Julien Crockett interviews Robert Sapolsky at the LARB:
JULIEN CROCKETT: Most of the discoveries you reference in Determined are from the last 50 years, and half are from the last five, pointing towards a recent shift in biology and related fields. How has the answer to the fundamental question in biology—what is life?—changed during your career?
ROBERT M. SAPOLSKY: The main trend I’ve noticed is people arguing about whether viruses are alive or not. Which gets to the mechanistic point: they’re made of the same stuff as the organisms they infect, the same building blocks, all working by the same principles. So there is some sort of continuum with life. At the other end is deciding when something is dead—when does life end? And what does it mean? We have been able to get EEG waves out of a pig’s brain hours after it has been removed. There is also research suggesting that being in a coma is a heterogeneous experience. So brain death is not quite as straightforward as we used to think.
