To the other person, who looks at me from the outside, I seem an object, a thing; my subjectivity with its inner freedom escapes his gaze.

The lover wishes to possess the beloved, by the freedom of the beloved (which is his or her human essence) cannot be possessed; hence, the lover tends to reduce the beloved to an object for the sake of possessing it. Love is menaced always by a perpetual oscillation between sadism and masochism: In sadism I reduce the other to a mere lump, to be beaten and manipulated as I choose, while in masochism I offer myself as an object, but in an attempt to entrap the other and undermine his freedom.
