Here. For example, Rescher died of incoherence while Spinoza died of substance abuse. Miguel de Unamuno expired from a tragic loss of sense. Plantinga perished of necessity, and Augustine by a Hippo. As you can see, some are nasty and one needn't be dead to have a cause of death assigned. Last I checked, Professor Rescher was still happily scribbling away. And that reminds me of a joke.
A student goes to visit Professor Rescher. Secretary informs her that the good doctor is not available because he is writing a book. Student replies, "I'll wait."
