Experience is a most logical and reasonable test if it is sufficiently extended to touch all the material phases of the subject under investigation. It is a most dangerous one if we insist upon judging the material and spiritual universe, with its infinite variety of forms and changes, by the limited experience of a simple and isolated life, or by the particular standards of any one age or race. A progressive civilization, under such an application of the test, would be impossible, since each generation of men would have to begin _de novo_, and be restricted to the results of its own experience. The enforcement of such a doctrine would prevent, furthermore, the acceptance of the truths of nature discovered by inventive genius or developed by physical or chemical research, until such truths had become matters of universal experience. Every man would then be in the position of the incredulous citizen who, having been told that a message had been sent by wire from Baltimore to Washington announcing the nomination of James K. Polk for the presidency, refused to believe in telegraphic messages until he could be at both ends of the line at once. The art of telegraphy was a reality, nevertheless, in spite of his incredulity and inexperience. The American savages who first beheld the ships of Columbus are said to have regarded them as huge birds from heaven and to have refused to believe that they were boats, because, in their experience, they had never seen such immense canoes with wings. Herodotus tells us of some daring sailors who crept along the coast of Africa beyond the limits usually visited at that time. They came back home with a wonderful account of their trip and told the story that they had actually reached a country where their shadows fell toward the south at midday. They were not believed, and their report was rejected with scorn and incredulity by the inhabitants of the Mediterranean coasts, because their only experience was that a man's shadow always pointed toward the north; and they did not believe it possible that shadows could be cast otherwise. But the report of the sailors was true, nevertheless.[27] These simple illustrations teach us that beings other than ourselves have had experiences which are not only different from any that we have ever had, but are also either temporarily or permanently beyond our comprehension. And the moral of this truth, when applied to the statements of the Evangelists regarding miracles, is that the fortunate subjects and witnesses of the miraculous powers of Jesus might have had experiences which we have never had and that we cannot now clearly comprehend.
