Non-absolutely. > As for microphysical causality, right, it doesn’t solve any > ontological problems to introduce it as an explanation because it just > raises the question “what causes microphysical causality?” It isn't an absolute explanation. It's still an explanation. BTW *you* introduced causality in order to deprecate reason and logic.

Yes I can: Occam;s razor.

Where is the mind? Pfft. If you switch your telly off, you don;t get a picture. Switch it on again, you do. That doesn't mean the picture is some additional immaterial thingumajig. > If you lightly smush my brain in a press, the brain is still there. > Is the mind still there? The brain is not there in a meaningful sense. You can't read a copy of War and Peace tat's been pulped. Obviously in these contexts "the brain" doesn't just mean so many electrons, protons, and neutrons, it means something material that has a certain structure and function. The atoms and molecules can be replaced over time, the structure and functions is vital > Assuming multiple realizability, if you run a simulation of me on a > computer, the mind is there. Where is the brain? If you have one, it is, under those circumstances, identical to the structural and functioning silicon substrate. Multiple realisability doesn't preclude token identity. > Mind-brain identity doesn’t seem so convincing to me.

Just don’t go pretending that they’re justified. Or just don'#t go arbitrarily assuming justfication has to be absolute. Put something on an infinitely tall pedestal and you can't reach it.
