Abstract

The present issue of Mind and Matter on the concept of 'pragmatic information' has originated from a frutiful collaboration with Peter beim Graben,whose active involvement as a co-editor was decisive for its pro- duction and is greatly appreciated. The following extended editorial intro- duces the topic within a broader background. In particular,the concept of pragmatic information will be related to the study of complex systems and to concepts of complexity that are not in detail addressed in the in- dividual contributions to the issue.Finally,possible connections to an epistemically understood distinction of mental and material domains of discourse will be indicated
