In Chapter 2, having elaborated the conception of human dignity as empowerment, we compare it with conception of human dignity as constraint that is to be found in the Convention on Human Right and Biomedicine and the Universal Declaration on the Human Genome and Human Right. Here we find human dignity acting as a constraint on free choice. However, this constraint is open to interpretation. On one reading, human dignity constrains by virtue of being a collective good that represents each society’s vision of the kind of society it wants to be. On another reading, the constraint springs from the view that it is as wrong to compromise one’s own dignity as it is to compromise the dignity of others.
