RE: [xmca] Plasticity and Physiotherapy

Hi Andy,
 
What a spectacular  article is that of Kurt Lewin!!! Today i have done nothing else than reading and try to grasp its depth..I am trully impressed from his genius comprehension of epistemology as such and how he manages to explain all the paradigms of psychology existed in his time in a general epistemological framework. He was obviously a scholar of the scope of Vygotsky and Luria, there is no  doubt about that. 
 
But i am just wondering, the time that he wrote those amazing things had he any contact with Vygotsky?

The article by Tobias Rees which Elizabeth forwarded is very
interesting. It looks at the proposition that adhering to a theory of
neuroscience implies adherence to an ethic. Presumably any science.
Einstein spent more time advocating for World Government than he did
advocating for a Unified Theory of Physics. But I am still not satisfied
that I understand where this blindness to alternative theories came from
and I think Activity Theory is an approach which can help us here. Rees
tell us:

    "the various imaging techniques at the core of cognitive
    neuroscience-essentially a fusion of cognitive psychology and
    neurobiology-are all grounded in the assumption that the brain is
    divided into discrete, function-specific regions that are made up of
    function-specific synaptic circuits. For this focus to be
    meaningful, one has to presuppose what all of neuroscience
    presupposed throughout the 20th century: (1) that the brain is a
    fully developed and, hence, fixed and immutable structure; (2) that
    this structure is organized in (of course, equally immutable)
    function-specific circuits; (3) that synapses-given that the rest of
    the structure does not change its form-are its main functional
    elements; and (4) that the language of the brain-be it chemical,
    electrical, or genetic-is machinelike." (p. 155)

So the implication is that the idea of an unchanging brain was necessary
to make sense of a whole set of practices by means of which the brain
was investigated. Mmebership of that project entailed accepting the
division of labour entailed by the idea of brain-as-machine. With the
contrary hypothesis, an investigator would not know where to file their
results, so to speak. I am still not sure that this explains the
hypothesis.

The second question though is: why and how could those studying the
brain be so blind to well-known facts that made it obvious that the
brain was a changing, growing, self-healing, learning developing
organism just like the thinking human being whose functioning it underlay?

I credit Yrjo Engestrom for reminding us that what he calls a "system of
activity" or what I call a project entails not only a common object, but
also norms and rules, norms of belief, semantic norms and practical
norms. Being part of a project evidently makes one utterly immune to any
proposition calling the raison d'etre and modus operandi ('csure the
Latin) of your project, just as it rules out behaving "inappropriately"
or using words in ways that do not fit into the semantic norms of the
project.

It is just that it can be quite startling how strong these taboos are:
witness the holocaust, mass death through asbestos,  all the wars of
history, ...
