In the context of your phrase, "…and theory is not an ars fabricandi or method…," it seems to be arguing that theory alone isn't enough to create something. You need more than just theoretical knowledge; you need the practical skills and methods that make up the "art of making."
Here's a breakdown:
* Theory: Abstract concepts, principles, or explanations.
* Ars fabricandi: The actual practice, skills, and techniques used to create something.
* Method: A specific set of steps or procedures used to achieve a particular outcome.
The phrase implies that a theory might provide the foundation for a project, but it won't be enough to actually bring it into existence. You need to apply the "ars fabricandi" and use specific methods to translate the theoretical idea into a tangible reality.
