  MacKinnon too describes objectification in similar terms. She writes: “… A sex object is defined on the basis of its looks, in terms of its usability for sexual pleasure, such that both the looking—the quality of gaze, including its points of view—and the definition according to use become eroticised as part of the sex itself. This is what the feminist concept of ‘sex object’ means” (MacKinnon 1987, 173). She furthermore holds: “A person, in one Kantian view, is a free and rational agent whose existence is an end in itself, as opposed to instrumental.  In pornography women exist to the end of male pleasure” (MacKinnon 1987, 173). Insofar as an individual has only instrumental value, she is clearly not regarded as an end in herself.
