Cannon names homeostasis — the body’s active work to hold internal variables in livable ranges — and maps fight-or-flight as organized autonomic response to threat. Biology pushes back on the idea that stress is only a story you tell yourself.

Key principles

  • Homeostasis — Physiological variables are actively regulated — stability is work, not default.
  • Fight-or-flight — Sympathetic mobilization prepares action under threat — adaptive, not moral failure.
  • Visceral wisdom — The body coordinates organs and chemistry toward survival goals — often before conscious narrative.
  • Stress vs story — Interpretation matters — but autonomic state sets the menu of plausible moves.
  • Social extension — Cannon linked physiology to social stress — context is not separate from biology.
  • Historical science — Core ideas endure; some specifics were revised — read as foundation, not final word.

Core science

Foundational psychophysiology text — Cannon’s homeostasis language still structures stress education (Why Zebras Don’t Get Ulcers updates the HPA story). Pair with Somatic witnessing lineage when the room needs body-first vocabulary before cognitive fixes.

Application

Reach when shame attaches to activation — heat, gut, breath — as if the body betrayed character. Open Homard metaphor on the Atlas shelf for the lobster-moulting image of regulated change under load.
