We are not now that strength which in old days
Moved earth and heaven; that which we are, we are;
One equal temper of heroic hearts
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.
-Alfred, Lord Tennyson, Ulysses (66-70) 1833
I remember how vividly blue the September sky was that day. And today the sky seems to be the same impossible blue.
