What the Latins have

What the Latins have done in this text (1 John v, 7) the Greeks have done to Paul (1 Tim. iii, 16). They now read, Great is the mystery of godliness; God manifest in the flesh; whereas all the churches for the first four or five hundred years, and the authors of all the ancient versions, Jerome as well as the rest, read, Great is the mystery of godliness, which was manifest in the flesh. Our English version makes it yet a little stronger. It reads, Great is the mystery of godliness: God was manifest in the flesh.
Isaac Newton

There will certainly be

There will certainly be no lack of human pioneers when we have mastered the art of flight….Let us create vessels and sails justed to the heavenly ether, and there will be plenty of people unafraid of the empty wastes. In the meantime we shall prepare, for the brave sky-travelers, maps of the celestial bodies.
Johannes Kepler
