Eros (Romance) - This is love in the sense of 'being in love'. (This is distinct from sexuality.) This kind of love longs for the emotional connection with the other person. According to C.S. Lewis, sexuality is called "Venus." It can be part of "Eros," but on its own, it is not one of the loves, just desire (not to be confused with Lust which is this desire expressed in a sinful way ).
Agape (Unconditional Love) - This is the love that brings forth caring regardless of circumstance. The essence of agape love is self-sacrifice. It is also a decision, not fueled by pure emotions (theoretically).
Crusty Caretaker: Children can love him even though he does nothing because he's familiar
Dysfunction Junction: What could be more natural than children to feel no love for an unloveable parent?
Et Tu, Brute?/I Have No Son: Affection is so naturally jealous that any deviation from the ethos of home, whether falling below it or rising above it, often feels like a betrayal to the rest of the family.
Feminine Women Can Cook: "Mrs. Fidget" (an example of self-serving generosity) always cooked for her family; even when they were happy with a cold meal.
Nature Lover: Analyzed in the course of dealing with the subhuman before the human.
Patriotic Fervor: Analyzed along with nature love as one of the most notable loves of the subhuman. Lewis describes five forms, in descending order from the very good to the very bad to a form sunk so low that it isn't even a love anymore.
Pet the Dog: Love for anthropomorphized beings such as pets and dolls is treated under affection rather then love of the subhuman.
