In some of my reading this evening, I chanced upon this quotable from T.S. Eliot (page 77, Christianity and Culture):
"Any machinery, however beautiful to look at and however wonderful a product of brains and skill, can be used for bad purposes as well as good: and this is as true of social machinery as of constructions of steel. I think that, more important than the invention of a new machine, is the creation of a temper of mind in people such that they can learn to use a new machine rightly. More important still at the moment would be the diffusion of knowledge of what is wrong—morally wrong—and of why it is wrong."
In some ways, his writings seem out of date, but in other ways, he seems to be able to hit the nail on the head. The Church in the Vatican II Council basically says the same thing, only about modern communications networks, in the decree Inter Mirifica.
