QUOTE : According to my great-uncle, the lands that had emerged were a limited phenomenon: they were going to disappear just as they had cropped up or, in any event, they would be subject to constant changes: volcanoes, glaciations, earthquakes, upheavals, changes of climate and of vegetation. And our life in the midst of all this would have to face constant transformations, in the course of which whole races would disappear, and the only survivors would be those who were prepared to change the bases of their existence so radically that the reasons why living was beautiful would be completely overwhelmed and forgotten.
