Aristotle’s Metaphysics: Core Concepts & Ethical Framework
Aristotle’s Metaphysics: Fundamental Divisions
Aristotle’s Metaphysics is fundamentally structured around three key divisions: the transcendental order, the categorical order, and theology.
The Transcendental Order
The transcendental order describes the universal predicates that different beings possess:
- First Substance: These are the individual, independent things.
- Unity: A being ceases to be itself if divided or added to.
- Essence: That which cannot fail to be what it is. The first substance possesses

Plato’s Simile of the Line: Levels of Knowledge
This section explains Plato’s Simile of the Line, outlining the steps the soul must follow to attain true knowledge. This is divided into doxa (opinion) and episteme (knowledge), each further subdivided into two levels:

Methodical Doubt and the Cogito
Methodical doubt is applied to all knowledge, as all true knowledge must be differentiated from sleep. That which cannot be doubted is the fact that we think and the ability to do so.
