5. Probability is either of sensible matter of fact, capable of human testimony, or of what is beyond the evidence
of our senses.
But to return to the grounds of assent, and the several degrees of it, we are to take notice, that the
propositions we receive upon inducements of probability are of two sorts: either concerning some particular
existence, or, as it is usually termed, matter of fact, which, falling under observation, is capable of human
testimony; or else concerning things, which, being beyond the discovery of our senses, are not capable of any
such testimony.
