Or at least, we do not positively disagree.<br /><br />Said u: My point was that the very idea that a force is imparted to a projectile and this causes motion, rather than Aristotle's antiperistasis, is not Newton's but was long ago discovered by Philoponus, but Newton does not acknowledge so great a source for so fundamental an idea.<br /><br />Say I: a) Newton may well have discovered it independently, it may even have occurred to Aristotle but if so he may have refuted it as a consequence of his concept that matter is inert (=contains no cause of movement rather than Newton's =contains no cause for changing its movement or nonmovement). b) Newton already nearly said he did not bother to cite old sources since they did nothing as systematically close to Mathematics as he, which accounts for not citing either Philoponus or Buridan without actual denuial of them having discovered part of it before c) Newton was not under modern copyright legislation d) Newton's statement - as you agreed above - significantly and reletivistically differs from earlier statements<br /><br />Said you: The result has been that men now speak of Newtonian physics and motion when they should speak of Philoponussian physics and motion.<br /><br /><br />Say I: do you talk of Neperian or of Bradwardinian logarithms? Bradwardine - a scholastic who denied free-will and real presence (but notv papacy or episcopacy) - had the idea of correspondence between arithmetic and geometric progressions, which is at the root of Neper's logarithms. But it was Neper who worked out the useful tables. Likewise, Newton made a system encompassing much detail, and useful for reference. Not all of it is based on either his misstatement of Buridan or on his partial correctitude in restating Buridan, whether he had read him or not.<br /><br />Re Einstein, I enjoyed your posts on his mistakes enough to link to your posts.<br /><br /><a href="http://filolohika.blogspot.com/2009/12/astrology-may-well-be-astrolatry-but.html" rel="nofollow">Here is my post, link to the ones you write are in comments field</a>Hans Georg Lundahlhttps://www.blogger.com/profile/01055583255516264955noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-16858826211800321212010-01-11T15:21:35.049+00:002010-01-11T15:21:35.049+00:00Dividing answer into personal (this one) and scien...Dividing answer into personal (this one) and scientific (the other one, whichever you authorise first).<br /><br />Said I: No, it is not at all Marchia who had trodden the slippery slope of Newton. <br /><br />Said you: As I say, I never said he did.<br /><br />You are attacking a straw man and putting words in my mouth.<br /><br />Say I: I did not say you said he did, but that you said that I said that he did, thereby putting words in my mouth.<br /><br />Said u: And I think you are not reading my replies.<br /><br />Say I: Not all of them, but at least what I reply to.

Perhaps you are an officer, after all?<br /><br />As to the remainder, I am afraid I must repeat: I do not consider his law identical to what Marchia said, and I never said so.<br /><br />I maintain that Newton copied Buridan and Philoponus without acknowledging them and pretended that he had invented the idea, and not they, that Aristotle's physics was wrong and that impetus more accurately represented the truth.<br /><br />Neither did I ever say (despite your slight obsession with the subject) that "Newton's seeing uniform motion as no sign of a presently active prime mover is tantamount to saying Marchia did not see it so".<br /><br />What I said was that you pretended that I asserted: "that Marchia believed that stillness means there is no Divine first mover."<br /><br />Neither did I say that intellectual property is more important than getting a principle right.<br /><br />You are up to your old tricks in putting words in my mouth.<br /><br />You may reserve whatever rights you wish but not on my blog.<br /><br />I agree with you about Mahomet and the ridiculous Buccaille.<br /><br />You are free to find it equally ridiculous to assert that Marchia had already trodden the slippery slope of Newton - equating uniform motion with stillness in causality - leading to Einstein who equated them in physical geometry as well.<br /><br />But that is not, of course, what I said.<br /><br />You put words in my mouth again.<br /><br />But if you read my other posts you will find that I also agree with you that there are serious errors in Einstein's theories.<br /><br />You then merely repeat yourself - like a cracked record - in introducing (again) intellectual property which is irrelevant.Tribunushttps://www.blogger.com/profile/17330137792269530812noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-56247771372147626292010-01-09T09:39:52.704+00:002010-01-09T09:39:52.704+00:00I do however admit to not having read further than...I do however admit to not having read further than first pages after preface.<br /><br /><i>Newton certainly does cite other sources e.g. in the Preface he mentions Pappus and Halley, in Book I, p.316 he cites Grimaldus, in Book 1. p.318, he cites Cartesius and these are just a few which I readily found.

