Now we've covered the relationships with postmodernity in the previous post, (I promise not to bring it up again, but I have recently been accused quite often to be 'almost postmodern', which -being an engineer myself- I find rather absurd) it is time to turn our attention to an Enlightenment favourite, namely rationality.

Methodological Stuff:

In my previous post, I defended a 'post-modern' stance in science, as I consider quest for singular concepts to explain all kinds of things to be somewhat outdated. Or, to be more precise, it is rather stupid to consider oneself a 'complexity thinker' and then believe that singular concepts can explain everything. This tie between post-modernism and complexity has been elucidated in a much better way than I can, by philosopher of complexity Paul Cilliers in his ground-breaking book, so I will not delve into this issue further.

The Pattern of Contextual Diminution

This pattern is a bit more involved,as it combines a number of other patterns. It also adds to theself-referential nature of PAC, as it describes the dynamics of anepistemological system, such as PAC.


  1. Introduction

  2. Patterns

  3. Patterns, Objectivity and Truth

Complexity and Randomness

This pattern is from System's thinker Gerald Weinberg, and has been extremely helpful to illustrate the difference between complexity and randomness. It is also a nice example of the self-referential methodology of PAC, as the pattern is used to discuss scientific approaches: science discovers patterns, which are then used to elucidate scientific processes!
