Implying that - it is more accurate? or better in some unspecified way? if it is "dialectical" by this definition? Adam, what exactly is the point of approaching Origin [or anything] in this way? iii) No examples of this, as far as I can see. Why ? . . . The obvious example of negation of negation in society is the role of the working class under capitalism - in raising itself to the position of the ruling class ( negation of the capitalists ) it abolishes itself as a working class ( negation of the working class, ie negation of the negation ) and brings about something qualititively new on the basis of the old. First point about this example : it works at a very high level of complexity - atoms - organic beings - animals - humans - classes - revolutionary change in relations between classes Second point - it works by dividing relations between classes into types. It's as if Darwin had introduced a succession of types of ecology, and explained how natural selection moved from one type of ecology to another. Such things DO seem to happen in evolutionary history - replacement of the dinasaurs by mammals, single cell organism by multi cellular, mass extinctions, and huge differentiation of successor species. Hmm . . . 3. Darwin points out that chemical and physical laws are of more and more importance the lower down the scale of complexity you go. We can add that natural selection does not apply to humans either, as his basic condition for the operation of natural selection, that we produce more many many more young than we can feed, does not hold. ( Negation of the negation ? stretching it a bit . . . ). The definition of limits of applicability of your own theory seems really cool . . . 4. Darwin talks about the Law of Divergence of Character, and the vague feeling amongst naturalists that there is a progression in evolution. I know any idea that evolution has a direction allows god in by the back door, but a tendency to complexity in evolution does emperically exist, and Darwin himself recognises this. 5. The chapter on Hybrids and Crossing seems particularly weak - unlike his knowledge of geology, which though limited, was sufficient for his purposes ( I assume he is more or less right about fossils usually being found in slowly subsiding strata ). I assume this was because genetics hadn't got going properly in his time . . . could Lisa expand on this . . . ? Adam. ------------------------------ From: Adam Rose <adam-AT-pmel.com> Date: Wed, 14 Aug 96 08:08:58 GMT I was listening to a tape on the Dialectics of Nature by Paul McGarr at Marxism 96. During it, he explains the process of focusing on a small part of nature, abstracting general rules >from this small part of nature, and then explaining why specific cases deviate from these general rules ... He goes on to argue that these rules, however general they seem, in fact only have limited validity. This is for two reasons : firstly, they are by definition abstractions of a small part of nature, secondly, even this small part of nature itself has a history. LR: So, how does that make generalization invalid? AR: ... He [Darwin] has uncovered the laws of development of life - but he does not ( cannot ) explain how and why life first developed. For instance, he ( tentatively, admittedly ) puts forward a rule which suggests that there are always more or less the same number of species at any one time. He also explains that were there are no mammals, other animals have taken their place - tortoises in the Galapagos islands, large flightless birds in pre human New Zealand. These rules are probably true, given a certain type of underlying ecology, given a starting point similar to most of geologically recent history. But as life was developing, it simply cannot have been true - in the beginning, there must have been one, or at most a very few, single celled organisms. LR: I don't think of these as "rules". What do you think he meant by that? Non-theory types of and before his time used "rule" and "law" for observed trends and tendencies, and sometimes inferred some underlying process or mechanism, even tho it was the "mind of god" or "nature's beneficience" or something like that. But Darwin offered a NatSel explanation of _why_ these patterns occurred, didn't he? Or what was his point in talking about replacements for mammals? [Which edition of Origin are you using, btw?] And of course it all started with unicellulars. I don't recall if he spelled it out in Origin, but I think that the vision of everything "descending with modification" from other species, the connection of all living things to one geneological tree, this was a mind-boggling insight, especially given the lack of any knowledge of Mendel and modern genetics. Are you saying that he _should_ have included a theory of the origin of life in his work? Why? AR: But neither [Newton and Darwin] give us a history of the circumstances which give rise to their laws in the way that Marx and Engels do for human society. LR: What do you mean, "give rise to" a law? First off, "law" is so archaic in science I can hardly think of that term at all. Second, the nature of natural selection is that is is contingent upon specific circumstances. When these occur, natural selection occurs. Period. Where do you get a "law" out of that? AR: He cannot tell us why the law of Natural Selection started, and why it no longer applies to humans, even though it gave rise to humans. LR: The "law of NS" didn't start at any particular time, other than with the origin of life. There is no _why_ it started, it is simply the result of certain circumstances occurring. I address its application to humans briefly, below. I think Rahul got it right, that Darwin didn't try to explain the origins of the first life because it seemed impossible given the state of science at the time. Actually he was pretty busy with this other little thing - I mean, it was rather ambitious to try to explain the origin of new species, one or more from an earlier one. Did he do a pretty good job of it? I think so, even tho he did it without being very "dialectical", apparently.

AR: ... I was just saying that the relative "historicalness" of the three sets of theories [Newton, Darwin, Marx] seems to have a relationship to their relative "dialecticalness". ... LR: But Adam, why should we care about their "dialecticalness" ?? And BTW, NS _does_ apply to humans. Are you saying that Darwin said it doesn't, or is that your own opinion? Don't just think of industrial elite humans, think of the whole of human experience in the last 30,000 years. The more general picture of relative reproductive success does not strictly require "many more births" than can be supported. Darwin also addressed sexual selection, for instance. But there is good evidence for "excess" births in many cases as well. Lisa p.s. Darwin's second edition was better, clearer, unpressured by all the opposition, I've been told. [Haven't got around to comparing them, myself.] Sixth edition is most commonly used today, but it contains a lot of accomodation to other claims that evolution had to work faster than by pure NS alone, due to the allegedly short life of the planet. Things are different now. We know the earth is a lot older than was thought then. --- from list marxism2-AT-lists.village.virginia.edu ---
