“Ontological Fourier mathematics is the complete mathematical explanation of Cartesian philosophy. It converts a substance dualism into a dual-aspect substance monism. There is only one substance - mathematics - but it can exist both dimensionlessly (as mind) and dimensionally (as matter, the product of mind). Mind adds the framing dimensions of space (extended real numbers) and time (extended imaginary numbers) to the unextended real and imaginary numbers of the frequency domain. (Ontologically, frequencies are not in space and time. They are instead the source of space and time).”
