What we call isolation in the political sphere, is called loneliness in the sphere of social intercourse.Isolation and loneliness are not the same"...."While isolation concerns only the political realm of life, loneliness concerns life as a whole. Totalitarian government, like all tyrannies, certainly could not exist without destroying the public realm of life, that is, without destroying, by isolating men, their political capacities.But totalitarian domination as a form of government is not content with this isolation and destroys private life as well. it bases its self on loneliness, on the experience of not belonging to the world at all, which is the most radical and desperate experiences of man