The sources he does cite according to your words indicate however that he does so of courtesy to living, or maybe also recently living scholars, that is men whose reputation was yet to be made or unmade.<br /><br />And I repeat: even if you do consider his law identical to what Marchia said, I do not. Even if you think saying Newton saw uniform motion as no sign of a presently active prime mover is tantamount to saying Marchia did not see it so, I do not. Even if you think intellectual property more important than getting a principle right, I think it more important to get a principle right. And I reserve me the right to speak or write according to my priorities, even if it is brought about by material on your post.<br /><br />Buccaille (Maurice) was a French doctor who enjoyed lots of hospitalities on an oriental journey, and having finished it wrote abook asserting that a) the Christian Bible contains assertions conflicting with Science, b) the Quran does not, but contains material scientifically inaccessible in Mohammed's time, and yet correct. Part of his theoreme is based on fact that Quran is less specific in opposition to heliocentrism than Joshua and Psalms, part that the words "and he set a fixed orbit for sun and moon" refer to their recently discovered rotations on own axes rather than their annual and mensual orbits around zodiak. And part on the fact that he discovered Pharao's army using Quran, and hiding fact that this had already been done by someone using Exodus. THAT is a context where I find plagiarism a real menace to intellectual <i>honesty.</i> And I find it ridiculous to want to hide that Mohammed was a geocentric, like any sane man else in his time, and I find it equally ridiculous to assert that Marchia had already trodden the slippery slope of Newton - equating uniform motion with stillness in causality - leading to Einstein who equated them in physical geometry as well.<br /><br />The claim Newton had read Marchia or anyone else saying same thing implies not only "plagiarism" but also either lack of understanding or deliberate "going beyond" into some seed of Einsteinism.<br /><br />But intellectual <i>property</i> - as opposed to the honesty that is always binding - was neither morally nor legally binding in Newton's time (confer fact that US and UK have separated since and have different copyright legislations due to laws having been made after that separation - and in France the right to pose a patent for an invention was not voted until 1793 or 98.Hans Georg Lundahlhttps://www.blogger.com/profile/01055583255516264955noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-46861352931372963942010-01-08T21:32:22.867+00:002010-01-08T21:32:22.867+00:00Responding to your next outburst.

There are many more.<br /><br />In his preface he writes:<br /><br />"<i>For I am induced by many seasons to suspect that they may all depend upon certain forces by which the particles of bodies, by some causes hitherto unknown, are either mutually impelled towards each other and cohere in regular figures, or are repelled and recede from each other; which forces being unknown, Philosophers have hitherto attempted the search of Nature in vain. But I hope the principles here laid down will afford some light either to that, or some truer, method of Philosophy.</i>"<br /><br />It is frankly absurd to suggest that Newton was somehow no more than compiling a collection of maxims and theorems that were already well established and was not claiming to have made discoveries. Of course he was claiming so, just as he claimed with calculus.<br /><br />And it is patently clear that he goes far further than mere insinuation<br /><br />You thereafter again try to put words in my mouth.<br /><br />I did not assert your objection.<br /><br />What I said was that Newton stole his idea from previous scholars.<br /><br />He did so without citing his source.<br /><br />That is not the same as the straw objection which you put up.<br /><br />You then return to your claim about sermons as a dog returns to its vomit, even though the point has now been answered no less than 3 times.<br /><br />You then go on - yet again! - to pretend that I was challenging your view of the <i>prima via</i> when I did not mention it. It was you who raised it, not me.<br /><br />Finally, you pretend - with a degree of sbsurdity which is fast becoming your chief characteristic in this disucssion - an assertion that Marchia believed that stillness means there is no Divine first mover when no such assertion has ever been made by anyone in this exchange and only you have raised it.<br /><br />Putting words in the mouth of another is not remotely at the top of intellectual distinction.

