Now the trumpet summons us again--not as a call to
arms, though arms we need--not as a call to battle,
though embattled we are--but a call to bear the
burden of a long twilight struggle, year in and year
out, 'rejoicing in hope, patient in tribulation'--a
struggle against the common enemies of man:
tyranny, poverty, disease, and war itself.

~ John F. Kennedy (1917-1963)
Inaugural address, 20 Jan. 1961
