“Neither Stalinism nor Fascist totalitarianism would have been possible without the transmogrified Marxism, that infilled both.”

The Mike Wallace Interview (1958)
Context: The people that weren't traditionally religious, conventionally religious, had a religion of their own in my youth. These were liberals who believed in the idea of progress or they were Marxists. Both of these secular religions have broken down. The nuclear age has refuted the idea of progress and Marxism has been refuted by Stalinism. Therefore people have returned to the historic religion. But now when the historic religions give trivial answers to these very tragic questions of our day, when an evangelist says, for instance, we mustn't hope for a summit meeting, we must hope in Christ without spelling out what this could mean in our particular nuclear age. This is the irrelevant answer, when another Evangelist says if America doesn't stop being selfish, it will be doomed. This is also a childish answer because nations are selfish and the question about America isn't whether we will be selfish or unselfish, but will we be sufficiently imaginative to pass the Reciprocal Trade Acts.
