The Single Rule

A contractor takes your deposit and never returns. A landlord clears out your closet while you are at work. A partner cooks the books to win an investor who would have walked away from honest numbers. A town condemns a family's home and calls a fraction of its worth "just compensation." Four wrongs that share no surface feature. Now try to write the one rule that forbids all four at once. "Do not steal" misses the broken promise. "Do not lie" misses the seizure. Every easy answer runs too narrow or dissolves into a sentiment you cannot test.

This lesson states the rule that holds. One sentence, every word of it earned, precise enough to weigh any action, any contract, any policy, or any law against a single standard. You will run cases through it yourself and watch them resolve.

What you gain is not another opinion to argue. It is an instrument. Hold it, and your verdict no longer bends to your mood, your party, or the authority of whoever wrote the rule you are judging. The rule itself waits inside the course.
