INTRODUCTION

English translation pending.

CORE DEFINITION

A foundational distinction in metaphysics, debated since Plato and Aristotle. Universals are properties or kinds shared by many individuals, while particulars are the concrete, unique entities that have them. The core proposition is that statements about kinds and statements about individuals are different claims, so the level must be specified before reasoning proceeds. The key qualification is the unresolved debate over whether universals exist independently or only in language and mind.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Level check: ask whether a claim is about a class of things or about one specific thing. - Instance test: look for a particular that contradicts the general statement. - Abstraction audit: check whether the abstraction has erased differences that matter.

Anchor fast decisions

General statements compress many individuals into a single property, which makes them useful for prediction and useless for exceptions. Every such statement is true of the class while individual members may deviate from it. Keeping the two levels distinct prevents the common error of applying a class-level claim to a particular and being surprised when the particular does not conform.
