Deja Vu.

I came across a speech by Oliver Wendall Holmes delivered for Memorial Day, May 30, 1884, at Keene, NH, titled "In Our Youth Our Hearts Were Touched With Fire"
I was struck by the following passage because it sounded very similar to a line in the 1960 inaugural address of JFK.

...it is now the moment when by common consent we pause to become conscious of our national life and to rejoice in it, to recall what our country has done for each of us, and to ask ourselves what we can do for the country in return.
Oliver Wendall Holmes
