Is it nothing but speculation?
My studies of the Analytics (including Russell) informed me of their idea that metaphysics is not worth spending time on, that philosophy should be treated with the same rigor as science.
It seems to me like the pre-socratics and other early metaphysicists were talking about supernatural and spiritual stuff that really gave me no better understanding of the world.
Are there fields of metaphysics that DO offer insight?
