I’ve been thinking lately how difficult it is to know something for certain.  How can I be sure that what I know to be true is indeed true?

I have a lot of doubts.  There are many things I’m quite uncertain about; too uncertain to make a judgment as to their truth or falsity.

And there are quite a few things I have opinions about; things I judge to be so with a pretty high degree of certainty but am not absolutely sure to be the case.

Then, there are things I’m sure are true because they behave or exist in a manner consistent with what my mind expects them to do or be.

But can I be sure these things I’m sure are true are absolutely true?  Are they true for everyone all the time for ever and ever?  And if these sure things aren’t true for everyone all the time for ever and ever how can I be sure of their truth?

Well, it’s a true enigma; how can I know that I know what I know, that’s what I’d like to know.
