Nobel Address (1991)
“I am more and more convinced that taking life over-seriously is a frivolous thing.”
Entry (1952)

Context: I am more and more convinced that taking life over-seriously is a frivolous thing. There is an affected self-dramatizing in the brooding over one's prospects and destiny. The trifling attitude of an Ecclesiastes is essentially sober and serious. It is in closer touch with the so-called eternal truths than are the most penetrating metaphysical probing and the most sensitive poetic insights.
