it true or even likely.Andyhttp://www.blogger.com/profile/17784856869056663331noreply@blogger.com0tag:blogger.com,1999:blog-3504366798345365263.post-36677699447131960562012-09-27T13:46:00.000-07:002012-09-27T13:46:05.413-07:00The Common Lawyer - Mark Gimenez"Andy the tobacco companies kill a thousand people a day and have done for forty years.

But this paper is not cited again in the next 9 years and so this would seem to be a dead-end so convergence is still probable as suggested by Stewart.<br />
<b>Having a master gene would invalidate the idea of canalisation as it is too deterministic there would be no convergence in related populations, there would be no need for plasticity or evolvability. The system would be very rigid and not very robust to loss of master gene function.</b><br />
Fru gene controls make sexual response in fruit flies. This would be an example of a single gene and not a system of genes controlling a complex behaviour/trait. This would kill the need for a system and make selfish genes much more likely to exist. But this paper has not been cited again so it was probably a high level transcription factor required for activating many pathways.<br />
<br />
<b>Another physicist who sees futility where we do not need to. He worries that the Universe will end in about 13 billion years time and that this will be a waste of intelligent life. I think that if our descendants make it to 1 billion years that will be an outstanding success. At the minute we don't look like making another 100.</b><br />

p12 "now the heyday of reductionism has probably passed. Seemingly impenetrable obstacles have been encountered which cannot be solved by the simple reductionist approach."<br />
<br />
p82 "Sejnowski remarks, 'A lot of the details and organisational decisions in biology are historical accidents. You can't assume that nature took the simplest and most direct route to do something. Some features are remnants of some earlier stage of evolution, or it may be that some genes that happen to be around are commandeered for some other purposes.'"<br />

p333 "For 99% of human existence, we lived in small primitive, nomadic tribes that could economically support perhaps no more than fifty of so individuals.

"aggregation offers the possibility of 'personalised' learning systems that identify learner's skills levels and presents them with materials aimed at their current abilities."<br />
"the most commonly used electronic materials ... include articles, book chapters, illustrations and animations."<br />
"'Learning Objects' that could be plugged together to produce a course."<br />
"Learning objects have been rejected by Wiley (2000) as encouraging a simplistic view of learning resources, and a narrow view of education as transmission of blocks of content. He has proposed an alternative metaphor: that of a chemist combining atoms to form molecules."<br />
"not every resource can combine with every other."<br />
Indicators for useful Learning Objects would be "positive evaluation documentation, regular citations within the literature, and widespread adoption within accredited courses."<br />
"metadata describing their potential use."<br />
"much debate about who should produce metadata for Learning Objects."<br />
Resources should be durable and maintained e.g. content in an eJournal over material on an unsupported website.<br />
Quality Assured.<br />
Free from legal restrictions<br />
Formats that are accessible and ubiquitous<br />
Electronic formats or print.<br />
Engage the learner<br />
"reluctance among academics to submit authored resources to a digital repository ... insufficient reward (financial or kudos)."<br />
"that resources at appropriate cost will be adopted if other factors (for example accessibility of language) render them appealing to tutors and students."<br />
"The disadvantage of not being easily repurposed is apparently outweighed by the benefit of contextualisation or of saving time in aggregation."<br />
"Resources should be sufficiently small to be reusable, but large enough to ensure that tutors do not have to spend time aggregating large numbers of resources."<br />
"move away from a narrative presentation of information towards a more active use."<br />
"active learning resources and their sequencing within a learning design or lesson plan becomes more prominent, the profile of dynamic resources is likely to increase resources will need to show how they can be reused in a range of educational models or learning designs."<br />
"inverse relationship between resources being sufficiently large to be of educational value, while being small enough to reuse effectively."<br />
"embraces constructivist principles"<br />
"What may be a positive accessibility characteristic in one situation may be a barrier in another, even for the same subject area and teacher."<br />
"Currently many tutors start by focussing on content and may appreciate guidance in the choice of resource format, medium etc, as well as in consideration of educational design and learner activities through determining the suitability of resources for their teaching."<br />
"their use in context that is important."<br />

"when we leave a message in computer memory we feel an intense need for response."<br />
"Paradoxically, then speeding up and improving asynchronous exchanges causes unexpected distress. This explains why on-line communities place such an emphasis on active participation and are often critical of passive readers who are pejoratively called lurkers."<br />
