Indifference to objective truth is encouraged by the sealing-off of one part of the world from another, which makes it harder and harder to discover what is actually happening.

Context

“When one considers the elaborate forgeries that have been committed in order to show that Trotsky did not play a valuable part in the Russian civil war, it is difficult to feel that the people responsible are merely lying. More probably they feel that their own version was what happened in the sight of God, and that one is justified in rearranging the records accordingly. Indifference to objective truth is encouraged by the sealing-off of one part of the world from another, which makes it harder and harder to discover what is actually happening. There can often be a genuine doubt about the most enormous events. For example, it is impossible to calculate within millions, perhaps even tens of millions, the number of deaths caused by the present war.” source
