The Flight from Science & Reason

Recently on my half term break I finally managed to pluck up the courage to read The Flight from Science and Reason, a collection of essays by scientists on the pseudosciences, which were attacking science quite vigorously.

Previously I've used it for the occasional essay, such as this one, about James Trefil's contribution, however, I've never read it from cover to cover which is a pity. This time though, I managed to cover the whole book.

One of the things that struck me is the lack of some issues which skeptics seem to miss. Afrocentrism and Feminist criticism of science are one of two areas. After reading one article on ecofeminism, I turned to the net and started analysing the sources on ecofeminism, the belief that it is a patriachal society which is destroying the environment.

After a bit of searching, I came across this article. What is Ecofeminism anyway?

The article is by Catherine and Colleen McGuire.

Lets start out with the basics shall we?

As a practice, ecofeminism is as ancient as our species. Many ecofeminists believe that the nature of our species is more in line with how we lived prior to the debut of written history. This period, extending back as far as 250,000 years ago, was a time when cooperation—not competition—was valued and necessary for species survival. New archeological discoveries of early civilizations in Mesopotamia yield a vast array of evidence that an egalitarian lifestyle and a unity with nature were prevalent among ancient peoples of those regions. Theories supporting territoriality, survival of the fittest, or man the great hunter are appearing to be inadequate, if not false.
Somehow they've managed to make a strawman of archaeology here. The fact that humans are both hunters and gatherers has been evident throughout our history. This seems romanticised. What's next? Should we not be blamed for the extinction of the Neanderthal?

Women's spirituality, such as goddess spirituality, has likewise left a distinct imprint on ecofeminism. Alienated by male-centered hierarchical religions, Westerners—especially women—are increasingly turning to spiritualities which validate female divineness and equality. Many people are also (re)embracing shamanism, the ancient, nature-based spirituality that was originally practiced by all humans everywhere, and preceded female-centric spirituality.
Here we have a bold claim. Ecofeminists are spiritual. This should set anyone's woo meter blinking. This was a major criticism made by authors in FfS&R, in that eco-feminism concentrated on this spirituality reference rather than the cold hard facts.

Although there is no one "correct" ecofeminism, most ecofeminists would agree with the core precept that the domination of women and the domination of nature are fundamentally connected. In other words, violence against Mother Earth came to be intertwined with an emerging urge to subdue and control women. These twin oppressions were created and are perpetuated by an ideology called patriarchy. Pinpointing the origins of patriarchal thought and practice is as elusive as trying to identify who invented the wheel. Suffice it to say, Western patriarchy arose roughly 5,000 years ago and has discombobulated our planet ever since.
So all women care for nature? What about the men? If there is one thing I hate is a reverse sexist position that some feminists produce. Note though the woolly claims. No substance and nothing to tie into the archaeological record.

The Western patriarchal belief system also places higher value on linear, mechanistic, analytical, and rational qualities. The intuitive, emotional, anarchic, and earthy are negatively perceived as passive, weak, irrational—and female. Nature is paradoxically considered inert, dead mass and a wild, chaotic force. By either reckoning, nature is to be dominated and harnessed for human ends. By extension, the patriarchal mind objectifies, controls, and devalues all that is labeled "female."
I suspect there is a sly attack on science there. Last time I checked, it was a male scientist who came up with some of the best points about nature, Darwin. To quote him:

There is a grandeur in this view of life.
Both women and men are socialized to accept these man-made values. Although men, too, are harmed by patriarchal practices, they nonetheless benefit from them at the expense of women. For example, men own 99% of the world's property while women perform two-thirds of the world's labor. Another example: men rarely shoulder the physical, social, political, or psychological consequences of the experience of rape (unless sexually abused as children or as prison inmates). It is women of all ages who are burdened with the psychic fear induced by a climate in which the threat of sexual violation looms like a distant rain cloud: sometimes miles away, other times hovering right over us.



