Did Descartes doom Terri Schiavo?  “The plea … to prolong Ms. Schiavo’s feeding, against the wishes of her husband or what courts determined to be her own expressed inclinations, echoed the teachings of Aristotle, who considered existence itself to be inviolable. On the other side, the argument that Ms. Schiavo’s life could be judged as not worth living echoed Descartes, the Enlightenment philosopher who defined human life not as biological existence – which might be an inviolable gift from God – but as consciousness, about which people can make judgments.”
