Humans are often portrayed as rational beings who prioritize clarity and perfection. In this lecture, however, I offer a different perspective that centers on the idea of humans as unfinished drafts. From this view, a person is a playful, evolving creature. If that is the case, then an essential part of the world for us is the so-called play space, a space for development and growth. This raises further questions: What is the role of play space in the city? Is it even possible within urban environments?
