offspring of solitude and delirium
Walton is taking very seriously the notion of the living dead whom Victor accounted a "guiding spirit" (III:7:26
) as he embarked on the Arctic ice fields. Yet what he appears to be telling his sister and her readers here is that Victor's only solace is in madness, and that for so deeply alienated a creature madness is preferable to sanity. If by this statement he is recognizing that Victor is actually mad, it raises considerable questions about what constitutes the truth contained by either narrative—Victor's, certainly, but also his own which relies exclusively on Victor's for its authority.
