History is natural selection. Mutant versions of the past struggle for dominance; new species of fact arise,and old, saurian truths go to the wall, blindfolded and smoking last cigarettes. Only the mutations of the strong survive. The weak, the anonymous, the defeated leave few marks: field-patterns, axe-heads, folk-tales, broken pitchers, burial mounds, the fading memory of their youthful beauty. History loves only those who dominate her: it is a relationship of mutual enslavement.
