We first introduce RBW, discuss its philosophical implications and provide an example of its explanatory methodology via the so-called "quantum liar experiment." We then provide a simple example of a quantum to classical transition in this context using a gedanken twin-slit experiment. We conclude by speculating on the extrapolation of RBW to quantum field theory, suggesting the need for a new principle of physics based in spatiotemporal relationalism. Accordingly, RBW suggests a novel approach to new physics which supplies a means for its falsification.40 pages of text, 16 figures. Submitted to Foundations of Physics.