"Flaming (the expression of uncensored emotions on-line) is viewed as a negative consequence of this feeling of liberation."<br />
"the idea of community implies bonds of sentiment that are not always necessary to effect online communication"<br />
"we must discover how the conference empowers its members to speak up and provokes others to reply."<br />
"Sharing of purpose among people who do not form a community but have accepted a common work or play as the context for an intense temporary relationship."<br />
"the social network designer - has emerged to solve the problems of organising and leading on-line groups."<br />
"try to get people on-line with the hope that once they connect something will happen. This approach to CMC leads to disappointing results."<br />
"Educational conferencing systems, for example, are fairly limited in their ability to handle mathematical symbols." Hiltz 1986.<br />
Created the idea of weaving "identifying the themes, making connections, 'indexing' the material mentally."<br />
"drawing together in a momentary synthesis that can serve as a starting point for the next round of debate."<br />
<br />
"The absence of tacit cues and coded objects strands participants in a contextual void that may leave them literally speechless."<br />
"The face-to-face meeting can also asynchronise the commencement of the on-line exercise through a ritualised initiation to the conference."<br />

If you wish to run a course that evolves in unpredictable ways, then you must make this clear to distant students from the start."<br />
"there is a great potential for abject confusion and worry from the students concerned over what they actually have to do and by when."<br />
"technology must not lead pedagogy"<br />
"If there is conscious planning then it is more likely that some developments will occur because the technology has something to offer in terms of efficiency or a broadening in the diversity of learning or contact routes and not so much simply because the technology is available."<br />
"why develop and offer the course at all? .... capture a new market .... delivery of the course more flexible and in that way capture new markets."<br />
"resist the temptation to provide on-line options to students on-campus purely as something additional. Instead try to introduce the use of technology with the intention of changing something, no matter how small."<br />
"the risk of swamping them with too much information should not be forgotten."<br />
"Will the students be able to access the course adequately?"<br />
"examine the learning outcomes of the course, linking these with the assessment criteria."<br />
"require a minimum hardware specification for any off-campus computer of internet connection."<br />
"think long and hard about the likely hardware and to a degree software resources that will be available to your students."<br />
"There will always be a handful of students that will not like working on-line or will be nervous of such work or feel intimidated by the use of a computer"<br />

The problem is the difference between perceived strategy as sensed amongst a populace or at least assumed and the real strategy which need not be the same.<br />
</span><span style="mso-bidi-language: HE;">Last year I received a remarkable letter from a professor at a university in a distant city, inviting me to an academic conference. I did not know the writer, and I couldn't even figure out from the name whether the writer was a man or a woman . The conference would involve long plane flights and a week from home. However, the letter of <span style="mso-spacerun: yes;"> </span>invitation was beautifully written<span style="color: #151516;">. </span>If the conference was going to be as beautifully organized, it might be exceptionally interesting.

In other words the effect of the ligand at first increases faster than its concentration. This behaviour is the more remarkable in that it appears to be characteristic of allosteric enzymes.In ordinary "classic" enzymes, on the contrary, the effect increases more slowly than the concentration p68.</blockquote>Foundation of the S-systems idea of Voit.<br />
<br />
<blockquote> For example: in state R the protein will be able to recognize and therefore to bind compound alpha at one site (but not compound beta), whereas in state T it will recognize and bind compound beta but not alpha. It follows that either compound will have the effect of stabilizing the protein in this or that of its two states, R or T, at the expense of the other; and that alpha and beta will be mutually antagonistic, since their respective interactions with the protein are mutually exclusive p70.</blockquote>This might be a way of getting an XOR relationship.<br />
<blockquote>There is no chemically necessary relationship between the fact that beta-galactosidase hydrolyzes beta-galatosides, and the fact that its biosynthesis is induced by the same compounds. Physiologically useful or "rational" this relationship is chemically arbitrary - "gratuitous" one might say. This fundamental concept of gratuity i.e. the independence, chemically speaking, between the function itself and the nature of the chemical systems controlling it - applies to allosteric enzymes... enabling an interaction, positive or negative, to come about between compounds without chemical affinity, and thereby eventually subordinating any reaction to the intervention of compounds that are chemically foreign and indifferent to this reaction. p77.</blockquote>This implies the generation of a hierarchy of levels of cybernetic control. It also suggests lots of possibilities for co-evolution of processes and regulation.<br />
