You got it completely wrong. *Not* being able to feel sentimentality is a hallmark of sociopathy, not the inverse. Take sentimentality away from the game and you're pretty much only left with the obvious financial incentive.
I don't think you know how to read.
Sentimentality is the result of personal attachment and fear, and is self-centered. Compassion is concern for the suffering of another with an inclination to provide support and comfort. For the un-educated or inexperienced - Sentimentality is often confused for compassion.
Hmm, I may well be “uneducated†in whatever specific theory it sounds as though you’re citing there, but it certainly seems to involve a substantive claim about sentimentality that’s not entirely supported by the use of the term in natural language, or else is simply defining sentimentality in a specific way that makes the claim trivially true. There
might be a useful conceptual framework there in light of which to consider the distinction between sentiment, nostalgia, compassion, etc but probably not while being quite so dismissive of others’ comprehension skills!
Not that you weren’t a little provoked by Seraphael saying you got it “completely wrongâ€, and I do agree that sentimentality is not the same as passion or just emotion, which sounds more like what they were thinking of.
