The Russian literary critic Mikhail Bakhtin wrote his essay "Epic and Novel" in 1941. It was not a good time to be in Russia, and certainly not in Moscow. The poet Osip Mandelstam had been exiled by Stalin eight years before, and was now three years dead. Hitler was invading. In his lifetime, Bakhtin had already been exiled by the secret police and sent to Kazakhstan; he lost his leg due to disease in 1938. Those were darker times than anything we have known.
One can ask why on earth Bakhtin was writing expansive literary criticism on Rabelais, Dostoevsky, and the history and theory of the novel in the middle of all of this. I don't pretend to know the answer. I don't claim that it was a good idea. I do think that Bakhtin arrived at insights that sustained him and still explain why you might want novels or comedies—or even just scholarship on novels and comedies—in times like his.
