1714: Gottfried Wilhelm von Leibniz, who discovered the differential and integral calculus, said that below the material universe there is a metaphysical reality that serves as its base and generates it. Space and time, mass and movement in physics and transference of energies are intellectual constructs, that is, inventions of thought.
1902: William James proposed that the brain normally filters a greater reality.
