The Psychology of Peoples and Masses is an immortal book, first published back in 1895 and still relevant today. On its basis, more and more advertising, political and media technologies have been created, are being created and will be created. This is a publication that any politician, journalist, PR specialist or just a person who does not want to become a dumb victim of propaganda should know by heart. Dogma ideas and religion as a way of influencing the masses, the influence of propaganda on the mood of the crowd, ways of instilling in the masses any, even the most harmful and destructive, ideas, these are just a few of the brilliant and cynical insights of Gustave Lebon, a man who, among other things, is the author of the aphorisms "The masses respect only strength" and "The crowd goes not to those who give it evidence, but to those who give it an illusion that seduces it."
