The brain-death question, as you know, is not simply the life and death issue involved in organ transplants and the multibillion dollar industry that drives it. If the human person is holistically "I" [and experienced as such] and not reducible to the hylomorphic dualism of soul/body, much less to body/brain, then the ramifications of the outcome become large. It would then be the question of the future global culture and the epistemology (and its source) that drives it. Let me quote from Benedict XVI as Joseph Ratzinger in his conversation with Marcello Pera:
“There are two opposing diagnoses on the possible future of
“Spengler’s ‘biologistic’ thesis attracted fierce opponents during the period between the two wars, especially in Catholic circles. Arnold Toynbee reserved harsh words for it, in arguments too readily ignored today. Toynbee emphasized the difference between technological-material progress and true-progress, which he defined as spiritualization. He recognized that the Western world was indeed undergoing a crisis, which he attributes to the abandonment of religion for the cult of technology, nationalism, and militarism.

“The essential problem of our times, for
The outcome of the brain-death issue will not come ultimately from argumentation but from a change in the paradigm of experiences. Ultimately, it can only be an experience of self-transcendence as in the Christian faith that can restore the consciousness of the "I" of the person and his transcendent dignity. However, argumentation will be absolutely necessary to lead the mind to the aporia that results from the stagnation of reason that has wilted under the burden of a technological culture of nothing but facts and data bases.
An indispensable reading to make this paradigm shift is Wojtyla's "Subjectivity and the Irreducible in the Human Person" Person and Community Lang (1993) 209-217. And then, further: J. Ratzinger, "Introduction to Christianity," Ignatius (2004) 183-184.
