To conclude “Self-Improvement Week”, I turn to C.S. Lewis and a summary of his book The Four Loves. Originally intended to be a discourse on the John’s statement that “God is Love”, it turned into an examination of the four Greek words for “love” that we translated into one in English.
Affection (storge) 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.
Friendship (philia) is a strong bond existing between people who share a common interest or activity. Lewis explicitly says that his definition of friendship is narrower than mere companionship: friendship in his sense only exists if there is something for the friendship to be "about". He calls Companionship a matrix for friendship, as friendship can rise in the context of both. Friendship is the least natural of loves, states Lewis; i.e., it is not biologically necessary to progeny like either affection (e.g., rearing a child), eros (e.g., creating a child), or charity (e.g., providing for a child). It has the least association with impulse or emotion.
Eros is love in the sense of 'being in love'. This is distinct from sexuality, 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. This is good because it promotes appreciation of the beloved regardless of any pleasure that can be obtained from them. It can be bad, however, because this blind devotion has been at the root of many of history's most abominable tragedies. In keeping with his warning that "love begins to be a demon the moment [it] begins to be a god", he warns against the danger of elevating eros to the status of a god.
Charity (agapē) is an unconditional love directed towards one's neighbor which is not dependent on any lovable qualities that the object of love possesses. Agape 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. Lewis warns that those who exhibit charity must constantly check themselves that they do not flaunt—and thereby warp—this love ("But when you give to someone, don't tell your left hand what your right hand is doing."—Matthew 6:3), which is its potential threat.
All of us express these different types of love in some way to our family, friends, co-workers, and complete strangers. Remembering that we love because God first loves us, how will you love others today?
