Existentialism via Solzhenitsyn and the Gulag
Professor Jordan Peterson discusses the nature of the thinking behind the Marxist terror of the Soviet Union. You should view this if you want to understand the effects of Marxist ideology on a nation. Peterson comments:
In this lecture, I explore the dreadful socio-political consequences of the individual inauthentic life: the degeneration of society into nihilism or totalitarianism, often of the most murderous sort, employing as an example the work/death camps of the Soviet Union.
Buy The Gulag Archipelago by Aleksandr Solzhenitsyn. It is arguably the most important book of the twentieth century.
