The technical definitions given by engineering "standards" organizations are often instrumentally useful, and bear some relationship to the phenomena they are intended to describe.

But you have to understand that these are metaphoric uses of the words in question. A standards organization is not an authority on semantics. The subjective aspects in our judgments about "brightness" can be argued to be essential to the semantics of the term.

Sorry, not getting your point. The statement I responded to began with, "CIE states that brightness..."

In the context of the CIE it has a clear meaning describing one of the subjective aspects of color.

Clearly the word has been abused and misused here on DPR, where it has become a synonym for lightness, luminance, illuminance, ISO, etc. etc., despite a very long history of use in photography and color reproduction that agrees with the CIE definition.

Sorry to be so obscure.  As a graduate student, I studied with a philosopher named Sydney Shoemaker, a noted "ordinary language philosopher" who uses "conceptual analysis" (derives from Wittgenstein's later work) as a way to understand the semantics of ordinary language terms both in their ordinary and scientific uses.  In ordinary language philosophy, the commonsense meanings are argued to be primal.  So-called "technical definitions" are held as suspect.

The short of it: A term like "brightness" is an ordinary language term, and refers to whatever our ordinary uses of the term refer to.  If we need a scientifically respectable account of a literal meaning, we have to begin here, and preserve the referent.

In instances where an ordinary language term has been employed as a technical term, one often finds that the term has been divorced from its referent, and thereby from its meaning.