I think he was a plagiariser, a cheat and not a very nice man.<br /><br />I am perfectly well disposed to hear any reasoned argument or evidence that shows he was wrong scientifically.<br /><br />But you have not - as yet - advanced any.<br /><br />You have merely asserted and - which is sillier - tried to put words in my mouth which I did not say.Tribunushttps://www.blogger.com/profile/17330137792269530812noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-2682412421231699602010-01-08T16:43:05.613+00:002010-01-08T16:43:05.613+00:00Logic:

Marchia likened the law of impetus to the Blessed Sacrament saying that grace entered the soul through the Sacrament but was lost by sin, just as impetus was imparted to an object causing movement until an opposite force, like sin, stopped the movement.</i><br /><br />Entirely consistent with my view of Prima Via: movement, even uniform, is something <i>imparted on matter</i>, ultimately by God who is first mover. It is, even uniform, opposed to stillness or inertia.<br /><br />To Newton, by contrast, uniform motion is just another variety of inertia/stillness. That is: no sign of any mover. Divine or secondary.<br /><br />Saying this is same thing as stated previously by Francesco di Marchia is not quite at the top of intellectual distinction.Hans Georg Lundahlhttps://www.blogger.com/profile/01055583255516264955noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-14878395435978377072010-01-08T13:20:27.851+00:002010-01-08T13:20:27.851+00:00No, I still think you are wrong.

Hitting thin air and kicking in open doors is honourable to you?<br /><br />I agree Newtons first law is a major point in Newton. I agree if he cited sources for minor things he should also have cited sources for this one.<br /><br />BUT he did not pretend to cite his sources.<br /><br />THEREFORE he did not pretend to have invented this or that point which he cited no source for.<br /><br />I think indeed Newtons first law is so much a major point in Newton that it is a major point whether he got it right or wrong and relative to that a very minor point where he got it from.<br /><br />I think he got it wrong. I think his version of it conflicts with Prima Via in the five ways of proving God's existence. I think it modifies it sufficiently to make deism an intellectual option, which is bad. I hope Philoponus and Buridan did not get it as wrong as Newton. Unless you cite them as saying so, you are doing them no honour by saying they were as wrong as Newton was.<br /><br />Even if we live in a society that supposes Newton was right. Even if we live in a society that supposes the five ways are wrong. Even if your parish priest encourages you to attack Newton on his source citing but not on his doctrine.<br /><br />Because he too supposes Newtons first law as stated by Newton to be irrefutable, because it is "established" in the scientific community.<br /><br />Because he thinks the Catholic Church has been too much attacked as fighting science and because he thinks it needs boosting by taking credit for Newton's first law through Buridan and Philoponus, as if they were Catholics in good standing. Neither of them was considered absolutely orthodox. No Church Father thinks it a shame that Pagans should have discovered science, though some - at least one - denied science to the discovery of earth's globality.

Indeed, I have already answered that above, if you remember or trouble to review the correspondence.<br /><br />Impetus is, in any case, not just about moving objects since it envisages resistance and gravity impeding momentum leaving the body at rest and it also envisages imparting impetus to a body at rest.<br /><br />But, for the reasons I have already adumbrated, that is irrelevant to the main question which is about how Newton got the idea for his First Law.<br /><br />There may well be implications for <i>Prima Via</i> or for Deism (indeed I tend to agree with your observations thereon) but that was not the point of my post. Plagiarism was primary to that post - not secondary.<br /><br />Pretending that one has invented the idea that "projectiles persevere in their motions, so far as they are not retarded by the resistance of the air or impelled downwards by the force of gravity" when, in fact, one has got it from a medieval scientist and philosopher, is not a "minor detail" but a major one.<br /><br />Indeed, this law was - and is - arguably the basis of all modern applied science. <br /><br />It could therefore hardly be more "major".Tribunushttps://www.blogger.com/profile/17330137792269530812noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-6904816854606513132010-01-07T20:19:32.633+00:002010-01-07T20:19:32.633+00:00You missed a detail: impetus is only about moving ...You missed a detail: impetus is only about moving objects. Buridan however does not add uniformly. Also it is something which is always added, since absent from resting objects.<br /><br />Newton's inertia is about <i>uniformly</i> moving <i>or resting</i> objects. It is not necessarily added, but only if the object was previously moving otherwise or resting when now moving.<br /><br />See what the implications for Prima Via is? Or why Newton's physics makes Deism (clockworker God) thinkable.<br /><br />Beside that, I hold that the question of plagiarism is secondary.<br /><br />And plagiarism would have been intellectually dishonest in a format where every minor source for every minor detail were cited but not the major source for the major ... first law.

