My definition of human dignity is that every human being is valuable. In the words of the UDHR, human dignity is defined as the idea that every human has inherent worth.
I believe the foundation of dignity lies truly only in our ability to recognize and truly appreciate others’ worth. That worth being infinitesimally small, apparently non-existent or even grossly exaggerated is not up to anybody or even quantifiable. It isn’t based on opinion or value-assessment but rather by recognition of the equal and inalienable rights of all members of humanity. With that in mind, my perspective on the topic of the foundation of the dignity of the human person is that human dignity cannot be shared by a group of people or even religion but rather is a personal characteristic whose appreciation and sharing can only be achieved by accepting no human being has greater or less value than we do. In my opinion, this acceptance is the only foundation of human dignity.
