C. P. Snow writing in 1959 about the change brought about by the scientific revolution. (From The Two Cultures.)
The disparity between the rich and the poor [countries] has been noticed. It has been noticed, most acutely and not unnaturally, by the poor. Just because they have noticed it, it won’t last for long. Whatever else in the world we know survives to the year 2000, that won’t. Once the trick of getting rich is known, as it now is, the world can’t survive half rich and half poor. It’s just not on.
