 Several of the most widely-discussed arguments aimed at establishing that there is no legitimate place for causal notions in physics can be traced to the writings of Ernst Mach (1900, 1905) and to Bertrand Russell’s extremely influential article “On the Notion of Cause” (1912). Russell’s target is the notion of cause in general, even though some of his arguments appeal to purported features of physical theorizing. Mach’s arguments focus more directly on physics, arguing that there is something distinct about physics that makes it especially inhospitable to causal notions. Contemporary defenders of neo-Machian and neo-Russellian arguments include Huw Price (1997; Price &amp; Weslake 2009), Hartry Field (2003), John Earman (2011), and, to some extent, John Norton (2003; 2007;  2009).[3]
