Absolutely

We cannot predict, absolutely, that matter's of fact as defined by Hume are a matter of cause and effect. This is true because cause and effect, in itself, is a matter of probability, not certainty. In other words; I am pretty sure that the sun will rise tomorrow. I am not 'absolutely certain' that it will though. How do I know? What if it doesn't? In a more realistic example, we could point out how this argument could be in err. One example would be to relate the effect of something to the wrong cause. How certain are we that the cause we identify is the real source of the effect? Since all we can experience is the effect from which to look for a cause, how do we know for certain the real cause? Therefore, we cannot know absolutely the cause of an effect.
