The Five Domains
All of human inquiry, divided into five great branches — each bound to one of Plato's solids. Enter one to see its fields, and every topic refracted through the six modes of knowing.
Formal Sciences
tetrahedron · 4 fields · 27 notesThe bedrock layer — abstract structure, formal system, and necessary inference. Mathematics, logic, computation, and systems theory: the languages in which every other domain is written.
Natural Sciences
cube · 4 fields · 12 notesReality measured. Matter, energy, life, and the laws they obey — knowledge sampled from an inexhaustible world and compressed into law.
Applied Sciences
icosahedron · 5 fields · 4 notesKnowledge turned into capability. Scientific law bent toward design — circuits, processors, machines, and materials built to a purpose, under constraint.
Social Sciences
octahedron · 7 fields · 7 notesThe human collective as a system. Value, mind, language, law, and power — the emergent order of people acting together, and the forces that bind and divide them.
Humanities
dodecahedron · 5 fields · 13 notesThe pursuit of meaning. Existence, beauty, memory, and myth — the questions that remain after everything measurable has been measured.
