Just started reading Manuel DeLanda's 'A New Philosophy of Society: Assemblage Theory and Social Complexity'161 - a brave title! But it's got me braincells going on a Monday, so it can't be all bad. He's immediately argued against reductionism at the micro and macro levels and started talking about things being 'more than the sum of their parts'. He proposes to take the reader on a journey through all the nested levels existing between micro and macro -

It is my hope that once the complexity of that forgotten territory between the micro and the macro is grasped at the visceral level, the intellectual habit to privilege one or the other extreme will become easier to break.

Digs are had at structuralists (macro-reductionists) and economists / social scientists who build theory on the individual, and aggregates thereof (micro-reductionists.) Oh, and Anthony Giddens (a 'meso-reductionist', apparently!)

Here's some Monday musings its caused, using Icosystem's Game and the genes of ants to bounce off.
