Czeslaw Milosz on the mobile life:

Throughout all my early childhood, rivers, towns and land­scapes followed one another at great speed. My father was mobilized to build roads and bridges for the Russian Army, and we accompanied him, traveling just back of the battle zone, leading a nomadic life, never halting longer than a few months. Our home was often a covered wagon, sometimes an army railroad car with a samovar on the floor, which used to tip over when the train started up suddenly. Such a lack of stability, the unconscious feeling that everything is tempo­rary, cannot but affect, it seems to me, our mature judgments, and it can be the reason for taking governments and political systems lightly. History becomes fluid because it is equated with ceaseless wandering.
