I am not aware of such a radical position. But there several projects 
with a strong social approach (which could be socio-psychology, 
socio-linguistic, social interaction -- although there are relations, 
there are also important differences). I would suggest works from Cobb, 
Brousseau, Ball, Herbst, Bartolini-Bussi and Boero, and others, I have 
not mase a systematic search. I send you an old paper of mine (different 
mail), just to give you an idea of the way I understand this issue.
