My reasoning was this. Thus Sarsi may see that insensible reductions of weight do occur from consumption over a period of months on end, let alone the few minutes he may have persisted in hammering away at his bit of copper.

But poor as I am in courage and power, I am at least upright. The primary qualities exist regardless of people, but the secondary qualities would disappear without living creatures to experience them—secondary qualities exist only in the experiencing body. I had written of making my first observation on the seventh of January, 16io. I replied to them that I had only some questions to raise, which I was unable to write down because of my infirmity, but that I hoped these ideas of mine would soon be included in a discourse by a friend who had taken the trouble to collect them.

To adduce more witnesses serves no purpose, Sarsi, for we have never denied that such things have been written and believed. Sarsi says he has it from my Starry Messenger that the fixed stars are widely irradiated with a fulgor which is not real but only apparent, as they shine with their own light; that the planets, having no light of their own, are not similarly irradiated- especially the moon, Jupiter, and Saturn, which are seen to be almost devoid of any such splendor; and that Venus, Mercury, and Mars, though they have no light of their own, are nevertheless irradiated by reason of their proximity to the sun and their consequent bright illumination by it.

Let us therefore go no further than our original intention, which was to set forth the questions that appeared to upset the old- theories, and to propose a few new ideas.

He attached no less importance to reason than 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.

Philosophy is written in this grand book, the universe, which stands continually open to our [p. The rubbing together and friction of two hard bodies, either by resolving their parts into very subtle flying particles or by opening an exit for the tiny fire-corpuscles within, ultimately sets these in motion; and when they meet our bodies and penetrate them, our conscious mind feels those pleasant or unpleasant sensations which we have named heat, burning, and scalding.

Here She Be — The Battlements. Yet if true philosophers are like eagles they are not [unique] like the phoenix. The strings of a harp are all of the same material, but they produce different sounds because they are of various lengths. We merely do not believe that a cold arrow shot from a bow can take fire in the air; rather, we think that ff an arrow were shot when afire, it would cool down more quickly than it would if it were held still. Grassi had referred to the views which Kepler ler had set forth in an early optical work, and Galileo rightfully objected to the implication that these views were similar to his own.

Comets may be dissolved in a few days, and they are not of a circular and bounded shape, but confused and indistinct-indicating that their material is thinner and more tenuous than fog or smoke.

Sarsi wishes to persuade me that the fixed stars receive no appreciable enlargement from the telescope. But on the other hand one may make now a larger and now a smaller tube with the same quantity of material, say the same five pounds galile lead, and form different notes from it.

Well, I lack the stomach for this and I freely confess this cowardice. This gaoileo rotation, opposite in direction to all other celestial motions, appeared to many a most improbable thing, and one that upset the whole Copernican system.

Yet finding himself now to have two unanticipated ways of producing notes and melodies, he began to perceive that still others might exist. Now maybe I can actually check twitter occasionally. Now for this reason, forced to act by this unexpected sasayer uncalled-for treatment, I break my gqlileo resolve gwlileo publish no more. If their opinions and their voices have the power of calling into existence the things they name, then I beg them to do me the favor of naming a lot of old hardware I have about my house, -gold.

Instantly you will see a ray formed in imitation of the tail of a comet, cutting right across the place where you rubbed your finger. Of bodies that are rubbed together, some are certainly not consumed, others are quite perceptibly consumed, and still others are indeed consumed, but insensibly.

What I say is not entirely improbable, or merely a refuge which will leave the adversary some trouble in refuting it. 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.

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.

Or, if gallleo do not succeed, at least they will derive some benefit in the form of a clarification of their ideas about the help which they expect from a foreknowledge of the assayed.

Hence I think that tastes, odors, colors, and so on are no more than mere names so far as the object in which we place them is concerned, and that they reside only in he consciousness.

It is as if the premises had been prepared not by the bounty of nature but by the precision of the subtlest art.

Galileo states that vision relates to light, but in a complicated way that he does not understand much about and even to explain what he does know would take too long, so he does not assayet further into this observation.

The invention is, of course, contested in favor of several other men about this time. Sarsi would fail to remove these objections no matter bow many new proofs of his own he added, even if they were themselves conclusive.

It is certainly true that to the person holding the bowl such a ball appears to move with respect to himself and to the bowl, and to turn upon its axis.

As to his question why the moon is not smooth, I reply that it and all the other planets are inherently dark and shine by light from the sun. That is a very true statement, even though Sarsi appears to disbelieve it and acts as if acquainted with neither nature nor poetry.

Or take a ball of musk and carry it with you for a fortnight; it will assayee with odor a thousand rooms and streets which cannot happen without some diminution of mate rial; yet you will find none by weighing it. Things do not need to heat up simply because they are moving.

For an answer to this let him put down whatever it is that he would reply to a man who argued that the surface of the ocean should be bony and scaly, since the fish which inhabit it are.
