I rely on Oppenheim and Putnam for a detailed exposition of the hypothesis that we may hope to find such a unified physicalistic body of scientific theory and for a presentation of evidence that the hypothesis is credible.
I have a couple questions concerning this last passage. First, it seems that we have to have one of two options. The first is to accept this view, with substantial credited backing, or, choose to believe that our natural sciences are greatly flawed and we have failed to account for this other stuff. Now, my question is, is there any evidence throughout history that this "other stuff" as ever existed? Or if there has ever been any evidence that suggests otherwise?
