“[m]odern physics, therefore, reduces matter to a set of events which proceed outward from a centre”.
Since Russell states that the idea that radiation comes from lumps (or things) is unintelligible, then why is it any more intelligible to say that “events” (or radiation) “proceed outward from a centre” (163)? Is a physical center more intelligible than a lump (or a thing)? Despite saying that, Russell backs himself up by saying that “[i]f there is something further in the center itself, we cannot know about it”. Indeed such a thing is “irrelevant to physics”.
