Objectification and Human Dignity. Kant's Marriage Law and the Law of domestic Cohabitation

Within The Doctrine of Right in The Metaphysics of Morals Kant deals with the social institution of household, the Domestic Society, next to Property Right and Contract Right as part of the Private Right. The juridical problem to solve is the question to what extent human beings can be entitled to dispose persons as a “belonging” at all. This problem of Reification insistently arises with regard to the relation of partners in a marriage: According to Kant, Sexuality as a consumption by which human beings make use of themselves as of things is reconcilable with the dignity of humanity only under the condition of marriage. By marrying, persons acquire one another reciprocally, so that they aren't in an external relation to one another any more. However, in contrast to this strict juridical reciprocity of the sexes in a marriage there is no corresponding equality concerning the regime of the household. Hence, with his anthropology of the sexes Kant unintentionally implements teleological patterns of argumentation into the Right of pure practical reason.
