Andy and David Well, I ask a question and here I go on another magical mystery tour. Andy asks a simple question if activity is more fundamental and is implicit in philosophical assumptions about discourse and communication. A nice little question around which we can have a civil discussion among friends:)) Then David adds a level of complexity by suggesting we should be looking and asking about part/whole relationships and I'm brought back to Merleau-Ponty's theme. David hints that we should read Jean Schmittau's work on researching Davydov's perspective on learning. This leads me to google scholar where I find an article Jean wrote in 2004 [see attachment for anyone interested in following this mystery tour bus]. I'm going to read this article to find out more about part/whole relationships. David, a question on this topic. You mentioned that Vygotsky shifted his focus from activity as material to focus more on the semiotic. Do you see connections between that topic and this current topic? I will have to read David's last response a few more times as it left me more puzzled than illuminated. However, it has opened up more reflection on activity, discourse & dialogue, and part/whole relations. There goes the simple question Andy started with. I will end with this comment from David, I guess what I would say about this is that it is not really about discourse or activity, but rather about play. Of course, both discourse and activity CAN be seen as play and indeed ARE seen as play by children. But the key component is not so much mediation as contradiction. David, you will have to say more on this but I do like to end with the notion of play.
