Storge – affection
Affection (storge, στοργή) is fondness through familiarity, especially between family members or people who have otherwise found themselves together by chance. It is described as the most natural, emotive, and widely diffused of loves: natural in that it is present without coercion; emotive because it is the result of fondness due to familiarity; and most widely diffused because it pays the least attention to those characteristics deemed “valuable” or worthy of love and, as a result, is able to transcend most discriminating factors. Ironically, its strength is also what makes it vulnerable. Affection has the appearance of being “built-in” or “ready made”, says Lewis, and as a result people come to expect, even to demand, its presence—irrespective of their behavior and its natural consequences.
Phileo – friendship
Phileo is the love between friends. Friendship is the strong bond existing between people who share common interest or activity. Lewis explains that true friendships, like the friendship between David and Jonathan in the Bible is almost a lost art. Friendship is a love just like the love between two lovers.
Eros – romance
Eros (ἔρως) is love in the sense of ‘being in love’ or loving me. This is distinct from sexuality, which Lewis calls Venus, although he does spend time discussing sexual activity and its spiritual significance in both a pagan and a Christian sense. He identifies eros as indifferent. It is Venus that desires the sexual aspect of a relationship, while Eros longs for the emotional connection with the other person.
Agape – unconditional love
Charity (agapē, ἀγάπη) is the love that brings forth caring regardless of circumstance. Lewis recognizes this as the greatest of loves, and sees it as a specifically Christian virtue. The chapter on the subject focuses on the need of subordinating the natural loves to the love of God, who is full of charitable love.
Pragma - practical love
Pragma is a pragmatic, practical, mutually beneficial relationship. It may be somewhat unromantic. A person who leans toward this type of relationship may look for a partner at work or where the person is spending time. Sex is likely to be seen as a technical matter needed for producing children, if they are desired.
Mania - obsessive love
Mania is an obsessive or possessive love, jealous and extreme. A person in love this way is likely to do something crazy or silly, such as stalking. The movie Fatal Attraction was about this type.
