“In all human transactions, the highest degree of assurance to which we can arrive, short of the evidence of our own senses, is that of probability. The most that can be asserted is, that the narrative is more likely to be true than false; and it may be in the highest degree more likely, but still be short of absolute mathematical certainty. Yet this very probability may be so great as to satisfy the mind of the most cautious, and enforce the assent of the most reluctant and unbelieving. If it is such as usually satisfies reasonable men, in matters of ordinary transaction, it is all which the greatest sceptic has a right to require; for it is by such evidence alone that our rights are determined, in the civil tribunals; and on no other evidence do they proceed, even in capital cases.”
