Have already seen the movie but just remembered this was quoted by M to a select committee in the new james Bond Skyfall movie which is out today in the UK.
Rather poignant for me with personal circumstances so thought I would share as I love it
Though much is taken, much abides; and though
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 (1809-1892) 1833