<blockquote>only failure awaits attempts to reduce the properties of a very complex organisation to the "sum" of the properties of its parts. A most foolish and wrongheaded quarrel it is, merely testifying to the "holists" profound misappreciation of scientific method and of the crucial role analysis plays in it. If a Martian engineer were trying to understand one of our earthling computers, how far could he conceivably get were he, on principle, to refuse to dissect the basic electronic components which in the machine execute the operations of propositional algebra? If any one branch of molecular biology illustrates better than others the sterility of holist theses as against the cogency of analytical method, it is indeed the study of these microscopic cybernetic systems.. p 79.</blockquote>Monod is partly right and partly wrong the point is that the arrangement of the microscopic components is not embedded in the components themselves.<br />
<blockquote>And even though these analyses are not yet near to furnishing us with a complete description of the cybernetic system of the simplest cell, they tell us that, without exception, all the activities that contribute to the growth and multiplication of that cell are interconnected and intercontrolled directly or otherwise. On such a basis, but not that of a vague "general theory of systems," does it become possible for us to grasp in what very real sense the organism does effectively transcend physical laws - even while obeying them - this achieving at once the pursuit and fulfilment of its own purpose. </blockquote>This is just an attack on Bertalanffy who is referenced for General Systems Theory. It is not actually presenting any kind of alternative framework and it is also contradictory.Andyhttp://www.blogger.com/profile/17784856869056663331noreply@blogger.com0tag:blogger.com,1999:blog-3504366798345365263.post-91395621875673236252011-06-11T15:25:00.000-07:002011-06-11T15:25:58.083-07:00Chance and Necessity - Jacques Monod IIn the book he makes arguments for distinguishing signs of life from crystalline growth and other ways of creating order. A simpler approach is that of Lotka who said it was just a matter of definition and avoided the question all together. This is based on the idea of Paley and the watch-maker, showing that there must be design,<br />
<br />
<blockquote>The cornerstone of the scientific method is the postulate that nature is objective. In other words, the systematic denial that "true" knowledge can be got at by interpreting phenomena in terms of final causes - that is to say, of "purpose" ... <br />
<br />
Objectivity nevertheless obliges us to recognize the telenomic character of living organisms, to admit that in their structure and performance they act projectively - realize and pursue a purpose. p21-22.</blockquote>Is this true? Do we need purpose? It is indirect because selection requires the purpose of being able to deal with the environment.<br />
<blockquote>that invariance necessarily precedes teleonomy. Or, to be more explicit the Darwinian idea that the initial appearance, evolution, and steady refinement of ever more teleonomic structures are due to perturbations occurring in a structure which already possesses the property of invariance - hence is capable of preserving the effects of chance and thereby submitting them to the play of natural selection. p23-24.</blockquote>This is the point that the genome is separate and "invariant" as in it allows the random changes to be passed between generations. But this also echoes the ideas of Claude Bernard and that complex organisms carry their environment around with them and so are more robust to environmental changes. He accuses Elsasser and Polanyi of scientific vitalism which is unfair.Teilhard de Chardin is intellectually spineless (this is the use of the personal fallacy - attack the person and not the idea). Teilhard has evolution act on all components not just living things. This agrees with Lotka's definition of evolution but there is a genotype in living things.<br />
<br />
<b>Living things are robust, plastic and evolvable. So they have a balance between a defined shape/function and flexibility. They respond to the environment, yet they are separable pools of information. They are homeostatic but not closed.</b><br />
<b><br />
</b><br />
<blockquote>We know however (contrary to what Laplace believed, and after him the science and "materialist" philosophy of the 19th century) that these predictions could be no more than statistical.<br />
In a general manner the theory would anticipate the existence, the properties, the interrelations of certain classes of objects or events, but would obviously not be able to foresee the existence or the distinctive character of any particular object or event. p43.</blockquote><b>This is the point about biology being a phenomenological subject and that it might not have an fundamental predictive laws.</b><br />
