Re: [xmca] Dialects of Development- Sameroff



Yes, I was thinking that Lewontin's triple helix might be seen as the "biological evolution" leg in yours, Martin. I like yours. And as you point out, it is on an entirely different level of motion and development than Lewontin's on biology. Yours strikes me as being about human development, reflecting Vygotsky's conceptualization of the interweaving of the processes of phylogenesis, history and ontogenesis.

If we keep up this idea of putting helixes within helixes - and we already do have a leg up on triangles within triangles, don't we? :-)) - we could wind up with the complex braiding that Mike describes in Cultural Psychology.

That's right, Steve, though I'm pretty sure I didn't see this title until after I made the diagram. And of course Lewontin is referring to different factors. And, also, of course, collagen actually does have a triple-helix structure, which Francis Crick thought was more interesting than the double helix of DNA, but which got very little attention.

On the triple helix metaphor: Richard Lewontin used it in the title of his 1998/2000 collection of essays _The Triple Helix: Gene, Organism and Environment_. His core theme regarding biological development is that solely considering the interaction between gene and organism makes for bad biology. The environment has decisive influence as well.

What do others think of the double helix (and/or the other visual images in the article). How central is the double helix (either as an "is Like" or "IS" objectification) to your notions of the human sciences?
