Now the improbability which arises from the want (for this properly is a want, not a contradiction) of experience, is only equal to the probability there is, that, if the thing were true, we should experience things similar to it, or that such things would be generally experienced. Suppose it then to be true that miracles were wrought on the first promulgation of Christianity, when nothing but miracles could decide its authority, is it certain that such miracles would be repeated so often, and in so many places, as to become objects of general experience? Is it a probability approaching to certainty? Is it a probability of any great strength or force? Is it such as no evidence can encounter? And yet this probability is the exact converse, and therefore the exact measure, of the improbability which arises from the want of experience, and which Mr. Hume represents as invincible by human testimony.
It is not like alleging a new law of nature, or a new experiment in natural philosophy; because, when these are related, it is expected that, under the same circumstances, the same effect will follow universally; and in proportion as this expectation is justly entertained, the want of a corresponding experience negatives the history. But to expect concerning a miracle, that it should succeed upon a repetition, is to expect that which would make it cease to be a miracle, which is contrary to its nature as such, and would totally destroy the use and purpose for which it was wrought.
The force of experience as an objection to miracles is founded in the presumption, either that the course of nature is invariable, or that, if it be ever varied, variations will be frequent and general. Has the necessity of this alternative been demonstrated? Permit us to call the course of nature the agency of an intelligent Being, and is there any good reason for judging this state of the case to be probable? Ought we not rather to expect that such a Being, on occasions of peculiar importance, may interrupt the order which he had appointed, yet, that such occasions should return seldom; that these interruptions consequently should be confined to the experience of a few; that the want of it, therefore, in many, should be matter neither of surprise nor objection?
