A short history of the origin and evolution of MBT. Thomas Campbell’s Theory of Everything is a model of reality that begins with two assumptions: Consciousness exists and Evolution exists; and from those two assumptions, provides a fully scientific explanation of both the objective and subjective worlds. It can derive both Relativity and Quantum Mechanics. The MBT model has also been successful at solving many outstanding paradoxes within several major fields of study. As far as the inner, subjective world, the MBT Model can help us understand our purpose here in Physical Matter Reality (PMR) and what we can do to find happiness in this life.
