The vigor of civilized societies is preserved by the widespread sense that high
aims are worth-while.  Vigorous societies harbor a certain extravagance of
objectives, so that men wander beyond the safe provision of personal
gratifications.  All strong interests easily become impersonal, the love of
a good job well done.  There is a sense of harmony about such an accomplishment,
the Peace brought by something worth-while.
- Alfred North Whitehead, 1963, in "The History of Manned Space Flight"
