Whose woods these are I think I know.
His house is in the village though;
He will not see me stopping here
To watch his woods fill up with snow.
My little horse must think it queer
The opening lines set the psychological tone of the poem. Whose woods are these? The speaker THINKS he knows, but he is uncertain. Uncertainty is pervasive through this poem. The speaker seems at first to be referring to a local landowner on whose property the woods lie, but as the poem ultimately suggests, the woods “belong” also to the darker, more impersonal forces of nature. 
 Some have speculated that “Whose” might even refer to God. The impersonal forces of nature have no house in the village. God does, though. He’s got the biggest house: in the context of the poem it would be the church. For readers of different religious persuasions it could be the spiritual presence to which they relate. 
 “The woods” and “the village” create a nature vs. society juxtaposition that highlights the speaker’s isolation. This dichotomy also establishes one of the poem’s major themes: choosing between a looming irrational world (the wild woods) and sensibility and responsibility. Sounds like the summer after senior year of high school.
