The void in local administration and power which was left when the noblesse migrated to Paris and became a court plutocracy, was filled by the government employés, to whom alone the French peasant looked for any attempt at honest administration. They were the heralds of a centralised empire. The same subterraneity of advance is to be traced in the progress of thought. For instance, the Reformation and the overthrow of Scholasticism was a great and precise epoch, but the preparations for this bursting into life were being conducted while we were within the husk of scholasticism

St. Martin’s-le-Grand is a warren, Mount Pleasant a veritable honeycomb—a positive castle of Otranto with, in place of subterraneities, a hidden, circling passage upon every floor.

Let us not make a misty, swift, cavelike terror of the unknown and a meek thing of the known. The known has just as many terrors and subterraneities as the unknown, for the known is not completely known either: all reality is mysterious.

But while the idea of an underground fascinated readers and writers, it had not achieved definitional stability. Rather, the texts I examine proliferate dif­ferent versions of the underground that clustered in proximity to one another, a loose assemblage of disparate subterraneities.
