Classification

Froeb (Thinking-book) / traditional logic

The first dimension of systematic thinking --- ordering things by type, kind, category. Classification answers the question "What is this?" or "What kind does this belong to?". It corresponds to the judgments of quality and quantity: "This is an X" (quality) and "This has Y many features" (quantity).

Grenzen

Mere classification remains external --- it does not say **why** something is classified this way or **how** the classes are related. For this, the second (articulation) and third (relation) dimensions are needed.

- Biological taxonomy (kingdom, phylum, class, order...) - Library catalogs (organized by topic) - Diagnostics (which type of disease is present?)

Systematischer ort

Classification logically corresponds to the immediate judgments (Ch. 10.6-10.7) --- the first steps of the explication of the concept. It is the simplest, but indispensable, form of order.
