Storge – affection
Storge (storgē, Greek: στοργή) is fondness through familiarity (a brotherly love), 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.
Philia – friendship
Philia (philía, Greek: φιλία) is the love between friends. Friendship is the strong bond existing between people who share common interest or activity. Lewis immediately differentiates Friendship Love from the other Loves. He describes friendship as, “the least biological, organic, instinctive, gregarious and necessary…the least natural of loves” – our species does not need friendship in order to reproduce – but to the classical and medieval worlds the more profound precisely because it is freely chosen.
Eros – romance
Eros (erōs, Greek: ἔρως) for Lewis was love in the sense of ‘being in love’ or ‘loving’ someone, as opposed to the raw sexuality of what he called Venus: the illustration Lewis uses was the distinction between ‘wanting a woman’ and wanting one particular woman – something that matched his (classical) view of man as a rational animal, a composite both of reasoning angel and instinctual alley-cat.
Agape – unconditional love
Charity (agápē, Greek: ἀγάπη) is the love that brings forth caring regardless of the 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 – as Lewis puts it, “The natural loves are not self-sufficient” to the love of God, who is full of charitable love, to prevent what he termed their ‘demonic’ self-aggrandisement.
