Superstition, the product of ignorance of causes, of the proneness to seek the solution of phenomena out of and beyond nature, and of the consequent natural but unreasoning dread of the Unknown and Invisible (ignorantly termed the supernatural), is at once universal in the extent, and various in the kinds, of its despotism. Experience and reason seem to prove that, inherent to and apparently coexistent with the human mind, it naturally originates in the constitution of humanity: in ignorance and uncertainty, in an instinctive doubt and fear of the Unknown. Accident may moderate its power among particular peoples and persons; and there are always exceptional minds whose natural temper and exercise of reason are able to free them from the servitude of a delusive imagination. For the mass of mankind, the germ of superstition, prepared to assume always a new shape and sometimes fresh vigour, is indestructible. The severest assaults are ineffectual to eradicate it: hydra-like, far from being destroyed by a seeming mortal stroke, it often raises its many-headed form with redoubled force.
