Human Scale
What one person can understand, maintain, and be responsible for. The threshold beyond which systems stop serving people and start requiring people to serve them.
The Principle
Scale changes the nature of things. A village council and a national government aren’t the same thing at different sizes — they’re fundamentally different creatures. A tool you can repair is different in kind from a tool that requires a specialist.
Schumacher made this economic. Illich made it institutional. Le Guin made it fictional. Alexander made it architectural. The insight is the same: past a certain scale, systems develop their own logic that overrides human intention.
The Test
Can you explain how it works? Can you fix it when it breaks? Can you choose not to use it? If the answer to any of these is no, you’ve crossed the threshold.
This doesn’t mean everything must be small. It means the interface between the system and the person must remain comprehensible. A complex greenhouse climate system is fine if the grower understands the principles. A simple app is not fine if the user has no idea what it does with their data.

The question isn’t “how big can we make it?” It’s “how big can it get before it stops being ours?”
