Yet Another EXample of reification:
Reification (also known as hypostatisation or concretism) is a fallacy of ambiguity, when an abstraction (abstract belief or hypothetical construct) is treated as if it were a concrete, real event or physical entity. In other words, it is the error of treating as a "real thing" something which is not a real thing, but merely an idea. For example: when one person "holds another's affection", affection is being reified.
OR another example - what relativists do.
But this is not only an idea, this is also a real stupidity.
