Sam Parnia's medical specialty at the New York University Langone Health System is resuscitation. He also directs large clinical studies of heart attacks (cardiac arrest). That has brought him into contact with a lot of people who are on the brink. It has also strengthened his conviction that near-death experiences show that death is not the end of human consciousness. Hence his new book, Lucid Dying (Hachette 2024). From early on, he was puzzled by the relationship between the mind and the brain. He came to see that the message "from science" was not what he had been led to expect. "Although life and death remain a mystery, science is showing that contrary to what some philosophers, doctors, and scientists have argued for centuries, neither biological nor mental processes end in an absolute sense with death," [he said]. "There is much more to be discovered, but science does ... suggest that our consciousness and selfhood are not annihilated when we cross over into death and into the great unknown. In death, we may also come to discover that each of our actions, thoughts, and intentions in life, from the most minute, to the most extreme, do matter." Many believe that science proves " and must prove " that life beyond death is impossible. But it is difficult for science to refute, for example, veridical near-death experiences, where experiencers recount events that they could not have observed under natural circumstances.
