Hello to the list.  Could someone please assist me?  I am doing some research
and am using a passage from V. that reads something like this:  "Life's
single lesson is that there is more uncertainty to life than man can
comprehend in a lifetime, and stay sane." [Please forgive me if I don't have
it quoted exactly right.]  In order to quote it, however, I need to know what
page it appears on.  Does anyone know where it might be?  Thanks.
