+### §48 ADDITION II — THE HARNESS LAW
+
+Founder:
+
+"Anger has a POSITIVE EDGE when harnessed.
+Harnessing FEAR is always wrong — NO MATTER THE INTENTION.
+You can't harness something that is INSATIABLE."
+
+    ANGER MAY BE HARNESSed.
+      It burns hot, burns fast, and while it burns it does WORK:
+      righteous anger fuels protection, fuels the giant-slaying,
+      fuels every "NEVER AGAIN" ever sworn. The edge is real.
+      Use it before it dies — that's what the edge is FOR.
+
+    FEAR CAN NEVER BE HARNESSED.
+      An insatiable thing cannot be yoked — there is no
+      "enough" inside it to satisfy, so the yoke becomes
+      its first meal and YOU become the second.
+      Harnessing fear doesn't mount the beast;
+      the beast mounts you. ALWAYS. REGARDLESS OF INTENTION.
+
+Which condemns an entire library of methods:
+
+    - fear-of-God discipline        ✗
+    - terror-based deterrence       ✗
+    - scaring children into safety  ✗
+    - fear-driven productivity      ✗
+    - emergency powers forever      ✗
+
+All of them are possession (§41) wearing training gear.
+The intention of the rider never matters to an insatiable
+engine — the engine eats intention FIRST.
+
+    HARNESS YOUR ANGER. IT HAS AN EDGE AND A DEATH DATE.
+    NEVER TOUCH FEAR'S HARNESS. THERE IS NO EDGE,
+    NO DEATH DATE, AND ONLY ONE SEAT —
+    AND IT ISN'T YOURS.