<blockquote>Plainly enough, the functional coherence of so complex a chemical machine, which is autonomous as well calls for a cybernetic system governing and controlling the chemical activity at numerous points. p45.</blockquote><blockquote>This specificity is two-fold:<br />
<ol><li>Each enzyme catalyses but one type of reaction.</li>
<li>Among the sometimes very numerous compounds in the organism susceptible of undergoing that type of reaction, the enzyme, as a general rule, is active in regard to only one.<br />
</li>

We have lost our ability to put things together. We have got deeper and narrower to an extent that we can no longer link ideas in an interdisciplinary way and this limits our reasoning and our "wisdom". It leads to isolated decision making that will always create unforseen consequences, at a time when we can least afford it. <br/><br/>The news today had an example which was the relationship between obesity and diet and exercise. The new research suggests that first you tackle diet and eating as if you focus on increasing acticvity and exercise you have limited success because once you have the extra pounds you are less keen to be active. This is when the foolish Secretary of State for Health says that diet should not be governed centrally but that people should take their own responsibility regardless of evidence showing legislation of the food industry in France and Denmark has reduced obesity. He also forgets the experiences of two world wars and particularly of rationing that improved the diet of millions of people, who had been almost starving before-hand.<br/><br/><h3>The Perfect Storm</h3>This chapter is focussed on his ideas about the need for non-centralised managements and the weaknesses of having a centralised government that uses a command-and-control structure which cannot plan for every eventuality. This does not allow for local corrections to problems that arise. The examples he takes come from the Nobel Prize winner Hayek. These have been confirmed recently by the result of complex systems analysis.<br/><br/>This seems to me analogous to the gaze heuristic. We do not calculate the trajectory of a ball, we look to guide it into our hands by minor corrections that bring us to the final solution. This means a much more pragamatic and localised structure to problem solving. So government only sets the strategic goals - the actual implementation is carried out globally.<br/><br/>There are also practical links with the problems we face in high throughput biology. We are losing the specialised "local" biological knowledge that we used to have in small-scale laboratory experiments, where people were very familiar with the genes they were studying and so there was lots of know-how that did not enter the literature. This was particularly important in the case of genome annotations and so the result was the creation of the <a href='http://stein.cshl.org/das/'>DAS annotation system</a>. Which never seemed to make the headway that was needed. Good idea but just too complicated to be used - this is a limitation of the semantic web and of creating perfect database schema. They manage knowledge perfectly but exclude the user and the requirements of the specifications change too often.

Like Descartes, we must maintain the dignity of Man by treating him on a basis entirely different from that on which we treat the lower animals. Evolution and the origin of the species are a desecration of human values; and as the earlier Darwinians found, to entertain these ideas is very dangerous for the scientist in a world fundamentally suspicious of science.<br />But even in the field of science, it is perilous to run counter to the accepted tables of precedence. On no account is it permissible to mention living beings and machines in the same breath. Living beings are living beings in all their parts; while machines are made of metals and other unorganised substances, with no fine structure relevant to their purposive or quasi-purposive function. Physics - or so it is generally supposed - takes no account of purpose; and the emergence of life is something totally new." p14-15.<br /><br />"The learning of the individual is a process that occurs in the life of the individual, in ontology. Biological reproduction is a phenomenon that occurs in the life of the race, in phylogeny, but the race learns even as the individual does. Darwinian natural selection is a kind of racial learning, which operates within the conditions imposed by the reproduction of the individual" p21.<br /><br />"Thus if we do not lose ourselves in the dogmas of omnipotence and omniscience, the conflict between God and the Devil is a real conflict, and God is something less than absolutely omnipotent. He is actually engaged in a conflict with his creature in which he may very well lose the game. And yet his creature is made by him according to his own free will, and would seem to derive all its possibility of action from God himself. Can God play a significant game with his own creature? Can any creator, even a limited one, play a significant game with his own creature." p24.