How does thoreau respond when people ask if he is lonely living alone in the woods

In "Walden; or Life in the Woods" Henry David Thoreau tells us about what is like to live a simple life in the woods. His nearest neighbor is a mile away and there is no house is visible from where he lives. He lives far away from society but feels no melancholy "There can be  no very black melancholy to him who lives in the midst of Nature and  has his senses still." He doesn't feel lonely or oppressed by solitude, moreover, he feels Nature's friendship and support. When he is asked if he is lonely he is tempted to reply that the whole earth is a point in space, and in the Milky Way. What we really need, is not to be near many men but to live close to the source of our lives. “How vast and profound  is the influence of the subtile powers of Heaven  and of Earth!”

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
