True science is distinctively the study of useless things. For the useful things will get studied without the aid of scientific men. To employ these rare minds on such work is like running a steam engine by burning diamonds.
I think most of us can remember from our own childhood, just in the Disney cartoons, things that frightened us profoundly. For me it was Bambi, the scene when the forest was on fire. That was something I had nightmares about. I can't imagine being a little kid of eight and seeing Night Of The Living Dead with living corpses eating the flesh of living people.
