To what problem does Miller allude when he writes about the cast of a movie giggling as they watch Hitler on film or those of us today watching McCarthy on film?

The problem would be that we have ceased to be afraid and no longer understand the fear that history produced in humans during their own lives.

"Fear doesn't travel well; just as it can warp judgment, its absence can diminish

memory's truth. What terrifies one generation is likely to bring only a puzzled smile to the next."
