The Rebel, Albert Camus, the master of existentialism, analyzed the spirit of rebellion from the French Revolution to the Russian Revolution. The Jacobans, rebelled against King and God and by making their principles divine, introduced the Reign of Terror.
Nihilism went further and eliminated absolute principles and its rise during the second half of the nineteenth century created terrorists who renounced virtue and principles and who rebelled against reality and history by destroying them. From the killing of gods to the killing of kings, rebellions had ushered in the terrors of Hitler and then of Stalin. The Soviets, in the name of the classless society in the future, a new heaven and a new earth where the lamb and the lion coexist, justified violence to guide the path of civilization, to force the end of history, the Marxist utopia.
Camus stated that absolute freedom leads to injustice and absolute justice stifles freedom and demonstrated it with examples from the French Revolution to the Russian Revolution. And he believed that only through moderation, by limiting freedom with justice and vice versa, could a possible solution emerge.
Events in the past several decades have shown that his statement remains relevant in our time. From Timothy McVeigh to Anders Behring Breivik, we have seen terrorists kill in the name of their freedom, their absolute freedom, and of justice, their notion of absolute justice.