<br /><br />"However, even living systems are not (in all probability) living below the molecular level. Furthermore, with all the differences between living systems and the usual mechanical ones, it is presumptuous to deny that systems of the one sort may throw light upon systems of the other. One respect in which this may well be the case is that of the mutual convertibility of spatial and functional structure, on the one hand, and of messages in time, on the other. The template account of reproduction is manifestly not the whole story. There must be some communication between the molecules of genes and the residues to be found in the nutrient fluid, and this communication must have a dynamics. It is quite in the spirit of modern physics to suppose that field phenomena of a radiative nature mediate the dynamics of such communication. It will not do to state categorically that the processes of reproduction in the machine and in the living being have nothing in common.<br />Pronouncements of this kind often seem to cautious and conservative minds to be less risky than rash statements of analogy. However, if it is dangerous to assert an analogy on insufficient evidence, it is equally dangerous to reject one without proof of its inconsequentialness. Intellectual honesty is not the same thing as the refusal to assume an intellectual risk, and the refusal even to consider the new and emotionally disturbing has no particular ethical merit." p51-52.<br /><br />"The orthodox Christian and the sorcerer agree that after the miracle of the consecration of the Host is performed, the Divine Elements are capable of performing further miracles. They agree moreover that the miracle of transubstantiation can be performed only by a duly ordained priest. Furthermore, they agree that such a priest can never lose the power to perform the miracle, though if he is unfrocked he performs it at the sure peril of damnation.<br />Under these postulates, what is more natural than that some soul, damned but ingenious, should have hit upon the idea of laying his hold on the magic Host and using its powers for his personal advantage. It is here, and not in any ungodly orgies, that the central sin of the Black Mass consists. The magic of the Host is intrinsically good: its perversion to other ends than the Greater Glory of God is a deadly sin.<br />This was the sin which the Bible attributes to Simon Magus, for bargaining with Saint Paul for the miraculous powers of the Christians. I can well imagine the puzzled aggrievement of the poor man when he discovered that these powers were not for sale, and that Paul refused to accept what was, in Simon's mind, an honourable, acceptable and natural bargain. It is an attitude that most of us have encountered when we have declined to sell an invention at the really flattering terms offered us by a modern captain of industry.<br />Be that as it may, Christianity has always considered simony as a sin, that is, the buying and selling of the offices of the Church and the supernatural powers implied therein. Dante indeed places it among the worst of sins, and consigns to the bottom of his Hell some of the most notorious practitioners of simony of his own times. However, simony was a besetting sin of the highly ecclesiastical world in which Dante lived, and is of course extinct in the more rationalistic and rational world of the present day.<br />It is extinct! It is extinct. Is it extinct? Perhaps the powers of the age of the machine are not truly supernatural, but at least they seem beyond the ordinary course of nature to the man in the street. Perhaps we no longer interpret our duty as obliging us to devote these great powers to the greater glory of God, but it still seems improper to us to devote them to vain or selfish purposes. There is a sin, which consists of using the magic of modern automisation to further personal profit or let loose the apocalyptic terrors of nuclear warfare. If this sin is to have a name, let that name be Simony or Sorcery." p57-58.<br /><br />"I am most familiar with gadget worshippers in my own world, with its slogans of free enterprise and the profit-motive economy. They can and do exist in that through-the -looking-glass world where the slogans are the dictatorship of the proletariat and Marxism and communism. Power and the search for power are unfortunately realities that can assume many garbs. Of the devoted priests of power, there are many who regard with impatience the limitations of mankind, and in particular the limitation consisting in man's undependability and unpredictability. You may know a mastermind of this type by the subordinates he chooses. They are meek, self-effacing, and wholly at his disposal; and on account of this, are generally ineffective when they once cease to be limbs at the disposal of his brain. They are capable of great industry but of little independent initiative - the chamberlains of the harem of ideas to which their Sultan is wedded." p59.<br /><br />"The gadget minded people often have the illusion that a highly automated world will make smaller claims in human ingenuity than does the present one and will take over from us our need for difficult thinking, as a Roman slave who was also a Greek philosopher might have done for his master. This is palpably false. A goal-seeking mechanism will not necessarily seek our goals unless we design it for that purpose, and in that designing we must foresee all steps of the process for which it is designed, instead of exercising a tentative foresight which goes up to a certain point, and can continued from that point on as new difficulties arise. The penalties for errors of foresight, great as they are now, will be enormously increased as automation comes into its full use." p68.