Just FYI: The link Prof. Pessin supplied isn't an essay by Thomas Nagel. It appears to be a paper concerning Nagel's work on the meaning of life, a paper written by a student (Lucas Beerekamp) for a course at a university in the Netherlands. Chapter 1o of Nagel's introductory book What Does It All Mean? (1987) is entitled "The Meaning of Life." Perhaps that's what Prof. Pessin meant to refer to (although it's barely seven short pages). More likely he meant to refer to Nagel's famous Journal of Philosophy article, "The Absurd" (1971).
