Every person carries a worldview — the sum of everything they understand about how the world works. Most of it is never organized. It lives scattered across notes, books, conversations, and memory, and it quietly degrades under load. The question here is a structural one: if you wanted to organize everything you could possibly learn, how would you actually do it?
There is no single true map
The instinct is to hunt for the one correct way to divide up all knowledge — the true first principles. That search never ends, because there isn’t one. A physicist, a librarian, and an investor would each carve knowledge differently, and each would be right for their purpose. So the goal isn’t a philosophically perfect taxonomy. It’s a structure built for what the library is actually for: filing things predictably, connecting them, and turning them into action.
Three kinds of things, not one tree
The mistake is assuming everything is one kind of thing that belongs in one folder tree. It isn’t. A worldview is built from three fundamentally different kinds of things — and telling them apart is what makes the whole thing hold together.
Axes — the index. Two coordinates apply to everything you could ever know: where it sits in space, and when it sits in time. Geography and Timeline aren’t topics competing for shelf space — they’re the grid every topic is plotted on. Treat them as axes rather than categories and half the confusion disappears.
Domains — the content. What a piece of knowledge is actually about. These stack by emergence, from the given world to the made one: Nature (cosmos, matter, life) gives rise to Human Nature (the mind, the individual), which gives rise to Society (the collective — economics, power, culture), which gives rise to Technology (everything humans build). Each layer rests on the one beneath it.
Lenses & methods — the skills. Some things aren’t subjects at all — they’re ways of operating on any subject. Project management, critical thinking, a method of study: these are lenses you apply across every domain. They don’t live in a folder; they cut across all of them.
The value is in the connections
A tree tells you where something lives. It doesn’t tell you how things relate — and relationships are where insight actually comes from. So the most valuable layer sits over the folders, not inside them: cross-pollination, the graph that links areas around a shared subject. The more domains that intersect on a single question, the more powerful the answer tends to be. This is the layer that turns a filing cabinet into a mind.
The Worldview sits at the top and divides into three kinds of thing. Two axes — Geography (space) and Timeline (time) — index every area rather than competing with it for shelf space.
Four domains hold what knowledge is about, stacked by emergence from the given world to the made one: Nature, then Human Nature, then Society, then Technology, each resting on the one before it.
Lenses and methods — project management, critical thinking, space mapping — are skills applied across every domain rather than subjects of their own. Beneath all of it sits cross-pollination and synthesis: the graph layer that links areas around a shared subject.
The structure: two axes index every area, four domains hold what it's about, lenses are the skills applied across all of it — and cross-pollination links them.
A living structure
Organized this way, a worldview isn’t a static archive. It’s a living structure — built not to store knowledge, but to keep turning it into action. That’s the whole point. Knowing more only matters if it changes what you do.
