It is not, however, intended to assert that the contributions of the entire region covered in this collection are identical in character. On the contrary, it will be seen that the record made in certain districts, as for example in Newfoundland and among the Mountain Whites of the Alleghanies, presents superstition as more primitive and active than in the eastern United States. But this vitality is only to be regarded as the persistence of a stock once proper to English-speaking folk, and by no means as indicating a diversity of origins. The chief value of a collection such as the present consists in the light it may be made to cast on the history of mental processes; in other words, on its psychologic import. To appreciate this value, it is needful to understand the quality in which superstition really consists. This distinguishing characteristic is obscured by the definitions of English dictionaries, which describe superstition as a disease, depending on an excess of religious sentiment, which disposes the person so affected to unreasonable credulity. In the same spirit, it has been the wont of divines to characterize superstition and unbelief as opposite poles, between which lies the golden mean of discreet faith. But this view is inadequate and erroneous. The manner of conception mentioned has been borrowed from Latin and Greek writers of the Roman republic and of the Imperial period. In primitive Roman usage, _superstitio_ and _religio_ were synonyms; both, perhaps, etymologically considered, expressed no more than that habit of careful consideration with which a prudent man will measure the events which encounter him, and determine his conduct with a view to consequences. _Superstitio_ may have indicated only the _overstanding_ of the phenomenon, the pause necessary for its deliberate inspection. By Cicero a distinction was made; the word was now employed to designate a state of mind under the influence of supernatural terrors. In the Greek tongue a similar conception was expressed by the word _deisidaimonia_, or fear of daemons, a term in bad odor as associated with practices of Oriental temple worship representing primitive conceptions, and therefore odious to later and more enlightened Hellenic thought. Established as a synonym of the Greek noun, _superstitio_ received all the meaning which Plutarch elaborated as to the former; the idea of that excellent heathen, that true piety is the mean between atheism and credulity, has given a sense to the word superstition, and become a commonplace of Christian hortatory literature.
