I was wondering what fact was. I came to the realization that people rely on their senses. But those can never be proven to be factual. But people rely on them. Why? Because it makes sense.
Thus, the general definition of fact, it that which makes sense. But makes sense to one person may not to another. So, it would have to be a universally agreed upon opinion. But, that's nearly impossible. So, it would have to be the plausible to the majority of people. But fact is many times not plausible to anyone (even if they believe it to be true). So, that leads to
The problem is, that is not what people believe fact to mean. So, (IIRC) one day I was driving, I saw my younger brother, I rolled down the window and asked him, "what is fact?" He replied, "that which is". *Poof* I was enlightened.
So, fact is what is. But, noone can *prove* that what they believe to be fact is acutally fact. The proof for that is that many people believe incorrect things. And if you'll say, "they're in the minority", I'll reply, "so the majority defines that which is?"
That leads to two forms of fact. Actual Fact, or that which (actually) is. And Believed Fact, or that which is believed to be fact. (Until now I personally, have been using the terms "Real Truth" and "Human Truth", but I am open on that.)
Actual Fact can be known, but people don't know that it is known. Unless "know" is in quotes, but that is belief anyway.
Believed Fact is per person. And Believed Fact may also be Actual Fact, but that cannot be known.
