Photons and Antiprotons.  Having already established that metaphysics over antimetachemistry at the northeast point of the intercardinal axial compass is equivalent to light over antiheat, I should now like to take the process a subatomic step further and contend, probably for the first time in my entire philosophical vocation, that light is equivalent to photons and antiheat to antiprotons, so that metaphysics becomes identified, willy-nilly, with photons and antimetachemistry with antiprotons.
