It is science alone that can solve the problems of hunger and poverty, of insanitation and illiteracy, of superstition and deadening custom and tradition, of vast resources running to waste, or a rich country inhabited by starving people...

Medical costs are of concern, both in developing and developed countries.

History is written by the victors.
