Nay Nay what we have here is but One Yay.

How to explain that which goes without saying, that which is self-evident or what which is proof upon itself? Is it not absurd this erroneous notion in contemporary science, which grew out of unknowingness, out of forgetfulness, to demand evidence or empirical proof when there is only the empirical? Nay nay what we have here is but One Yay. There is only the empirical. All this is but the one heavenly winged abode!
