Why do Anything

This paper develops a minimal structural answer to the question “Why do anything?” in a world understood as fluid, relational, and continuously evolving. Instead of grounding action in psychology, morality, or preference, the paper identifies five operators—coherence, non‑collapse, repair, shared world maintenance, and generativity—as the basic conditions that allow any system to persist across time.The argument is simple: in a reality without static things or isolated selves, action is the ongoing work required to maintain and extend coherence. Systems act to avoid collapse, to repair what breaks, to sustain the worlds they inhabit with others, and to generate new coherence that expands possibility. These operators are not ideals but structural necessities for continued existence.The result is a unified, domain‑neutral account of action that applies across biological, cognitive, social, and ethical contexts. The paper offers a clear framework for understanding why systems move, adapt, and care for the worlds they share—and why coherent, non‑collapsing, generative action naturally produces environments where life can flourish.
