I'm looking for a term to express that a certain component of a system gives coherence to it. I've found that coherencer exists, but it's used in just a couple of physics papers, and it's sort of a neologism. Consider the next example:
Edit 1: The principle of justice as fairness was the "coherencer" of Rawls' system.
Edit 2: I came across the term coherer, which is an electrical device that brings coherence in a system. Would this be a valid term outside the electrical arena?
Would anyone suggest alternatives please? thanks!
