Proof...

Let’s examine the concept of “proof” with some specific, really difficult philosophical questions:

1. Define proof in your own words.
2. Is proof a variable (meaning “not consistent or having a fixed pattern”)?  If no, not a variable, why not? If yes, a variable, how so?
3. What kind of evidence does it take to prove something (categorical, circumstantial, quantitative, observable, repeatable, unfailing, a combination, etc.)?
4. How much evidence does it take to prove something? (50.0001%, 99%,100%)

Debate these questions among your fellow posters.
