:::??? In what way is saying "its useful" an NPOV issue?? If someone uses this for something, then its useful.  In my case, I am reading an article on Markov logic networks, wherein linguistic reification is one of the early steps, followed by conversion to a lambda calculus form, and then many other steps. In this calculation, reification is a crucial step.  The "natural stupidity" article cited probably just says that using reified forms (aka QLF's or quasi-logical forms) in certain ways is stupid; it cannot claim that QLF's in and of themsels are useless.
