Swann's Way, Combray II, pp.251-265

Beginning with "how often, after that day, in the course of my walks along the Guermantes Way"

These are the final pages in part I, Combray and they bring us almost full circle to the narrator's thoughts at the beginning of the work, as though backing out from the more focused view to the more general one at the beginning.

After seeing Mme Guermantes in the church M returns to lamenting his impotence as a writer. He is afraid that he has no talent for his chosen profession and can find nothing to write about. It isn't until a return trip from a walk along the Guermantes Way that his writers block is broken and he writes a snippet on steeples in his view (the steeples of which he writes, not of Combray, are a trio—originally just two, and then a third attempts joins them—bringing to my mind the social triangle). He is relieved to be able to write again. It is a writer's epiphany.

He finishes the description of the Guermantes Way by linking it to feelings of "melancholy" because on nights they take that route, being late after such a long walk his mother is not free to come put him to bed. This is a break in the night-time routine upon which his happiness is dependent. The Guremantes Way embodies the dichotomy between utter happiness and desperate melancholy.

Some meandering thoughts...
I see another difference between the walks now, too, the first (Méséglise or Swann's Way) being connected more with sensuality, the second (Guermantes) with his intellectual (and social?) pursuit, or at least that's how they were depicted in his descriptions. Méséglise is sensual, lower class, country, French, stormy. Guermantes is intellectual, upper class or nobility. So while the Méséglise Way is a confirmation of all that is French and home, the Guremantes Way is what separates him from home and mother and comfort.

And then we're out in his more vague memories and ideas again, with a reminder of the madeleine cake and tea, and a preface to the upcoming memory, "a story which, many years after I had left the little place, had been told me of a love affair in which Swann had been involved before I was born" (p.262).

And finally we leave his sleep walking mind through the same door by which we had entered it, only instead of his confusion over which room he is half asleep in, now the room's true features are coming into focus with day. He is awake and memory is dawning?
