And of dangers in general this we may say—that if we pray against known dangers which we can avoid, we do nothing but tempt God: but that against unknown and unseen dangers we may always pray. For instance, if a sailor needlessly lodges over a foul, tideless harbour, or sleeps in a tropical mangrove swamp, he has no right to pray against cholera and fever; for he has done his best to give himself cholera and fever, and has thereby tempted God. But if he goes into a new land, of whose climate, diseases, dangers, he is utterly ignorant, then he has surely a right to pray God to deliver him from those dangers; and if not,—if he is doomed to suffer from them,—to pray God that he may discover and understand the new dangers of that new land, in order to warn future travellers against them, and so make his private suffering a benefit to mankind. This, then, is our duty as to known dangers,—to guard ourselves against them by science, and the reason which God has given us; and as to unknown dangers, to pray to God to deliver us from them, if it seem good to him: but above all, to pray to him to deliver us from them in the best way, the surest way, the most lasting way, the way in which we may not only preserve ourselves, but our fellow-men and generations yet unborn; namely, by giving us wisdom and understanding to discover the dangers, to comprehend them, and to conquer them, by reason and by science. This is the spirit of sound science and of sound religion. And it was in this spirit, and for this very end, that this Ancient and Honourable Corporation of the Trinity House was founded more than three hundred years ago. Not merely to pray to God and to the saints, after the ancient fashion, to deliver all poor mariners from dangers of the seas. That was a natural prayer, and a pious one, as far as it went: but it did not go far enough. For, as a fact, God did not always answer it: he did not always see fit to deliver those who called upon him. Gallant ships went down with all their crews. It was plain that God would not always deliver poor mariners, even though they cried to him in their distress. Then, in the sixteenth century, when men’s minds were freed from many old superstitions, by a better understanding both of Holy Scripture and of the laws of nature, the master mariners of England took a wiser course.
