I am suspicious then of scientific demonstrations in a question of concrete fact, in a discussion between fallible men. However, let those demonstrate who have the gift; “unusquisque in suo sensu abundet.” For me, it is more congenial to my own judgment to attempt to prove Christianity in the same informal way in which I can prove for certain that I have been born into this world, and that I shall die out of it. It is pleasant to my own feelings to follow a theological writer, such as Amort, who has dedicated to the great Pope, Benedict XIV., what he calls “a new, modest, and easy way of demonstrating the Catholic Religion.” In this work he adopts the argument merely of the _greater_ probability;(40) I prefer to rely on that of an _accumulation_ of various probabilities; but we both hold (that is, I hold with him), that from probabilities we may construct legitimate proof, sufficient for certitude. I follow him in holding, that, since a Good Providence watches over us, He blesses such means of argument as it has pleased Him to give us, in the nature of man and of the world, if we use them duly for those ends for which He has given them; and that, as in mathematics we are justified by the dictate of nature in withholding our assent from a conclusion of which we have not yet a strict logical demonstration, so by a like dictate we are not justified, in the case of concrete reasoning and especially of religious inquiry, in waiting till such logical demonstration is ours, but on the contrary are bound in conscience to seek truth and to look for certainty by modes of proof, which, when reduced to the shape of formal propositions, fail to satisfy the severe requisitions of science.(41)