<br /><br />"It is unthinkable that all lives should be prolonged in an indiscriminate way. If, however, there exists the possibility of indefinite prolongation, the termination of a life or even the refusal or neglect to prolong it involves a moral decision of the doctors. What will then become of the traditional prestige of the medical profession as priests of the battle against death and as ministers of mercy? I will grant that there are cases even at present when doctors qualify this mission of theirs and decide not to prolong a useless and miserable life. They will often refuse to tie the umbilical cord of a monster; or when an old man suffering from an inoperable cancer falls victim to the "old man's friend", hypostatic pneumonia, they will grant him the easier death rather than exact from him the last measure of pain to which survival will condemn him. Most often this is dome quietly and decently, and it is only when some incontinent fool blabs the secret that the courts and the papers are full of the talk of "euthanasia."" p 72.<br /><br />"No, the future offers very little hope for those who expect that our new mechanical slaves will offer us a world in which we may rest from thinking. Help us they may, but at the cost of supreme demands upon our honesty and our intelligence. The world of the future will be an ever more demanding struggle against the limitations of our intelligence, not a comfortable hammock in which we can lie down to be waited upon by our robot slaves." p74.<br /><br />"Homeostasis, whether for the individual or the race, is something of which the very basis must sooner or later be reconsidered. This means for example as I have said in an article for Voprosy Filosofii in Moscow, that although science is an important contribution to the homeostasis of the community, it is a contribution the basis of which must be assessed anew every generation or so. Here let me remark that both the Eastern and Western homeostasis of the present day is being made with the intention of fixing permanently the concepts of a period now long past. Marx lived in the middle of the first industrial revolution, and we are now well into the second one. Adam Smith belongs to a still earlier and more obsolete phase of the first industrial revolution. Permanent homeostasis of society cannot be made on a rigid assumption of a complete permanence of Marxism, nor can it be made on a similar assumption concerning a standardised concept of free enterprise and the profit motive. It is not the form of rigidity that is particularly deadly so much as rigidity itself, whatever the form." p86.<br /><br />"Here some recent work of Mandlebrot is much to the point. He has shown that the intimate way in which the commodity market is both theoretically and practically subject to random fluctuations arriving from the very contemplation of its own irregularities is something much wilder and much deeper than has been suppose, and that the usual continuous approximations to the dynamics of the market must be applied with much more caution than has been the case, or not at all." p93.<br /><br /><i><br />Written in 1963 at the height of the Cold War during a time when the threat of nuclear war hung over everyone. </i> <br /><br />Chapman and Hall, London, 1964.</div>Andyhttp://www.blogger.com/profile/17784856869056663331noreply@blogger.com0tag:blogger.com,1999:blog-3504366798345365263.post-76902889566147429212010-06-29T15:20:00.001-07:002010-06-29T15:20:12.783-07:00The Thief of Time<div xmlns='http://www.w3.org/1999/xhtml'>This is a great book as it covers chaos and emergence and what it actually means in terms of life. How life breaks all the rules, how the order of life arises from the chaos of the universe and how as a consequence life exists on the margins of the possible as a fragile bubble of existence that vanishes in an instant in the universal scale of things. I don’t know if that is depressing or optimistic.<br /><br />The irony of the auditors is that they represent the accounting of the universe that hates the untidiness if life but they also represent the extreme of reductionist science. Trying to understand art and beauty by taking it apart and examining it a molecule at a time. Sometimes science forgets that you need to look at the whole and that the whole is more than the sum of the parts even if it shouldn’t be as Susan realises.</div>Andyhttp://www.blogger.com/profile/17784856869056663331noreply@blogger.com0tag:blogger.com,1999:blog-3504366798345365263.post-16444764571906982732010-06-29T15:18:00.001-07:002010-06-29T15:18:36.778-07:00Why Sex is Fun - Jared Diamond<div xmlns='http://www.w3.org/1999/xhtml'>"Becoming a male is a prolonged, uneasy, and risky venture; it is a kind of struggle against inherent trends toward femaleness." A. Jost quoted p46 WSIF<br /><br />Chauvinists might go further and hail becoming a man as heroic and becoming a woman as the easy fallback position. Conversely, one might regard womanhood as the natural state of humanity, with men just a pathological aberration that regrettably must be tolerated as the price for making more women. I prefer merely to acknowledge that a Y chromosome switches gonad development from the ovarian path to the testicular path, and to draw no metaphysical conclusions. ibid p46<br /><br />from evolution of mating systems amongst the primates he concludes;<br />"We thus conclude that promiscuity or harems, not monogamy, is the mating system that leads to concealed ovulation. This is the conclusion predicted by the many fathers theory. It doesn’t agree with the daddy-at-home theory." p89<br /><br />What about mixed strategies aren’t these even better? Many fathers and daddy-at-home. Convince many that they may be the father and yet give one the strong belief that he can maintain monogamy by remaining at home in close proximity. The necessary falsehood of monogamy is the most useful strategy as both both parties have their cake and eat it. They both pretend monogamy is good while cheating like mad. The problem is the difference between perceived strategy as sensed amongst a populace or at least assumed and the real strategy which need not be the same.