"I’m basically interested in intervention. The key question for me is: how can you intervene more systemically? Systems approaches make the assumption that things are interconnected. That’s the fundamental starting point. However, we don’t have the privilege of a God’s eye view of that interconnectedness, so there are inevitable limits to understanding, and it is those limits that we call boundaries. So systemic intervention, for me, at a fundamental level, is how to explore those boundaries, and how to take account of the inevitable lack of comprehensiveness and begin to deal with that."
