Why do you ignore mathematical and logical truth? These would seem to fit what you describe quite well, with physics and the other sciences lagging somewhat behind.

We have found failures in Newton's laws of motion. We know that mass is not necessarily conserved now. We think mass-energy is conserved now. That is an accepted law and an accepted fact, scientifically speaking, but how do we know? We've been wrong before. Matter starts getting wacky at really small scales.

But the beauty of formal mathematics is that it has not been open to revision or dispute, in an important sense. (I use your word "open" loosely.) Yes, a few conjectures have proven wrong and there have been major earthshaking rumbles like Turing's proof about the stopping problem, Godel's incompleteness theorem, and so on.

But the fundamental axioms of mathematics and all the arithmetic, algebra, calculus, geometry, theorems, and proofs built upon them have held up infallibly through the ages. There have been conjectures that have proven wrong, there have been "proofs" that were found to be mistaken. But there has been no failure in mathematics. We haven't found a case where n*0 is not equal to 0. We haven't found a case where the whole is not equal to the sum of its parts. We haven't found a border in the Mandelbrot set where the detail is lost and it smooths out. We haven't found a triangle of more than 180 degrees.

Much of mathematics has been discovered independently by many ancient cultures. These advanced, beautiful theorems have held as true today as they did for cultures thousands of years ago.

This is one reason I love math. It is unreasonably effective. It is beautiful. It is, in a sense, indisputable.

As far as metaphysical, non-scientific, non-mathematical truth... well, what is it?
