This examination of sedition through the ages includes work on Socrates, the early Christian martyrs, the Utopian movement and political assasination. Constitutional change in England is compared to violent revolution in France, the theories of Marx and Freud, and the tactics of terrorists. The authors ask what it is that drives people to sedition and what the influence of rebellious movements has been. They also consider the reasons why some revolutionaries of the past are honoured while those who are involved in similar activities today are far more generally reviled. The book accompanies an eight-part radio series.