I agree with you when you say that ...Thanks, Hans.<br /><br />I agree with you when you say that culture is not always as coherent as the Summa, especially not the English Protestant one.<br /><br />That, I believe, was the problem.<br /><br />Verulam was not authority for dispensing with authorities and Newton was merely following Verulam's arrogance in dispensing with any authorities but himself.<br /><br />The format of the <i>Principia</i> is deficient in eschewing any sources. Medieval scientists were better scholars in that respect. Moreover, it enabled Newton to conceal his plagiarism.<br /><br />Newton's law of inertia and the law of impetus of Philoponus/Buridan are not identical but Newton's law is a clear copy of the concept of impetus.<br /><br />The difference is that whereas Buridan acknowledges his debt to Philoponus, Newton aknowledges no-one but himself and treats himself, and allows others to treat him, as the sole originator of the idea.<br /><br />As you know, Newton's First Law is:<br /><br /><i>Corpus omne perseverare in statu suo quiescendi vel movendi uniforminter in directum, nisi quatenus a viribus impressis cogiutr statum illum mutare.<br /><br />Projectilia perseverant in motibus suis nisi quatenus a resistentia aeris retardantur et vi gravitatis impelluntur deorsum. Trochus, cujus partes cohaerendo perpetuo retrahunt sese a motibus rectilineis, non cessat rotari nisi quatenus ab aere retardatur. Majora autem Planetarum et Cometarum corpora motus suos et progresivos et circulares in spatiis minus resistentibus factos conservant diutius.</i><br /><br />Or roughly (excuse my inelegant translating):<br /><br />"Every body persists in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed thereon.<br /><br />Projectiles persevere in their motions, so far as they are not retarded by the resistance of the air or impelled downwards by the force of gravity. A top, whose parts by their cohesion are perpetually drawn away from rectilinear motions, does not cease its rotation otherwise than as it is retarded by the air. The greater bodies of the planets and comets, meeting with less resistance in more free space, preserve their motions, both progressive and circular, for a much longer time."<br /><br />The idea comes direct from what Buridan taught.<br /><br />Aristotle and the peripatetics taught that a projectile continued in motion due to eddies or vibrations in the surrounding medium (antiperistasis) and, absent this proximate force, the projectile would arrive at rest almost immediately.<br /><br />Jean Buridan, following Philoponus, taught that motion was maintained by a property imparted to the projectile, which property he called “impetus” which increased with the initial motion speed and which would only be arrested by air resistance and gravity. <br /><br />In so teaching he beat Newton to the punch, anticipating modern ideas of momentum.<br /><br />Buridan wrote:<br /><br />"...after leaving the arm of the thrower, the projectile would be moved by an impetus given to it by the thrower and which would continue to be moved as long as the impetus remained stronger than the resistance, and would be of infinite duration were it not diminished and corrupted by a contrary force resisting it or by something inclining it to a contrary motion."<br /><br />Buridan was writing in the 14th century. <br /><br />Newton's <i>Principia</i> came out (1st edition) in 1687, nearly 350 years later using the same idea without any acknowledgement to the source whence he got it (i.e. Buridan).<br /><br />And THAT was my point.Tribunushttps://www.blogger.com/profile/17330137792269530812noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-87621315724597667222010-01-05T09:44:33.022+00:002010-01-05T09:44:33.022+00:00Forgot this, sorry:

