One last passage from Hannah Arendt’s Between Past and Future:

The modern age, with its growing world-alienation, has led to a situation where man, wherever he goes, encounters only himself. All the processes of the earth and the universe have revealed themselves either as man-made or as potentially man-made. These processes, after having devoured, as it were, the solid objectivity of the given, ended by rendering meaningless the one over-all process which originally was conceived in order to give meaning to them, and to act, so to speak, as the eternal time-space into which they could all flow and thus be rid of their mutual conflicts and exclusiveness. This is what happened to our concept of history, as it happened to our concept of nature. In the situation of radical world-alienation, neither history nor nature is at all conceivable. This twofold loss of the world — the loss of nature and the loss of human artifice in the widest sense, which would include all history — has left behind it a society of men who, without a common world which would at once relate and separate them, either live in desperate lonely separation or are pressed together into a mass. For a mass-society is nothing more than that kind of organized living which automatically establishes itself among human beings who are still related to one another but have lost the world once common to all of them.