<br /><br />Last year I received a remarkable letter from a professor at a university in a distant city, inviting me to an academic conference. I did not know the writer, and I couldn’t even figure out from the name whether the writer was a man or a woman. The conference would involve long plane flights and a week from home. However, the letter of invitation was beautifully written. If the conference was going to be as beautifully organized, it might be exceptionally interesting. With some ambivalence because of the time commitment, I accepted.<br />My ambivalence vanished when I arrived at the conference, which turned out to be every bit as interesting as I had anticipated. In addition, much effort had been made to arrange outside activities for me, including shopping, bird watching, banquets, and tours of arcaelogical sites. The professor behind this masterpiece of organization and the original virtuoso letter proved to be a woman. In addition to giving a brilliant lecture at the conference and being a very pleasant person, she was among the most stunningly beautiful women I ever met.<br /><br />On one of the shopping trips that my hostess arranged, I bought several presents for my wife. The student who had been sent along as my guide evidently reported these purchases to my hostess, because she commented on them when I sat next to her at the conference banquet. To my astonishment, she told me, "My husband never buys me any presents!" She had formerly bought presents for him but eventually stopped when he never reciprocated.<br />Someone across the table then asked me about my fieldwork on birds of paradise in New Guinea. I explained that male birds of paradise provide no help in rearing the nestlings but instead devote their time to trying to seduce as many females as possible. Surprising me again, my hostess burst out, "Just like men!" She explained that her own husband was much better than most men, because he encouraged her career aspirations. However, he spent most evenings with other men from his office, watched television while at home on the weekend, and avoided helping with the household and their two children. She had repeatedly asked him to help: she finally gave up and hired a housekeeper. There is, of course, nothing unusual about this story. It stands out in my mind only because this woman was so beautiful, nice, and talented that one might naively have expected the man who chose to marry her to have remained interested in spending time with her. ibid p95-96<br /><br />This is so sad she should ditch the fool - it is annoying when brilliant women are wasted on neanderthal man.<br /><br />Now compare the reproductive outputs of men pursuing the two different hunting strategies that Hawkes terms the 'provider' strategy and the 'show-off' startegy. The provider hunts for foods yielding moderately high returns with high predictability, such as palm starch and rats. The show-off hunts for big animals; by scoring only occasional bonanzas amod many more days of empty bags, his mean return is lower. The provider brings home on the average the most food for his wife and kids, although he never acquires anough of a surplus to feed anyone else. The sho-off on the average brings less food to his wife and kids but does occasionally have lots of meat to share with others.<br /><br />Obviously, if a woman gauges her genetic interests by the number of children whom she can rear to maturity , that’s a function of how much food she can provide them, so she is best off marrying a provider. But she is further well served by having show-offs as neighbours, with whom she can trade occasional adulterous sex for extra meat supplies for herself and her kids. The whole tribe also likes a show-off because of the occasional bonanzas that he brings home for sharing. p105<br /><br />Physiology and molecular biology can do no more than identify proximate mechanisms; only evolutionary biology can provide ultimate causal explanations. As one simple example, the proximate reason why so called poison-dart frogs are poisonous is that they secrete a lethal chemical named batrachotoxin. But the molecular biological mechanism for the frog’s poisonousness could be considered an unimportant detail because many other poisonous chemicals could have worked equally well. The ultimate causal explanation is that poison-dart frogs evolved poisonous chemicals because they are small, otherwise defenceless animals that would be easy prey for predators if they were not protected by poison p116-117. <br /><br />Consider SJ Gould and nipples the clitoris etc. and also Plato on levels of cause mol. biol. = material and evo. biol. gives another level of cause but probably not the level of final cause.</div>Andyhttp://www.blogger.com/profile/17784856869056663331noreply@blogger.com0
