There are many ways to define opposites. This author demands that the "dark mirror" person wants the exact opposite, but that is way too specific in my opinion.<p>Then it's more interesting with cases like William Cowper. Who certainly believed in anything a Christian in his time and place was supposed to believe, including double predestination. It's just that unlike most who believed that, he was convinced he was predestined for hell. He didn't go around doing evil things, of course, what would be the point of that? But he was very, very distressed.<p>Likewise, I think the author underestimates how much Marxist historical materialism was viewed as a hard science in much of the world, until the cold war. There were certainly capitalists who were terrified it was true, but could not see any way out of it for themselves, because just like Cowper's double predestination, orthodox Marxism denies that there is such a thing.
