No man ought to say that seamen have neglected science. It is the fashion among some to talk of sailors as superstitious. They must know very little about sailors, and must be very blind to broad facts, who speak thus of them as a class. Many sailors, doubtless, are superstitious. But I appeal to every master mariner here, whether the superstitious men are generally the religious and godly men; whether it is not generally the most reckless and profligate men of the crew who are most afraid of sailing on a Friday, and who give way to other silly fancies which I shall not mention in this sacred place. And I appeal, too, to public experience, whether many, I may say most, of those to whom seamanship and sea-science owes most, have not been God-fearing Christian men? Be sure of this, that if seamen, as a class, had been superstitious, they would never have done for science what they have done. And what they have done, all the world knows. To seamen, and to men connected with the sea, what do we not owe, in geography, hydrography, meteorology, astronomy, natural history? At the present moment, the world owes them large improvements in dynamics, and in the new uses of steam and iron. It may be fairly said that the mariner has done more toward the knowledge of Nature than any other personage in the world, save the physician. For seamen have been forced, by the nature of their calling, to be scientific men. From the very earliest ages in which the first canoe put out to sea, the mariner has been educated by the most practical of all schoolmasters, namely, danger. He has carried his life in his hand day and night; he has had to battle with the most formidable and the most seemingly capricious of the brute powers of nature; with storms, with ice, with currents, with unknown rocks and shoals, with the vicissitudes of climate, and the terrible and seemingly miraculous diseases which change of climate engenders. He has had to fight Nature; and to conquer her, if he could, by understanding her; by observing facts, and by facing facts. He dared not, like a scholar in his study, indulge in theories and fancies about how things ought to be. He had to find out how they really were. He dared not say, According to my theory of the universe this current ought to run in such a direction; he had to find out which way it did actually run, according to God’s method of the universe, lest it should run him ashore. Everywhere, I say, and all day long, the seaman has to observe facts and to use facts, unless he intends to be drowned; and therefore, so far from being a superstitious man, who refuses to inquire into facts, but puts vain dreams in their stead, the sailor is for the most part a very scientific-minded man: observant, patient, accurate, truthful; conquering Nature, as the great saying is, because he obeys her.
