Russell discusses how governments and institutions use propaganda to shape the beliefs and actions of citizens. He argues that propaganda is often used to create a sense of unity and to suppress dissent, rather than to inform and educate the public. This can lead to a situation where people are unwilling or unable to question the status quo, which can be detrimental to the progress of society. Overall, "Free Thought and Official Propaganda" is a powerful critique of the use of propaganda in society and a passionate defence of free thought. It remains a relevant and thought-provoking essay in today's world, where propaganda and the manipulation of information continue to be pressing issues. Read in English, unabridged.
