“The concerns for nonviolence, sustainable development, justice, and peace, and care for our environment are of vital importance for humanity,” the pope said. “They cannot, however, be understood apart from a profound reflection upon the innate dignity of every human life from conception to death,” he said in an address to more than 140,000 people at his first appearance at World Youth Day here.
There is nothing innate about human dignity.
Ascribing "dignity" (whatever that is) to every human life from conception to death is to preempt a whole range of actions that make good sense. If one buys into the nonsensical idea of "inherent human dignity", then one can't accept the logic of protection of the commons, which implies only that problems are worse later.
Inherent human "dignity" is a vague and stupid concept. Morality is relative. The pope is wrong.
