FORE:In arranging the details of machines, it is impossible to have a special standard of dimensions for each case, or even for each shop; the dimensions employed are therefore made to conform to some general standard, which by custom becomes known and familiar to workmen and to a country, or as we may now say to all countries.
FORE:By cutting up some of the longer essays into parts, Porphyry succeeded, much to his delight, in bringing the whole number up to fifty-four, which is a product of the two perfect numbers six and nine. He then divided them into six volumes, each containing nine booksthe famous Enneads of Plotinus. His principle of arrangement was to bring together the books in which similar subjects were discussed, placing the easier disquisitions first. This disposition has been adhered to by subsequent editors, with the single exception of Kirchhoff, who has printed the works of Plotinus according to the order in which they were written.418 Porphyrys scrupulous information has saved modern scholars an incalculable amount of trouble, but has not, apparently, earned all the gratitude it deserved, to judge by Zellers intimation that the chronological order of the separate pieces cannot even now be precisely determined.419 Unfortunately, what could have been of priceless value in the case of Plato and Aristotle, is of comparatively small value in the case of Plotinus. His280 system must have been fully formed when he began to write, and the dates in our possession give no clue to the manner in which its leading principles were evolved.420
FORE:"The guns are horrid, madame; are you not afraid?"Kicking rudder and dipping a wing, almost wetting it in the spray of a breaking comber, he flung his airplane into a new line of flight, reversed controls, giving opposite rudder and aileron, got his craft on a stable keel and gave it the gun as he snapped up the flippers to lift her nose and climb after the retreating plane.
FORE:Let it be remembered that the gods of whom Plato is speaking are the sun, moon, and stars; that the atheists whom he denounces only taught what we have long known to be true, which is that those luminaries are no more divine, no more animated, no more capable of accepting our sacrifices or responding to our cries than is the earth on which we tread; and that he attempts to prove the contrary by arguments which, even if they were not inconsistent with all that we know about mechanics, would still be utterly inadequate to the purpose for which they are employed.
