We are seldom able to trace our individual superstitions to any definite cause, nor can we often account for the peculiar sensations developed in us by the inexplicable and mysterious incidents in our experience. Much of the timidity of childhood may be traced to early training in the nursery, and sometimes the moral effects of this weakness cannot be eradicated through a lifetime of severe self-control and mental suffering. The complicated disorders of the imagination which arise from superstitious fears can frequently be accounted for only by inherited characteristics, by peculiar sensitiveness to impressions, and by an overpowering and perhaps abnormally active imagination. I am sure I am confessing to no unusual characteristic when I say that I have felt from childhood a certain sentiment or sensation in regard to material things which I can trace to no early experience, to the influence of no literature, and to no possible source, in fact, but that of inherited disposition. The sentiment I refer to is this: whatever has belonged to or has been used by any person seems to me to have received some special quality, which, though often invisible and still oftener indefinable, still exists in a more or less strong degree, according to the amount of the impressionable power, if I may call it so, which distinguished the possessor. I am aware that this sentiment may be stigmatized as of the school-girl order; that it is, indeed, of the same kind and class with that which leads an otherwise honest person to steal a rag from a famous battle flag, a leaf from an historical laurel wreath, or even to cut a signature or a title-page from a precious volume; but with me the feeling has never taken this turn, else I should not have confessed to the possession of it. Whatever may be said or believed, however, I must refer to it in more or less comprehensible terms, because it may explain the conditions, although it will not unveil the causes, of the incidents I am about to describe with all honesty and frankness.
