Zhuangzi
Things being equal
Whose ruler is this
Zhuangzi, Discussion on Making All Things Equal
Two people argue to the end and neither is convinced. Why Zhuangzi says a third person won't settle it either.
What actually happened?
Zhuangzi asks an almost mischievous question. A person sleeping somewhere damp gets a bad back — does a loach? A person up a tree is frightened — is a monkey? Of the three, who knows the proper place to live? He extends the logic to argument: if you beat me in a debate, are you actually right? Bring a third person to judge, and whether they agree with you or with me they have already taken a side. How could they settle it? This isn't abolishing right and wrong. It's a reminder that right and wrong always speak from inside some standard.
Before arguing, ask whose ruler is being used
There is a right and wrong on that side too, and one on this side. Most deadlocks aren't disputes about facts, they're disputes about standards — each conclusion holds inside its own. Until the standards are on the table, no amount of discussion converges.
Engineering says the design is good because it's maintainable; the business says it's bad because it ships late. Both are right. They're scoring different functions.
The third party brings a standard too
Calling in a more senior person looks neutral and is really introducing a third standard. It ends the argument by authority rather than by understanding, so the same disagreement reappears unchanged the next time.
The boss rules and both teams comply. Three months later the identical fight happens on a different project.
Move position and the ruler changes
Zhuangzi's method isn't finding the one correct ruler. It's acknowledging where your own came from. Do that and the other conclusion stops being 'wrong' and becomes 'true under his conditions' — and then you can discuss conditions instead of correctness.
Swap 'your plan won't work' for 'given we're prioritising the ship date, what does your plan cost?' Same subject, different conversation.
How do I use it today?
Where you are: a disagreement keeps recurring and never resolves.
Ask first: what is each side optimising? Can both targets hold at once?
Where it goes wrong: ending it by authority without touching the difference in standards; treating the other conclusion as an error rather than as correct under other conditions.
Lines to keep
There is a right and wrong on that side, and one on this side.
If you beat me in the argument, are you actually right?
