Therefore, assume the resistance to credibility, in any preternatural occurrence, as equal to x, and the very ideal or possible value of human testimony as no more than x, in that case, under the most favorable circumstances conceivable, the argument for and against a miracle will be equal; or, expressing the human testimony by x, affected with the affirmative sign [+x]; and expressing the resistance to credibility on the other side of the equation, by x, affected with the negative sign [-x], the two values will, in algebraical language, destroy each other, and the result will be = 0. But, inasmuch as this expresses the value of human testimony in its highest or ideal form, a form which is never realized in experience, the true result will be different,--there will always be a negative result= [-y]; much or little according to the circumstances, but always enough to turn the balance _against_ believing a miracle. 'Or in other words,' said Hume, popularizing his argument, 'it will always be more credible that the reporter of a miracle should tell a falsehood, or should himself have been the dupe of appearances, than that a miracle should have actually occurred--that is, an infraction of those natural laws (any or all) which compose what we call experience. For, assume the utmost disinterestedness, veracity, and sound judgment in the witness, with the utmost advantage in the circumstances for giving full play to those qualities; even in such a case the value of affirmative testimony could, at the very utmost, be equal to the negative value on the other side the equation: and the result would be, to keep my faith suspended _in equilibrio_. But in any real case, ever likely to come before us, the result will be worse; for the affirmative testimony will be sure to fall in many ways below its ideal maximum; leaving, therefore, for the final result a considerable excess to the negative side of the equation.
