"Where" should be the first issue for any activity. In 2017, I wrote a ppt named "Activity as Container" in which I used the metaphor of Container to understand Activity Theory and other Practice Theories.

Later, I developed the Ecological Practice approach in 2019 and developed a further idea for Container: Containance.

The metaphor of Container was adopted from George Lakoff and Mark Johnson’s conceptual metaphor Container and image schema Containment. However, I went beyond their original ideas. I coined a new term Containance which refers to dialectical boundary of Container and my other ideas about “Containee — Container” in general.

Last year, I applied the Container Thinking to discuss platform. You can find more details here:

Platform, Platform-ba, and Platform Ecology
