There must be much for a philosopher to say about such a vivid manifold phenomenon as "love"
There are said to be different forms of love: agape (universal love), philautia (self-love), storge (familial love), philia (platonic love), eros (romantic love) and their respective verb forms. On occasion, some are interchangeable, but they are not seen as strong synonyms
The image of love is an ascent motivated by a hierarchy of increasing value for the lover or their beloved. The more erotic the love, the more valuable it is. Two people may say they are "just friends." They may be grossed out by the thought of themselves as "more than just friends." That's because philia does not transcend the "ick" of commitment or intimacy. It's eros that transcends the "ick." It accepts everything about the other, even the "icky" parts of their body. Its unions tend to be wholly faithful or maintained loyally and eagerly
Despite the hierarchy, love, in all shapes or forms, is the joy and sorrow we experience with others or ourselves
Or is it? What if love doesn't exist? Or what if there are no different forms of love? Is there any philosopher that does not believe in the existence of love?
