The answers of the oracles were generally vague and indefinite, and susceptible of almost any interpretation, according to the result. Whenever the event corresponded with the prediction, or could be made to correspond with it by the ingenuity of the commentators, the story of the coincidence would, of course, be every where spread abroad, becoming more striking and more exact at each repetition. Where there was a failure, it would not be direct and absolute, on account of the vagueness and indefiniteness of the response, and there would therefore be no interest felt in hearing or in circulating the story. The cases, thus, which would tend to establish the truth of the oracle, would be universally known and remembered, while those of a contrary bearing would be speedily forgotten. There is no doubt, however, that in many cases the responses were given in collusion with the one who consulted the oracle, for the purpose of deceiving others. For example, let us suppose that Croesus wished to establish strongly the credibility of the Delphic oracle in the minds of his countrymen, in order to encourage them to enlist in his armies, and to engage in the enterprise which he was contemplating against Cyrus with resolution and confidence; it would have been easy for him to have let the priestess at Delphi know what he was doing on the day when he sent to inquire, and thus himself to have directed her answer. Then, when his messengers returned, he would appeal to the answer as proof of the reality of the inspiration which seemed to furnish it. Alexander the Great certainly did, in this way, act in collusion with the priests at the temple of Jupiter Ammon. * * * * * The fact that there have been so many and such successful cases of falsehood and imposture among mankind in respect to revelations from Heaven, is no indication, as some superficially suppose, that no revelation is true, but is, on the other hand, strong evidence to the contrary. The Author of human existence has given no instincts in vain; and the universal tendency of mankind to believe in the supernatural, to look into an unseen world, to seek, and to imagine that they find, revelations from Heaven, and to expect a continuance of existence after this earthly life is over, is the strongest possible natural evidence that there is an unseen world; that man may have true communications with it; that a personal deity reigns, who approves and disapproves of human conduct, and that there is a future state of being. In this point of view, the absurd oracles of Greece, and the universal credence which they obtained, constitute strong evidence that there is somewhere to be found inspiration and prophecy really divine.
