"Ivan Karamazov ... does not absolutely deny the existence of God. He refutes Him in the name of a moral value. ... God, in His turn, is put on trial. If evil is essential to divine creation, then creation is unacceptable. Ivan will no longer have recourse to this mysterious God, but to a higher principle – namely, justice. He launches the essential undertaking of rebellion, which is that of replacing the reign of grace by the reign of justice."