Wow, a fear speech. I think what is confusing is that later on we get this claim:

Attacking patriarchy is not the same as male-bashing. The masculine sex is not "the enemy." Rather, patriarchy is a particular way of thinking whose practitioners can be of any gender.
OK, this is a separate section and might not have been written by the McGuires, however, its clear that it goes against what they say. Furthermore, they also say:

We as a species are in an arrested state of adolescence as insecure egos (mostly male)
A few more points:


  • Overpopulation is inevitable when the control of reproduction is wrested away from women, and educational and contraceptive resources are not broadly disseminated.
  • In ancient times, women exercised exclusive self-determination over their bodies. Our foresisters had extensive holistic knowledge about birth control, abortion, birthing, and other gynecological concerns.

  • Maaaaaaaaaggggggggic eh?

    I can keep on, but its obvious that from points made by articles such as this, eco-feminism is merely a front for another form of reality denial. This romanticised idea of history (or should that be herstory?) and the rejection of logic makes these a topic of skepticism. The only problem is that as a member of the gender with the cursed chromosome, my viewpoint is probably patrichal and biased, despite my private beliefs on equality. Furthermore, it is disrespectful towards those who work against climate change by confusing the issue with woo and pseudoscience/ the rejection of science.

    This is not real...

    Good evening and I thought I would start this post with a reminder that the preceeding article is not real. This is due to reports that yet again someone has actually mistaken my blog for the real thing. I can definitely assure people that Gavin Schofield is not in a coma although I do find the fact he described stomach pumps as rocking slightly disturbing, however, this might be due to excessive alcohol consumption after the event if this is true.

    I've been following the 10:23 campaign recently and it looks very interesting.

    Possibly with the combination of the recession and the campaign, MPs are expected to publish a report concluding that homeopathic remedies should not be on the NHS. I think this is a good idea and in the words of Professor Ernst may make pharmacists like Boots, healthcare professionals, not the shop keepers.

    The Guardian has an article by Martin Robbins which outlines his reasoning behind joining the campaign and the evidence which shows the problems of homeopathy. Another article to read on this matter is Ben Goldacre's discussion of his Lancet article in 2007.

    In all I hope this campaign has had the impact it intended. For further information please visit 10:23 Campaign Website.

    500 Skeptics hospitalised in overdose horror

    Journal of Imaginary Sciences, 2010, Vol 31

    10:23 Campaign is marred by hospitalisations

    Yesterday, tragedy struck as 500 protestors against homeopathy were rushed to hospital after suffering from the massive overdose they took.

    The 10:23 campaign was designed to protest against the selling of homeopathic remedies at the pharmaceutical store, Boots. In order to demonstrate that these pills were apparently non-functional, the campaign managers suggested that the protestors should down a bottle of homeopathic pills each at 10:23, a symbolic note of the Avagadro's constant, the number of atoms that make up one mole.

    The campaign was organised by Michael Marshall, head of the Merseyside Skeptics Society, a branch of Skeptics in the Pub and was carried out, outside Boots stores across the country in Edinburgh, Liverpool, Manchester, Leeds, etc.


    However, tragedy struck, as a few minutes after the videos were took, the protestors started to feel unwell.

    "Well a few minutes after I took the medicine, I started to feel very nauseous, and promptly threw up. Thankfully I did because it stopped me from absorbing most of the effects" one protestor said.

    Currently, Gavin Schofield, leader of the Greater Manchester Skeptics as seen on the video, is reported to be in hospital in a coma, whilst Michael Marshall, the head of the campagin is said to be recovering in his bed, but still in a critical condition.

    Paula Ross, chief executive of the Society of Homeopaths, stated:

    "This ill-advised stunt shows the dangers of skeptics becoming closed-minded in the effects of alternative medicines. I feel sorry that people are stupid enough that they overdosed on these medicines in an attempt to prove these ineffective. I hope the survivors will have more sense in future."

    Ben Goldacre, author of the book Bad Science, doctor and journalist for the Guardian column "Bad Science" commented:

    "I've commented several times on homeopathy being ineffective from clinical trials. After seeing the results first hand from yesterday I am shocked I ever thought homeopathy was harmless."

    James Randi, the famous magician cum skeptic has also been criticised for his part in this misadventure. Years ago, Randi was noted for including in his act, a description of how he overdosed on a bottle of homeopathy pills in front of an audience and suffered no side effects. This account, along with the later attempts by Belgian Skeptics is thought to be the inspiration for Michael Marshall's foolish attempt.

