"I saw in the Soviet Union many opponents of the regime. I visited a dozen prisons — the political sections among them. I saw considerable of the work of the OGPU. I heard a good many stories of severity, even of brutality, and many of them from the victims. While I sympathized with personal distress I just could not bring myself to get excited over the suppression of opposition when I stacked it up against what I saw of fresh, vigorous expressions of free living by workers and peasants all over the land. And further, no champion of a socialist society could fail to see that some suppression was necessary to achieve it. It could not all be done by persuasion."
