"Tho' much is taken, much abides; and tho'
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."
From Ulysses by Lord Alfred Tennyson
I'm no limey, but that's some stirring stuff, what!I think these lines were also quoted in Skyfall; though back in the nineties in a place once called Calcutta, there used to be a Physics teacher who'd open his first class with preceding verse from the same poem;
"A bringer of new things; and vile it were
For some three suns to store and hoard myself,
And this gray spirit yearning in desire
To follow knowledge like a sinking star,
Beyond the utmost bound of human thought."
