Of, or relatining to evidence accepted by empiricism. The fallacy of believing that nothing exists except what is proven by scientific evidence, of which there is no scientific evidence to prove; an arbitrary decision to to narrow the bounds of reality to the bounds of the scientific method.
"A trillion years ago we were a civilization like any other. We believed in the transmittance of souls, the Virgin matrix, the infallibility of Pi Squared, looked upon prayer as a regenerative feedback to the Great Programmer, and so on and so forth.
