Actually in the brilliance of the brightest flashes of lightning not the slightest movement or change of shape is discerned in the clouds, and this is just when thunder is being formed. But from which of those sources the two authors mentioned by Sarsi derive the scarcity of their followers I do not know, for I have not studied their works sufficiently to judge .
Well, now you have seen a great expenditure of words on the part of Sarsi and myself to gqlilei whether the solid hollow of the lunar orb  which does not exist in Nature[p. First you try to place me under great obligations by galjlei new virtues upon this supposed child of mine, and next you ten me it is only an adopted one.

Would you glilei with him and maintain his proposition to be false? If Sarsi and others think that certainty of a conclusion extends much assistance in the discovery of some means for realizing it, let them study history. Instead of placing the fire as far away as a comet, I am satisfied with a distance of one hundred yards.

On the other band magnificent titles and many grandiose promises attract the natural curiosity of men and hold them forever involved in fallacies and chimeras, without ever offering them one single sample of that sharpness of true proof hhe which the taste may be awakened to know how insipid is the ordinary fare of philosophy. When Sarsi heated his bit of copper by pounding it many times, I can well believe that he detected no diminution in its galulei even by the most delicate balance.

The charge of plagiarism from Galileo’s books could not be aimed at Scheiner himself for obvious reasons, but judging from the bitter attack on Galileo in the Rosa Ursina and from its author’s undoubted role in Galileo’s final condemnation, Scheiner believed that to be the intention.
I reply that if those poets could be present at our experiments they would change their views, and without disgrace they could say they had been writing hyperbolically-or even admit they had been wrong.
External means capable of thus ruffling the air are very numerous, but for the most part they ga,ilei be reduced to the trembling of some body which pushes the air and disturbs it. That is a very true statement, even though Sarsi appears to disbelieve it and acts as if acquainted with neither nature nor poetry.
This will become apparent to anyone [p. He attached no less importance to reason assyer to experiment, and he had no doubt about the independent truth of mathematical propositions, the denial of which has always involved empiricist philosophers in serious difficulty with the best logicians.
I shall be content to have you shoot an arrow not with a simple longbow, but teh the stoutest steel crossbow, or use a catapult drawn by lovers and windlasses that could not be managed by thirty of your ancient heroes. And who knows; perhaps in Sarsi’s eyes the pettiness of the theft does not render me more blameworthy than I would be if I had bravely applied myself to greater [p. A visit to Rome confirmed this.
