tMoP, Chap 11..The Walk

[Mark Kohut]

p 138..."familiar moral tangle"...which D. says should disturb him more for
no longer disturbing him....The suffering Christian knows he is sinning...it is, in this way, a habit...an aspect of him now.

p 139..."eternal lodger"....surely an allusion to Dostoevsky's novella,
The Eternal Husband: http://www.randomhouse.com/catalog/display.pperl?isbn=9780553214444...unwritten yet in Dosteovsky's real life, therefore 
another foreshadowed work in TMoP, like The Demons.
