Metaphysics
Fourteen books collect investigations of first causes, being as being, substance and actuality. They preserve several routes of inquiry, unresolved difficulties and vocabularies that cannot be reduced to one formula.
Understanding the text
The transmitted title and order do not describe a continuous book written in one sitting; their formation belongs to editorial history.
Key points
- 01
Being
The multiple senses of being are related to substance, seeking unity without erasing their differences.
- 02
Potentiality and actuality
A real capacity differs from abstract possibility; actuality receives explanatory and ontological priority.
- 03
First mover
Book Lambda examines an unmoving substance and thought thinking itself, whose connection with other books remains disputed.

Learning how to ask “why”
A first journey through Metaphysics via the desire to understand, types of explanation and the distinction between potentiality and actuality. An invitation to slow down over its terms.
From experience to first principles
Book Alpha connects knowledge with experience, skills and the search for reasons. Experience recognises cases; a more general inquiry asks why things happen this way. This progression does not make experience useless. It shows how repeated observation can become a question about what explains something and about the limits of that explanation.
Do not give “why” just one form
Investigating causes does not merely identify an earlier event that triggers a result. Matter, form, the source of change and an end are distinct routes to understanding. Use a manufactured object to grasp the distinctions, then ask whether their application remains convincing in nature. A useful classification does not by itself establish its universality.
Distinguish potentiality and actuality
A capacity is not identical to its exercise: knowing how to play an instrument differs from playing it now. Potentiality and actuality help explain change without saying that something comes from absolute nothingness. The distinction has more complex metaphysical uses. Begin with examples, then examine what the reasoning adds to simply observing a transformation.
Questions to carry into your reading
- In an explanation you find convincing, what kind of “why” receives an answer?
- What distinguishes possessing a capacity from exercising it well?
Understanding sometimes requires several complementary explanations and precise attention to the words connecting them.
How to read it
Begin with Alpha, Gamma and Theta before the demanding treatment of substance in Zeta and Eta.
