There will always be matters that are not empirically testable, as well as matters that are empirically testable. That doesn't worry me. You can only empirically test something if you have the necessary equipment (artificial or biological) with which to test it...and only if you know how to handle that equipment in an effective matter.

If I only believed in stuff that was empirically testable, I would have to become willfully blind to a great deal of what's out there...and my life would lose a large portion of what makes it most interesting for me.
