Your Definition
The principle that entities (concepts, arguments, people) are defined not by fixed properties but by their position on multiple intersecting spectra. Your identity isn't "logical person" or "illogical person"; it's a point in spectral space defined by your position on spectra of rigor, intuition, evidence-use, emotional reasoning, and countless others. The law of spectral identity means that no one is simply anything—we're all complex coordinates in multidimensional logical space. This explains why you can be brilliant in some contexts and hopeless in others, why someone can be a genius in their field and an idiot in daily life, and why "knowing someone" means understanding their spectral coordinates, not just slapping a label on them.
