I think perhaps "Love" is different from "Caritas"

But "Love" in its general sense is more related to "Connection". "Caritas" transcends connection and is more related to "Willing the Good".

In today's topic I will only talk about "Love" not "Caritas"

I agreed. Love can be selfish sometimes.

回复 @圆环之理：I think Caritas is a kind of sefless love. It refers to "love all human", not a specific person.
