Bismarck, Reflections, v1, p.15

"I certainly do assume that official decisions do not gain in honesty and moderation by being arrived at collectively; for apart from the fact that, in the case of voting by majority, arithmetic and chance take the place of logical reasoning, that feeling of personal responsibility, in which lies the essential guarantee for the conscientiousness of the decision, is lost directly it comes about by means of anonymous majorities", Reflections and Reminiscences (1898)
