The evolutionary conceptual model outlined in this chapter will be advanced as an extension of our Simmel abstract general model in Chapter 1. In the main model, the time dimension, space, numbers, the polarity of order and change are all present, but the overall direction of the model is to merge into an infinity of potential forms of sociation. In the second model, the first will be assumed and the purpose then is to convey the dynamics of forms in the context of evolutionary change based on the principles of 'selection", involving a movement from lower to higher levels of social organisation, but allowing for regression as well as progression. The underlying philosophy in both models — and for Darwin and Simmel — is relational monism and materialism.
