Habitance is the quality of a thing which inhabits a place, and of that space being inhabited by same said thing. Habitance, therefore, is inherent in all habitats, whether or not these same habitats are being inhabited — filled! — by any number of accidental-contingent, existent thing.
Habitance , though, is meant to be the particular manner of inhabiting, of habitation, of the Habitant people, in the St-Lawrence Lowlands and the Seigniorial System of land distribution, in history, in North America. Habitance, then, is said to be the special “thrownness” of the Habitant people.
