I saw this play as a kind of trailer for L'Homme révolté
... it explores the same themes, but in a much more accessible way. The central paradox is the conflict of intuitions about the ethics of revolution. The rebel is sickened by the injustice of the world, and takes responsibility for creating justice by the use of violence - in this case, the assassination of the Grand Duke. However, this arguably makes him just as bad as the oppressors. Les Justes
is, as one would expect, beautifully written, and is very economical in working you through the different sides of the question and engaging your emotions. Given that Camus played an active part in the Resistance, it is not an academic exercise - these must have been issues that disturbed him a great deal. I kept wondering whether the 9/11 terrorists had these kinds of discussions. Full points to Camus for writing a play that's just as relevant now as when he wrote it.
