We humans have bodies in a biological sense. By contrast, we are our bodies in the cultural context of how, normatively, we collectively regard our own bodies and the bodies of others. The biological is given; the cultural, socially constructed. With the rapidly increasing capacity to manipulate future bodies genetically, toward influencing some traits of future bodies, the distinction between nature and culture weakens but hardly vanishes. To be sure, the sphere of human nature has always shared a porous boundary with human culture. Consider several examples of how humans construct culture. Disease, pathology, and medicine have more to do with nature than culture – but they are not culture-free. Another example: “human nature” with respect to what is “normal,” what is “illness,” what is “harm,” and what constitutes a physical disease or cognitive illness, involves elements both natural and cultural. A third example: notions of human freedom, equality, and rights have mostly to do with culture – but they are not nature-free.
