    We propose a path integral over graphs approach to quantum gravity and unification that requires a modification and reinterpretation of both general relativity and quantum field theory via their graphical instantiations, Regge calculus and lattice gauge theory, respectively. As we outline below, the spacetime metric and the matter and gauge field gradients on the graph are co-determining, so there is no “background spacetime” connoting existence independent of matter-energy-momentum, and the gra…Read more

    We propose a new path integral based interpretation of quantum field theory. In our interpretation, QFT is the continuous approximation of a more fundamental, discrete graph theory whereby the transition amplitude Z is not viewed as a sum over all paths in configuration space, but measures the symmetry of the differential operator and source vector of the discrete graphical action. We propose that the differential operator and source vector of theory X are related via a self-consistency criterio…Read more

    Dissertation, The University of Oklahoma. 1994.
    Nonreductive physicalism is the conjunction of the following three statements. Firstly, mental properties are real. Secondly, mental properties are neither reducible to nor identifiable with physical properties, and thirdly, mental properties are causally efficacious with respect to physical properties. Nonreductive physicalists hold these assumptions to be true not only for mental properties but all special science and macrophysical properties. I will defend the following three theses: first, i…Read more
