Aristotle's Ten Categories

CORE DEFINITION
Aristotle's Ten Categories, set out in his Categories, names ten basic kinds of predication: substance, quantity, quality, relation, place, time, position, state, action, and affection. Its core proposition is that anything that exists can be described through these dimensions, so the list works as an ontological checklist against omission. The key qualifier is that the categories are dimensions of description rather than rigid boxes, and Aristotle himself treated substance as primary while the others depend on it.
SCAFFOLDING EFFECT
Reduce cognitive load
- Description sweep: walk through all ten categories in order to describe a thing completely. - Omission check: notice which of the ten dimensions your account has left entirely blank. - Relation focus: examine relation, place, and time rather than stopping at the bare substance.
Anchor fast decisions
Descriptions default to whatever the describer notices, so whole dimensions go unexamined and disputes arise from parties answering different questions. Forcing a pass through fixed dimensions makes the omissions visible and separates questions that were being conflated, which is why the list functions as a diagnostic rather than a taxonomy.
