"Let those who complain that too much money is being spent on abstract
knowledge while people are starving remember this: The alternative to
knowledge is savagery. Their very existence as stowaways on the voyage
of civilization is owing to advances in science which permit some to
live without doing their share of the work. Let them be tolerant, then,
lest by encumbering the useful ones they destroy the thing which keeps
them alive." -- George Ellery Hale
