Might this not come about from a wind in that quarter disturbing the waves at a distance? Sarsi seems to think that our intellect galilek be enslaved to that of some other man. This is quite a common figure of speech, as when one says: Guiducci, in the hope of doing something that would be welcome to men studious of truth, proposed with all modesty that henceforth it would be good to consider the nature of a comet, and whether it might be a mere appearance rather than a real object.

If he has, then how can he prefer to believe things related by other men as having happened two thousand years ago in Babylon assayre than present events which he himself experiences?

On the other hand almost equal disorder would ensue if the celestial orbs were of a solid substance and had surfaces not perfectly smooth, since then refractions would be disturbed and the movements, shapes, and projections of rays from the planets would be most confused and irregular. But poor as I tthe in courage and power, I am at least upright. It was useless to hold my peace, because those who are so anxious to make trouble for me have now had recourse assayef attributing to me the works of others.

That usually happens only with the words of great and celebrated men, which really far exceeds the bounds of my ambition. And even if the entire Discourse were the work of my pen hte – a thing that would never enter the mind of anyone who knows Guiducci-what kind of asayer is this for Sarsi to unmask me and reveal my face so zealously?

Well, now you have seen a great expenditure of words on the part of Sarsi and myself to determine whether the solid hollow of the lunar orb [15] which does not exist in Nature[p. He it was in Padua, where I resided at the time, who set forth assayet Latin the uses of my compass and had one of his pupils publish this and sign it.

After the theory was banned he utilized it to smuggle in the truth by pretending as here that Copernicus had spoken falsely in attributing a nonexistent motion to the earth. You see how this gave me what I sought; and such were the steps in my discovery, in which I was assisted not at all by the received opinion that the goal was a real one.

The translators of the King James version render this passage in an entirely different sense; namely, as “that which is wanting cannot be numbered. Meeting with our bodies, they penetrate by means of their extreme subtlety, and their touch as felt by us when they pass through our substance is the sensation we call “heat.

Well, if he succeeds I shall be the more obliged to him, as in the future I shall have one less theory to worry about when I set my mind to philosophizing on such matters. Frankfort,pp. External means capable of thus ruffling the air are very numerous, but for the most part they may be reduced to the trembling of some body which pushes the air and disturbs it. There I was often visited by friends. I believe that in the weaving of this cloth, Sarsi is going to get himself so entangled-far more than he supposes now, while he is laying the warp-that in the end he will voluntarily admit himself defeated.

Would you argue with him and maintain his proposition to be false? What I said was designed to remove a difficulty attributed to the Copernican system, and I later added that anyone who would reflect upon the matter more carefully would see that Copernicus had spoken falsely when he attributed his “third motion” to the earth, since this would not be a motion at all, but a kind of rest.

If you rub across this again, the ray will be led off in another direction. Next, you see, Sarsi represents me as being finally convinced by the force of his logic and snatching at some very slender straw by saying that if it is true the fixed stars fail to receive enlargement as do nearby objects, then at any rate this is because the same instrument is not used, as the telescope must be a longer one for very close objects. I say, moreover, that to discover the solution of a stated and fixed problem is a work of much greater ingenuity than to solve a problem which has not been thought of and defined, for luck may play a large part in the latter, while the former is entirely a work of reasoning.

Only too clearly does Sarsi show his desire to strip me aassayer of any praise. I am more like galildi monkey that firmly believed he saw another monkey in a mirror, and the image seemed so real and alive to him that he discovered his error only after runrung behind the glass several times to catch the other monkey.

But if you ever suggest this little game to Sarsi, and if he protests at great length, then I beg Your Excellency to tell him that I do not mean to imply by this that there is in the sky a huge carafe, and someone oiling it with his finger, thus forming a comet; I merely offer this as an example of Nature’s bounty and variety of methods for producing her effects.

Well, after this man had come to believe that no more ways of forming tones could possibly exist- after having observed, in addition to all gakilei things already mentioned, a variety of organs, trumpets, fifes, stringed instruments, and even that little tongue of iron which is placed between the teeth and which makes strange use asssayer the oral cavity for sounding box and of the breath for vehicle of soundwhen, I say, this man believed he had seen everything, he suddenly found assayfr once more plunged deeper into ignorance and bafflement than ever.

You, Sarsi, must show us that an interposed flame would not suffice to hide the stars.

The Assayer

I cannot help being astonished that Sarsi and his teacher, thinking it to be true, should have regarded it less highly than their others-which, if I may say so, are not fit to hold a candle to this one.

Lines are called regular when, having a fixed and definite description, they are susceptible of definition and of having their properties demonstrated. For my own part, never having read the pedigrees and patents of nobility of shapes, I do not know which of them are more and which are less noble, nor do I know their rank in perfection.

These leave some tracks in moving over the oily surface, and the reflection of fight takes place in their edges, and since they are numerous and assayeer arranged this forms a light stripe.

And why should I speak of the comet as shining like a planet?
