Catholic theology must point out the so-called "negative" errors of ideas alien to Catholicism. I am speaking of "positive" and "negative" in psychological terms. There is no place for them in theological language. "Positivism" does not mean "hope." They are distinctly different. It is also misleading to be overly positive, as it is not objective nor realistic.
What an obtuse paragraph that says absolutely nothing. "Glass half full" is actually a term used to describe a certain type of person, a positive, upbeat individual who sees the best in everything.
"Glass half empty," OTOH, describes you.
