Let us ask if love/hate/indifference is real then how it came about.
What is love derived from? Hate? Indifference?
What is hate derived from? Love? Indifference?
What is indifference derived from? Hate? Love?
Do they just appear from nowhere? Do we just choose?
Indifference is more natural and common than either love or hate. Indifference then would be the default state.
It is understood that love can grow into hate.
So humans do not care, then it grows into caring or love. Then caring or love can grow into hate.
Also love or hate can grow into indifference.
[We cannot credibly sustain the notion that God is love if we are made indifferent.
It is just a contradiction.
Even if it were not, why would a God who wants us to love make it so hard for us to do so? Why give us indifference as our natural state? The argument that free will is a gift from God and gives room for growth is popular. But this amounts to saying that God can set a plant where there is hardly any water and blame it if it does not grow.
If we are made indifferent, then God must put the love in us so it is not ours. That is not free will.
We will let you ask yourself if this concept of a loving God is, "I will use faith to construct a narrative. I will rise above that unfeeling God who does not love, by having a false version of him that does love."]
How does love relate to reason?
Reason is a tool that gives humans a dignity that non-humans do not have. It helps us avoid error by thinking correctly and in tune with reality. That matters deeply for reality is not about humans or anything. It does not care what anybody thinks. We need to think correctly to avoid dangers. So, reason and love go together in principle but in practice reason cannot tell you it is wrong to look after yourself and your family and ignore the pain outside your front door. Reason works through exposing contradictions, but there is no contradiction in that one. And there is no contradiction in the view that for some reason only you and perhaps your loved ones exist while everybody else is just an illusion. The paradox is that love is needed by reason while reason and love attack each other.
Reason cannot prove that anybody else exists apart from you and maybe your family. So it is not helpful if you are going to love somebody other than yourself. There is no logical absurdity in thinking you alone are real and living in some dream.
That again highlights that love is vague.
Clear definition or not, in practical terms, love is hard to apply. This is another deep problem. It is a huge and destructive one. Take Mormons. For them loving yourself meant being glad to have your blood spilled to atone for your sins. In that faith, some sins cannot be forgiven and you have to die to be able to pay the penalty and move on. Loving your neighbour to death meant that you could call on fellow Mormons to stab or shoot you so that the blood would flow and your unpardonable sin would be dealt with.
It is possible to give love, to help and feel warm about a person, for its own sake and not theirs. You treat the other as a project not a person. You want the feelings you have for them purely for your enjoyment. This is not love. It is self-indulgence. It looks good to others so it is virtue-signalling. It even looks good to yourself. You are virtue-signalling to yourself as well. You will celebrate this person and how you feel about them no matter what they do or don't do. They are there for what you want them for. So it does not matter if they do grave harm to themselves. You feel unconditional love. This love is really a euphemism for celebrating the other person even if they set on the road to self-destruction.
You can do all that to yourself too. You celebrate yourself no matter what. You want others to celebrate you.
So that is unconditional love. If you affirm and celebrate such "love" you are only contributing to a culture of lies and harm.
The best view is that ideas about love are more about people wanting to feel so special that their friends do not mind what harm they do. People cannot really want unconditional love from everybody else. That is not realistic. But they do want it from those close to them. And themselves!
CONCLUSIONS: Real love would be hard to find. Much love is not real.
