In Europe today there are plenty of people who think they have learnt to do without dogmas, yet it is precisely the freethinkers and the materialists who are the worst fanatics for dogmas. The dogma of materialism is much more oppressive than any other. The infallibility of the Pope is no longer valid for many people, but instead we have the infallibility of the professor. Even the most liberal-minded, whatever they may say to the contrary, are victims of the dogmas of materialism. Think of the dogmas which burden lawyers, doctors and so on. Every university professor teaches his own dogma. Or think how people suffer from the dogma of the infallibility of public opinion, of the newspapers!
