Probability is the appearance of the agreement or disagreement of two ideas by the intervention of proofs whose connection is not constant, but appears for the most part to be so.
The mind ought to examine all the grounds of probability, and, upon a due balancing the whole, reject or receive it proportionably to the preponderancy of the greater grounds of probability on the one side or the other.
Though moral certainty be sometimes taken for a high degree of probability, which can only produce a doubtful assent, yet it is also frequently used for a firm assent to a thing upon such grounds as fully satisfy a prudent man.
