Activity Analysis Network #13: Learn, Weave, and Agency Frontier

These articles collectively mark a significant expansion of the World of Life framework, introduce Spatial Heuristics as a new methodological stream, and advance ACS to version 1.2 with a refined model of the actor.

The Landscape of ACS 1.2 and a New Model of the Actor

The ACS model is oriented differently. It is not primarily about constraint or calculation. It is about orientation — what directions are available, what positions are possible, what forms of action are open.

Appropriating Activity Theory #13: Agency Frontier Behind the Hierarchy of Human Activity (2020)

When I sat down to write this issue's column, I found myself asking a question I hadn't asked before: Does the tradition of Activity Theory have anything analogous to the four boundaries of the World of Life?

World of Life: Four Positive Frontiers of Project Engagement

I rediscovered a diagram I made in 2022 — The Shaman's Mandala — which maps four concepts from the Ecological Practice Approach onto a four-boundary structure: Affordance, Supportance, Attachance, and Curativity, each occupying a distinct position.

Spatial Heuristics: From the Margins to the Center

The present case study documents six weeks of systematic development in which a single structural discovery — the Double Square diagram — served as the engine of an entire theoretical expansion.

Spatial Heuristics: Developing a Pedagogy for Cognitive Hydrology

If Lake 42 documents the Generative Confluence pattern — the development of Creative Life Theory v3.0–v3.1 through the convergence of multiple streams — then the development of ACS from v1.0 to v1.1, across January and February 2026, documents a different pattern: Spatial Heuristics.

World of Life: Four Negative Frontiers of Knowledge Engagement

Beyond those edges, a second square frames the four negative frontiers: Mystification, Dogmatism, Echo Chamber, and Tragedy of the Commons. They are not distant dangers. They occupy the zone just outside the working space, adjacent to every boundary, always within drift.

The L3D Model (v1.0, 2026)

A Knowledge Framework for Supportive Life Discovery

Learning Landscape: Revisiting from the World of Life Perspective

The 2015 framework was not wrong — it was, in retrospect, theoretically necessary. The practice had anticipated the theory. The four perspectives were already there, already corresponding to four boundaries,...

The Significant Themes Framework (2026)

Based on observation and personal experience, I identified eight recurring themes, which correspond to eight turning periods, dividing into the regular group and the special group.
