Shadows of the Mind. "Understanding is, after all, what science is all about – and science is a great deal more than mere mindless computation."^1a PLATO ARISTOTLE DESCARTES PASCAL BERKELEY VOLTAIRE JAMES SANTAYANA RUSSELL POPPER ORWELL DRUCKER

" . . . the ‘tilting’ of light cones, i.e. the distortion of causality due to gravity, is not only a subtle phenomenon, but a real phenomenon, and it cannot be explained away by a residual or ‘emergent’ property that arises when conglomerations of matter get large enough."^1b*

" . . . [Einstein’s general relativity] theory is confirmed overall to an error of no more than about 10^-14."^1c EINSTEIN WIGNER

"The expectations of quantum theory were triumphantly vindicated . . ."^1d PLANCK SCHRODINGER

"Gödel’s argument does not argue in favour of there being inaccessible mathematical truths. What it does argue for, on the other hand, is that human insight lies beyond formal argument and beyond computable procedures. Moreover, it argues powerfully for the very existence of the Platonic mathematical world. Mathematical truth is not determined arbitrarily by the rules of some ‘man-made’ formal system, but has an absolute nature, and lies beyond any such system of specifiable rules."^1e* PLATO WIGNER
