Where ever we have beliefs based on experience we can go as far as experience lets us go, but no further. This is Hume's idea of understanding. Again, if one points out the mathematical explanations, this does not hold. He says we cannot transcend experience, so we have no idea of immortality. We get all idea from experience.
Solid beliefs come from observing constant occurrences of something.
The only beliefs that will stand up are beliefs that give you strong imperial evidence. Skepticism leads to moderation in views and that is good. The changing of these views leads us to still show that Hume is wrong in that faith, infinite, and God still exists in human minds, even though we have never experienced him fully. As shown, time did not always have miracles on text to show them the way. We had faith and hope, and for many that is still all they have or need.
