The story was strange, yet I believed him. Keokotah did not lie. What he told me was what he saw, but what is it we see? Is it not often what we expect to see? Or imagine we see? He was frightened, so what part was reality and what part was imagination ? Sakim had taught me to be wary of evidence given by others, for in all evidence there is some interpretation. The eyes see, the mind explains. But does the mind explain correctly ? The mind only has what experience and education have given it, and perhaps that is not enough. because one has seen does not mean one knows.
