Let me come back to our attempt to do a little bit of the sociological theory which might be helpful in watching what happens to modern society when first the computer, then the internet, and now web 2.0 are introduced to it. The idea is to describe a change from modern society, based on the dissemination medium of the printing press, to the next society, based on the computer, the net, and the grid. We call what is emerging "the next society" to honour Peter F. Drucker who gave it not only that name but also looked in the consequences of it for management and organization (see his book "Managing in the Next Society", New York 2003). "Next" is a perfect name, since it spells out what the next society is about: to always be able to find a next step while watching, from the corners of your eyes, what is happening next to it. That is why we think that George Spencer-Brown's notion of form is perfectly suitable to give that way of operation, iteration, and reproduction its core notion.

We start with some ideas about network synthesis.

Sociological theory has always been a theory of the network synthesis of social action. In the computer age of the society this has to become explicit. To know about the form of the network synthesis of social action means to know how our society, the next one, the knowledge society deals with its dynamics by generating specific structures able to sustain social action.

I will here present two attempts to take a closer look at the network synthesis of social action. It first will go back to Niklas Luhmann's conjecture about the structures of the society depending mainly on culture forms able to deal with the surplus meaning, or overflow, produced by the introduction of new media of the dissemination of communication. This is a conjecture about the structures of the society being the outcome of the society having to find a solution to new kinds of overflows by switching from one culture form, and the structure, order, and understanding of the society coming with it, to another one. The morphogenesis of the society depends on these dissemination media eclipsing one another, all of them staying present, however, even if changed in scope, scale, and range.

I will then try to develop a model of social action which takes into account the culture form possibly able to deal with the surplus meaning brought about by the introduction of the computer as a medium of the dissemination of communication. This model is a form model, integrating ideas from sociological systems theory and sociological network theory. It tries to be simple enough to be able to catch the complexity of social action.

We begin with presenting some general ideas on a sociological theory of social action. And we conclude with a proposal to go from objects and subjects of social action to what we will call the catjects of social action. This actually is a proposal to look at categories which are able to describe and explain what kind of underlying reality is produced and reproduced by the *eigen*-values of social action. These catjects combine reference with self-reference, and with some way to account for the unknowable, in unfolding, exploring, and synthesizing a network of variables whose values social action brings about, calls on, and subverts.
