What is Robert Frost's attitude in his poem "Desert Places"?

In "Desert Places," Robert Frost takes a scene from nature
and uses it as a springboard for a philosophical idea.

The
poem begins with a description of a field filling up with snow at
night:

Snow falling and night falling fast, oh,
fast
In a field I looked into going past,
And the ground almost
covered smooth in snow,
But a few weeds and stubble showing last.

The poet proceeds to
interpret the scene before him as a symbol of loneliness and
emptiness:

And
lonely as it is, that loneliness
Will be more lonely ere it will be less
-
A blanker whiteness of benighted snow
WIth no expression, nothing
to express.

The
poet then moves from the snowy scene on Earth to the great "empty spaces / Between
stars"; he says that no-one can scare him with those empty spaces
because:

I
have it in me so much nearer home
To scare myself with my own desert places.

Frost seems to be saying
that one does not have to travel to outer space on a solo rocket mission to exprerience
loneliness.  Rather, loneliness is part of the human condition.  Each person is, by
definition,  separated from all other people and thus has his or her "own desert
places."
