Abstract
The essay begins by discussing different ways of evaluating and making sense of the Soviet Revolution from Crane Brinton to Hannah Arendt. In a second part, it analyses the social, political and intellectual background of tsarist Russia that made the revolution possible. After a survey of the main changes that occurred in the Soviet Union, it appraises its ends, the means used for achieving them, and the unintended side-effects. The Marxist philosophy of history is interpreted as an ideological tool of modernization attractive to societies to which the liberal form of modernization was precluded.
