jmullaney says:
“1) Is there such a thing as love, and if so, is it a universal? In other words, every act can be said to either be one of love or not one of love or neither. Is there a universal truth as to what acts fall into which category?”
I agree with The Ryan about establishing some common ground. Webster’s has several definitions of love, but I think the closest one that would apply here is “the benevolence and brotherhood(sic) that people should have for each other.”
I think then what would be a loving act would be one for the common good of people. Sometimes that means doing what is harmful to one or a few for the greater good of the majority (like the father who suffocated his son to stop his crying so that the group of people he was with would not be discovered by the Nazis). And probably not everyone would agree as to what constituted a loving act.
jmullaney goes on to say:
“2) Given that, is there any point in generally always attempting to do the loving thing in regards to your fellow humans, or is it better, ultimately, to not bother?”
There again, that would depend on the individual person, and that person’s pyschological make-up and history. I was raised by two people who, although atheists, believed in kindness to friends and strangers, and to animals and the environment, and I saw those people reaping benefits of laughter and companionship and loyalty. Someone who grew up in a different sort of environment might view love differently.
jmullaney again:
“So, as for a life with or without love being different, obviously one who has chosen not to love would be able to chose different actions and therefore life would obviously be different.”
I don’t know if one really can consciously choose NOT to love, although one CAN choose isolation and withdrawal to prevent that love from wounding her/him.
I think that certain kinds of love are essential for human survival. There is the oft quoted story of how babies in a French orphanage failed to thrive if they were not cuddled, and some of them actually died until some smart nurses figured that out.
There is also something called an attachment disorder that appears in children who have been abused and uprooted so often that they are unable to trust or love anyone. In severe cases, these children must be watched constantly so that they will not injure other neighborhood children or kill pets.
I don’t know if any of that information is helpful to you; sorry this got so long.
