I do not know why this quote bothers me:
Great minds discuss ideas
Average minds discuss events
Small minds discuss people
Seems too pretentious, presumptive, and superficial to me ...
More thinking revealed part of the problem, which is basically mis-use of language. "Ideas", "Events", "People" are very different "things" and applying the verb "discuss" hides this aspects. We "love/hate" people, "learn from/experience" events, and "evaluate/examine" ideas. The same act of "discussing" has different dimension when applied to each of the three.
I dislike the quote because my life is consistent with it, in the sense that I have kept busy most dealing with ideas, then events, then people ... Feels like an imbalance
