The whole idea of action being a carrier of information is something that comes directly from theater. That's, in some ways, the one thing I've been trying to contribute. I still write things outside of architecture - not really fiction, but not nonfiction. I like dialogue as a form, because the text is only the trace of an action. The consequential information is carried in the action you choose to put on that text.

In architecture, to do anything beyond object form is often treated as something extra-disciplinary - something outside the discipline that has nothing to do with art. So I'm making it clear that this is an artistic choice. It's not everyone's artistic choice. Some people should choose only to make object form because that's what gives them pleasure. But there are people for whom aesthetic pleasure comes from doing something else, and why would you deny that choice? It's another autonomous choice.

If you're steering a boat down a river, it's not something about which you can know that. You can only know how to do it. It's unfinished, it has no start-stop time, it's fluid. Practicality relies on indeterminate markers. It's just another kind of knowledge that's sexy, in a certain way. It's reactive, and often physical.

I love making object form; I wish I was doing more of it. I admire the research of my colleagues, and sometimes it makes me sad when their beautiful work - the deep dives into formal research and nuances of geometry and so on - ends up circling in more and more circumscribed contexts. I wish they were more powerful. It's not a modern proposition. Active form doesn't kill object form. I want my students to have all those skills related to geometry, shape, measure, scale, etc., plus skills for using space to manipulate power in the world.

Architects and urbanists are fascinated with cities that are shrinking, like the Rust Belt cities. Or, alternatively, we are fascinated with the growth of favelas and informal settlements. The 2008 financial crisis made these changes more extreme. The subtraction protocols rehearse a way of thinking about multiple properties in counterbalancing interdependence - not just the shaping of one property but the ratcheting interplay between properties.

Few would look at a concrete highway system or an electrical grid and perceive agency in their static arrangement, spaces and urban arrangements are usually treated as collections of objects or volumes, not as actors. Yet the organization itself is active. It is doing something.

Rather than asking architecture to be more interdisciplinary - a perennial issue within the discipline - I am suggesting that other disciplines might exploit the powers of architecture and urbanism. When addressing urgent situations, whether it's the depletion of the rainforest or abuse of labor, well-meaning people are working with tools, like standards, that seem like very blunt instruments. I am suggesting that spatial variables that are underexploited in governance might add to that repertoire.
