This means two things. First it means that the man claims his share of the woman’s body or, more generally, that one person claims a right to the other, claims to be entitled to possess the other, and thereby denies and destroys the creaturely nature of the other person. This obsessive desire [Sucht] of one human being for another finds its primordial expression in sexuality. The sexuality of the human being who transgresses his or her boundary is a refusal to recognize any limit at all; it is a boundless obsessive desire to be without any limits. Sexuality is a passionate hatred of any limit. It is extreme lack of respect for things-as-they are [Unsachlichkeit]; it is self-will, an obsessive but powerless will for unity in a divided [entzweiten] world. It is obsessive because it knows of a common human being from the beginning; it is powerless because in losing his or her limit a human being has finally lost the other person. Sexuality seeks to destroy the other person as a creature, robs the other person of his or her creatureliness, lays violent hands on the other person as one’s limit, and hates grace.By destroying the other person one seeks to preserve and reproduce one’s own life. Human beings create by destroying; in sexuality the human race preserves itself while it destroys. Unbridled sexuality is therefore destruction κατʼ ἐξοχήν; it is a mad acceleration of the fall, of the downward drop. It is affirming oneself to the point of self-destruction. Obsessive desire [Sucht] and hate, tob and ra—these are the fruits of the tree of knowledge.
From this dividedness, however, there now follows a second thing, humankind’s covering itself up. Human beings with no limit, in their hatred and in their obsessive desire, do not show themselves in their nakedness. Nakedness is the essence of unity, of not being torn apart, of being for the other, of respect for what is given, of acknowledging the rights of the other as my limit and as a creature. Nakedness is the essence of being oblivious of the possibility of robbing others of their rights. Nakedness is revelation; nakedness believes in grace. Nakedness does not know it is naked, just as the eye does not see itself or know about itself. Nakedness is innocence."
