The conformity of testimony with experience is one of the most potent and universally applied tests of the credibility of witnesses. And it may be remarked that its application is not confined to judicial proceedings or to courts of law. It requires no professional attainments to make it effective. The blacksmith and carpenter, as well as the judge and jury, employ it in every mental operation where the statements of others are submitted to analysis and investigation. A new theory being proposed, the correctness of which is questioned, the test of experience is at once applied. If it is not in harmony with what we have seen and heard and felt, we usually reject it; or, at least, doubt it. If an explorer should return from the Arctic regions and tell us that he had seen oranges, such as we import from Florida, growing on trees near the North Pole, we would not believe him. Neither would we credit the statement of a traveler from South America that he had seen Polar bears browsing on the banks of the Amazon. These representations would be utterly inconsistent with what we know to be the essential conditions of orange culture, and with the well-known habits and climatic nature of the Polar bear. An ancient document, purporting to date from the time of Washington and the Revolution, and containing recitals about railways, telegraphs, telephones, and electric lights, would be recognized at once as spurious, because our own experience as well as facts of history would tell us that there were no such things in the days of Washington and the American Revolution. These are simple illustrations of the application of the test of experience in the mental processes of weighing and sifting the testimony of others. Now, no serious objection to the credibility of the Gospel writers has been made under the test of the conformity of their statements with experience, except in the matter of miracles. It is generally admitted, even by skeptics, that the facts stated in the New Testament narratives might have happened in the due course of nature and in harmony with human experience, except where miracles are related.
