My first reaction was bitter cynicism and a rejection of all the material and spiritual values which mankind had developed in the course of thousands of generations. But at the same time I felt that I should have to overcome that cynicism if I were to survive here in the desert. Cynicism is a sharp enough weapon in the hurly-burly of an overcrowded town; it gives you elbow-room and it also gives you a satisfactory feeling of superiority. But what's the use of elbow-room in a desert? And what's the use of cynicism when the enemies you have to contend with are the broiling sun and the parching winds? When your only aim is to survive amidst the swift, sure-footed, cruel and lovely animals of the desert?
