I don't know if they will become scientific or not. I wasn't trying to speculate about the future, just to point out that there are lots of things that people know but can't prove in a scientific sense. As a matter of fact, there is an interesting book about it: [What We Believe but Cannot Prove](http://en.wikipedia.org/wiki/What_We_Believe_But_Cannot_Prove http://en.wikipedia.org/wiki/What_We_Believe_But_Cannot_Prov...). Just off the top of my head, I'd say the most obvious thing that people know that isn't scientific is to make creative leaps and discover/invent new ideas. Science can tell us a lot about how it happens, but there is no scientific formula for creating new, true, useful, or provocative ideas. When people make a creative leap, do they know it's true, in the scientific sense? Or how about humor? Can you scientifically prove a joke to be funny? I know what I find funny, but humor is not provable, or created following the scientific method.
