Professional work is typically viewed as based on ‘expert’, that is, logical knowledge and systems thinking. I show in this blog that such a view is mistaken since it encourages doing professional work within the confines of closed systems geared to efficiency and control. In the blog, I see such systems as self-serving and ideological in that they stand against an ‘open systems’, social-ontology view of human agency as a causal power bringing about societal change. Architectural practice is used as an example. Following Prof. Freek Persyn’s inaugural lecture at the ETH, Zurich, I demonstrate what it looks like to view architectural work as an expression of human agency in the sense of Bhaskar’s and Archer’s social ontology, thereby consciously placing it within the Social Cube. What in this blog is said about architectural practice can easily be extended to any professional practice one is involved or interested in.
