Truth and understanding are not such wares as to be monopolized and traded in by tickets and statutes and standards. We must not think to make a staple commodity of all the knowledge in the land, to mark and license it like our broadcloth and our woolpacks.
John MiltonHow soon hath Time, the subtle thief of youth, stolen on his wing my three-and-twentieth year!
John MiltonFrom Man or Angel the great Architect Did wisely to conceal, and not divulge, His secrets, to be scanned by them who ought Rather admire. Or, if they list to try Conjecture, he his fabric of the Heavens Hath left to their disputes - perhaps to move His laughter at their quaint opinions wide Hereafter, when they come to model Heaven And calculate the stars: how they will wield The mighty frame: how build, unbuild, contrive To save appearances; how gird the Sphere With Centric and Eccentric scribbled o'er, Cycle and Epicycle, Orb in Orb.
