Thoreau mentions several actual people in Walden, but curiously, he also devotes considerable attention to describing nonexistent or imaginary people. At the beginning of the chapter “Former Inhabitants,” Thoreau frankly acknowledges that in his winter isolation he was forced to invent imaginary company for himself.

This conjuring is the work of his imagination, but it is also historically accurate, since the people he conjures are based on memories of old-timers who remember earlier neighbors now long gone. Thoreau’s imaginary companions are thus somewhere between fact and fiction, reality and fantasy. When Thoreau describes these former inhabitants in vivid detail, we can easily forget that they are now dead: they seem too real.

Thoreau also manages to make actual people seem imaginary. He never uses proper names when referring to friends and associates in Walden, rendering them mythical. After Thoreau describes Alex Therien as a Homeric hero, we cannot help seeing him in a somewhat poetic and unreal way, despite all the realism of Thoreau’s introduction.

Thoreau doesn’t name even his great spiritual teacher, Emerson, but obliquely calls him the “Old Immortal.” The culmination of this continual transformation of people into myths or ideas is Thoreau’s expectation of “the Visitor who never comes,” which he borrows from the Vedas, a Hindu sacred text. This remark lets us see how spiritual all of Thoreau’s imaginary people are. The real person, for him, is not the villager with a name, but rather the transcendent soul behind that external social persona.
