Nussbaum has argued that the topic of objectification is not only important to sexuality, which has been discussed at length, but to the Marxist view on capitalism and slavery. Nussbaum argues that potentially not all forms of objectification are inherently negative acts and that objectification may not always be present when one of the seven properties is present.
- Reduction to body – the treatment of a person as identified with their body, or body parts;
- Reduction to appearance – the treatment of a person primarily in terms of how they look, or how they appear to the senses;
- Silencing – the treatment of a person as if they are silent, lacking the capacity to speak.
