Dion Fortune noted that the Metaphysical must retreat as the physical sciences developed because new and better answeres justified that. But I think any disapline can become self limeting. For example: the idea of circular equations is not popular in the physical sciences but I read where determeaning rather time goes foward or backwards was indeterminate. We cant prove it either way. We cant even measure a lot of things without alturing them. So what is wrong with a linear universe? We use that to build many fine bridges and they serve us well. But we cant find a beginning or end of time any more then we can put a fence on where the universe begins and ends. Logic dictates it must curve upon itself in ways we can't understand. So I think the occult - the hidden - isnt necessarily destroyed by cold math and science or rendered obsolete. It is just that certain concepts are outside the classroom mentality such as anything with no beginning and no end. Our maths fail us in explaining that and that is exactly why metaphysics leads the way untill science catches up with it ....