    Podcast next week

    Hi,

    I'm currently preparing a podcast to be posted next week. It will explore the genetic evidence for Human evolution in about 15 minutes and try and show how scientists have constructed phylogenetic trees in accordance to the evidence. I may also include another podcast detailing the fossil evidence for human evolution too.

    See you then.

    Human Evolution 101

    In this series I hope to point out the specific areas which show that Humans evolved. In this I will be covering the fossil record, showing that humans evolved from a common ancestor with chimps.

    As pointed out earlier, there are a number of fossils which show Evolution between humans and our last common ancestor with chimps.

    Here we see a number of fossils from the hominins. Names are below:



    * (A) Pan troglodytes, chimpanzee, modern
    * (B) Australopithecus africanus, STS 5, 2.6 My
    * (C) Australopithecus africanus, STS 71, 2.5 My
    * (D) Homo habilis, KNM-ER 1813, 1.9 My
    * (E) Homo habilis, OH24, 1.8 My
    * (F) Homo rudolfensis, KNM-ER 1470, 1.8 My
    * (G) Homo erectus, Dmanisi cranium D2700, 1.75 My
    * (H) Homo ergaster (early H. erectus), KNM-ER 3733, 1.75 My
    * (I) Homo heidelbergensis, "Rhodesia man," 300,000 - 125,000 y
    * (J) Homo sapiens neanderthalensis, La Ferrassie 1, 70,000 y
    * (K) Homo sapiens neanderthalensis, La Chappelle-aux-Saints, 60,000 y
    * (L) Homo sapiens neanderthalensis, Le Moustier, 45,000 y
    * (M) Homo sapiens sapiens, Cro-Magnon I, 30,000 y
    * (N) Homo sapiens sapiens, modern

    Notice how they start to look like us as we go forward in time? The increase in brain size also confirms this.



    The picture includes the relevant study as well.

    Now we know that all ardipithecines, australopithecines and the ones from the genus homo are bipedal. This can be deduced from the fact that the structure of bone in their femur shows the cancellous bone to be adapted for bipedal walking according to Wolff's Law. Another piece of evidence is the foramen magnum. In all of these fossils, the foramen magnum is more vertical than chimps, highlighting that these are bipedal animals.

    For more information on the subject of bipedalism read these papers:

    Wynn, T., 2002, Archaeology and cognitive evolution, Behavioural and Brain Sciences 25, 3: 389-402

    If human evolution is false then we would not see links between these species, which we do as I have many more papers which also detailed the cognitive evolution, showing how society has evolved in co-existence with the physical evolution of humans.

    Another conundrum which Evolution solved is Lucy's hand. Chimps and gorillas have a feature in their wrist which allows them to do a form of quadrapedal walking called knuckle walking. It locks the wrist so that it cannot bend back like ours can, evidenced by Smith fractures. Now somewhere, we have lost that trait in our ancestry. Strait, et al, in an anatomical examination of Lucy the Australopithecine, found that these hominins have it whilst later ones such as Homo erectus do not!

    Paper is here

    This provides proof that this species is not a chimp nor humans as it is bipedal and has a feature only found in other Great Apes excluding ourselves!

    Furthermore, if Evolution was false, we would not find this transition in the fossil record. Instead of this gradual increase in brain size, etc, we would see fossils like Homo erectus in the wrong place, a typical "Precambrian Rabbit problem." This shows that the fossil record supports Human Evolution.

    Next week, Genetics!

    Any papers you want to read? Please leave a message and I'll get back to you.
    Hello again,

    Firstly I would like to draw people's attention to this campaign.

    The 10:23 Campaign

    I've signed the petition, and just for you lucky people, I'm going to link back my favourite homeopathy article from when I started this blog. Homeopathy Kills

    Over on Greater Manchester Skeptics, Gav brought my attention to it. I recommend signing it as it as Chemists such as Boots shouldn't really have expensive crap on their shelves, it should be real medicines.

    Also, I did this overview of Human Evolution, 101, setting out the reasons why experts know that Human Evolution happened from the fossil record. Next week, I'll discuss the genetics......
