Lovers scarcely know each other and are more in love with love than with each other. Death always intervenes before there is any significant chance for two people to know each other as they really are. Death, therefore, obscures the need for [the] self-giving kind of love (agape) to supplement and save this romantic love (eros) from its essential preoccupation with self and its idealized projections. The end or destiny of romantic love as a religion is always death, either of the love or of the lovers. Thus death obscures for its adherents the essential self-centeredness and flight that is characteristic of romantic love.
