Lovers do not relate to their beloveds as seats of valuable qualities that would be replaceable for anyone with relevantly similar or more valuable qualities. Instead, lovers take their beloveds to be irreplaceable. This has been noted frequently in the current debate on love and different theories of love have offered different explanations for the phenomenon. In this paper, I develop a more complex picture of what is involved in lovers taking their beloveds to be irreplaceable. I argue that in (...) order to account for the beloved’s irreplaceability, a theory of love must meet two conditions: it must explain the subjective aspect as well as the moral aspect of the beloved’s irreplaceability. I show that current theories of love fail to meet these conditions, either one or both of them, and I offer an alternative account that does - an account according to which love is understood as a special kind of desire for the beloved as a person. The aim of this paper is twofold: first, to give a more nuanced picture of the beloved’s irreplaceability, acknowledging in particular that there is a moral aspect to the phenomenon that has not been attended to thus far; second, to introduce and motivate a new desire-based account of love.
