Yet Popper asserts that "There exist natural laws" is true, and its truth can be argued for. He defends this assertion as part of what he calls "metaphysical realism". And then I suppose he would also hold that there are other metaphysical -isms that CAN be falsified? (Metaphysical Idealism, say) -- or IS indeed falsified. I would not think so, since that may lead to an inconsistency. For we may be having Popper defending a preference for some metaphysical -ism, which, unlike metaphysical realism, IS 'falsifiable'?
