"Love because love" - so many people say that. What nonsense? Isn't it loved for something valuable in this person?
They love, just because they love .. The important thing is whether they can .. This is more important. After all, love is a gift from God, the ability to give, not take .. As I understand and think so.
Only children, perhaps, take when they love. BUT for little angels and it's not a pity, really ... :)))))))))))))))))))))
Conscious love has clear concrete - basis and virtues.
Subconscious love has implicit - the basis and the merits - but science can explicitly and specifically indicate them.

Conclusion - "for what they love" - it can be explicit or implicit.
Do you love your mom FOR SOMETHING? Or children?
Love for a partner - yes, pragmatic.
But this is all different love.
You can't generalize like that.
Love is multifaceted
Do you love or in search of love?
