In case this blog is seeming a bit too frivolous lately, here's a short quote from Simon Critchley's brilliant Book of Dead Philosophers, from his entry on Lucretius. (Something for Aubrey de Grey, Ray Kurzweil and other modern techno-immortalists to think about.)
What is a year or a decade more or less in comparison to the length of time spent dead? Viewed from the standpoint of eternity, what Spinoza calls sub specie aeternitatis, life's brevity or longevity is nothing in comparison to the eternity of our death. Moreover, this eternity is nothing to fear, but is the basis for contentment and calm.
Critchley takes as his starting point in this book the saying from Cicero, echoed by others through the ages, that "to philosophize is to learn how to die."
