The effects of these discoveries upon miraculous legends are of various kinds. In the first place, a vast number which have clustered around the notion of the irregularity of some phenomenon which is proved to be regular—such as the innumerable accounts collected by the ancients to corroborate their opinion of the portentous nature of comets—are directly overthrown. In the next place, the revelation of the interdependence of phenomena greatly increases the improbability of some legends which it does not actually disprove. Thus, when men believed the sun to be simply a lamp revolving around and lighting our world, they had no great difficulty in believing that it was one day literally arrested in its course, to illuminate an army which was engaged in massacring its enemies; but the case became different when it was perceived that the sun was the centre of a vast system of worlds, which a suspension of the earth’s motion must have reduced to chaos, without a miracle extending through it all. Thus, again, the old belief that some animals became for the first time carnivorous in consequence of the sin of Adam, appeared tolerably simple so long as this revolution was supposed to be only a change of habits or of tastes; but it became more difficult of belief when it was shown to involve a change of teeth; and the difficulty was, I suppose, still further aggravated when it was proved that, every animal having digestive organs specially adapted to its food, these also must have been changed. In the last place, physical science exercises a still wider influence by destroying what I have called the centre ideas out of which countless particular theories were evolved, of which they were the natural expression, and upon which their permanence depends. Proving that our world is not the centre of the universe, but is a simple planet, revolving with many others around a common sun; proving that the disturbances and sufferings of the world do not result from an event which occurred but 6,000 years ago; that long before that period the earth was dislocated by the most fearful convulsions; that countless generations of sentient animals, and also, as recent discoveries appear conclusively to show, of men, not only lived but died; proving, by an immense accumulation of evidence, that the notion of a universe governed by isolated acts of special intervention is untrue—physical science had given new directions to the currents of the imagination, supplied the judgment with new measures of probability, and thus affected the whole circle of our beliefs.
