of the Brahmans, Greeks, or Romans, seem quite unconscious of the many centuries that must needs have passed over the heads of the Patagonians of the present day as well as of the Greeks at the time of Homer. They look upon the Patagonians as the _tabula rasa_ of humanity, and they forget that even if we admitted that the ancestors of the Aryan race had once been more savage than the Patagonians, it would not follow that their savagery was identical with that of the people of Tierra del Fuego. Why should not the distance between Patagonian and Vedic Rishis have been at least as great as that between Vedic Rishis and Homeric bards? If there are ever so many kinds of civilized life, was there only one and the same savagery? To take, for instance, the feeling of fear; is it likely that we shall find out whether it is innate in human nature or acquired and intensified in each generation, by shaking our fists in the face of a little baby, to see whether it will wink or shrink or shriek? Some children may be more fearless than others, but whether that fearlessness arises from ignorance or from stolidity is again by no means easy to determine. A burnt child fears the fire, an unburnt child might boldly grasp a glowing coal, but all this would not help us to determine whether fear is an innate or an acquired tendency or habit. All I can say for myself is that my young life and even my later years were often rendered miserable by the foolish stories of one of my grandmothers, and that I had to make a strong effort of will before I could bring myself to walk across a churchyard in the dark. This shows how much our character is shaped by circumstances, even when we are least aware of it. I did not believe in ghosts and I was not a coward, but I felt through life a kind of shiver in dark passages and at the sound of mysterious noises, and the mere fact that I had to make an effort to overcome these feelings shows that something had found its way into my mental constitution that ought never to have been there, and that caused me, particularly in my younger days, many a moment of discomfort.