But neither was it absolutely required in Academic work the centuries following Verulam. The format of Principia is not one intended for citing sources.<br /><br />Besides, between Newton and Buridan, is Buridan really equating, as Newton does, impetus with stillness as cases of non-acceleration? I hope Buridan's theory was better than Newtons, which would not be the case if Newton had plagiarised it right off.Hans Georg Lundahlhttps://www.blogger.com/profile/01055583255516264955noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-60011143622923334202010-01-05T09:26:50.150+00:002010-01-05T09:26:50.150+00:00You miss the point that a man - like Newton - may ...You miss the point that a man - like Newton - may more or less innocently be following a tradition already established a century before him, even if it ought not to have been established.

If one had, one hid it" and that this was somehow culturally "normal".<br /><br />Many of the post-Renaissance Protestant writers did away with authoriites because they knew that citing authorities soon enough tended to lead to the auto-demolition of their Protestantism. So they cheated and pretended to be blazing a new trail where authorities were no longer relevant.<br /><br />Neither the Scholastics nor the Ancients claimed the right to steal another man's ideas freely in the manner you suggest.<br /><br />Aristotle cites and rebuts Plato as Plato did with the Sophists and others. The fact that they did not do so in the way we do now does not mean that they did not do so at all, as you seem (illogically) to claim.<br /><br />The Protestant scholars were soon called to account so that it is not at all surprisng that they later were obliged to return to citing sources and authorities.<br /><br />The fact that Sir Isaac Newton got his funding from the court emphasizes my point: he did not need to cite sources to underpin his scholarship. All he needed was friends in high places in the Protestant establishment. He claimed the right merely to state his views as being authoritative in themselves - a form of arogance that is rightly eschewed today.<br /><br />To claim that this was somehow "OK" (as you put it) simply because he was a disciple of another arrogant writer unwilling to cite sources (Verulam) has but to be stated for its intrinsic and self-contradictory absurdity to be obvious.<br /><br />And it seems that I have to repeat to your Deafness that Sermons are intended for spiritual edification and are not primarily academic work requiring the citing of sources.<br /><br />In reality you are merely arguing for the sake of arguing - another unattractive characteristic of some modern scholars.Tribunushttps://www.blogger.com/profile/17330137792269530812noreply@blogger.comtag:blogger.com,1999:blog-1062692702190792942.post-79015416836190934112009-12-19T09:58:31.060+00:002009-12-19T09:58:31.060+00:00And if Suarez and St Robert Bellarmine not to ment...And if Suarez and St Robert Bellarmine not to mention Cajetan cited sources, it is because they were scholastics, like Saint Thomas Aquinas, like Buridan.<br /><br />But even they would not have cited sources in a context that called for briefness - like the sermons on Pater and Creed and Commandments by St Thomas Aquinas, he cites these documents, but not the source for every idea he propounds about them.<br /><br />Newton did NOT situate what he said about natural things "in the ongoing debate" he opted for a brief definition or proposition with just a physical explanation or giving examples. Indeed, when it comes to physical observable examples, Newton cites sources abundantly.

Notably Latin and Greek letters.<br /><br /><br />Aquinas and Buridan cited authorities. Not just sources, but sources that were authorities.<br /><br />Verulam did away with authorities, as being a kind of pseudoproof. So, ceasing to cite authorities, one ceased to cite sources.<br /><br />THEN, came the charge that this was some kind of plagiarism (which the ancients would not have admitted, since "ideas are common property, the wording is one's own" - at least as far as epics and mythology, as far as juridics and so on are concerned - philosophy being with them one place for precisely not just sources but authorities) AND one started to cite sources.<br /><br />NOT CITING a source is not the same as pretending not to have one.<br /><br />Or used not to be until funding was being put into the pot and humdrum economic justice became an issue.
