Structure

The novel is divided into six parts, with an epilogue. The notion of "intrinsic duality" in Crime and Punishment has been commented upon, with the suggestion that there is a degree of symmetry to the book. Edward Wasiolek, who has argued that Dostoevsky was a skilled craftsman, highly conscious of the formal pattern in his art, has likened the structure of Crime and Punishment to a "flattened X", saying:

Parts I–III present the predominantly rational and proud Raskolnikov: Parts IV–VI, the emerging "irrational" and humble Raskolnikov. The first half of the novel shows the progressive death of the first ruling principle of his character; the last half, the progressive birth of the new ruling principle. The point of change comes in the very middle of the novel.

This compositional balance is achieved by means of the symmetrical distribution of certain key episodes throughout the novel's six parts. The recurrence of these episodes in the two halves of the novel, as David Bethea has argued, is organized according to a mirror-like principle, whereby the "left" half of the novel reflects the "right" half.

The seventh part of the novel, the Epilogue, has attracted much attention and controversy. Some of Dostoevsky's critics have criticized the novel's final pages as superfluous, anticlimactic, unworthy of the rest of the work, while others have defended it, offering various schemes that they claim prove its inevitability and necessity. Steven Cassedy argues that Crime and Punishment "is formally two distinct but closely related, things, namely a particular type of tragedy in the classical Greek mold and a Christian resurrection tale". Cassedy concludes that "the logical demands of the tragic model as such are satisfied without the Epilogue in Crime and Punishment... At the same time, this tragedy contains a Christian component, and the logical demands of this element are met only by the resurrection promised in the Epilogue".
