He supported it with certain conditions.<br /><br />Mather was not technically a witch-hunter as he did not, SFAIK, accuse anyone of witchcraft while they were alive. He did accuse them of witchcraft after they had been executed. Real nice for their families.<br /><br />Mather was more of a witchcraft detective, he wanted to improve the methods of identifying witches.<br /><br />His evidence for accusing one woman of witchcraft (after she was dead) included things like a cow died, and there's no natural explanation. <br /><br />He applied the same god-of-the-gaps thinking to science, which is why I count him as the first American proponent of ID. In "The Christian Philosopher" he goes on and on about "the imbecility of reason", meaning that reason can't solve all kinds of problems.<br /><br />He describes the paradox of atomic theory: if we keep slicing a material smaller and smaller, is there a point where it stops being the same material? Since no mind can resolve the paradox, that proves Christ is our Savior.<br /><br />He goes on at great length about magnets and their behavior. No mind can ever explain magnetism, that proves Christ is our Savior.<br /><br />This is the same logic, of course, no just of ID, but also of ICP, the Insane Clown Posse in their song "Miracles". That's where they rap "Fuckin' magnets-- How Do they Work?" Since no mind can ever explain magnetism, that proves it is a miracle.<br /><br />The difference is that Mather didn't attack scientists per se (just Descartes, he hated Descartes, the atheist.) <br /><br />Whereas ICP, being a product of American evangelical culture, rap in their song that scientists are LIARS and should shut up when they lie about being able to explain stuff, like you know, magnets, rainbows, blah blah.<br /><br />Mather also promoted the first American fake creationist fossil: a tooth of (what was later identified as) a mastodon, which Mather interpreted as a Biblical giant's tooth, from Genesis 6. He wrote to the Royal Society to promote this proof of Noah's Flood.<br /><br />That was understandable ignorance on Mather's part. Since then, of course, creationists have perpetrated dozens of frauds, hoaxes, and dishonestly described real fossils (like Paluxy man-prints, Calaveras skeleton, the "Black Skull of Freiberg" etc.) to prove humans and dinosaurs coexisted.<br /><br />Modern creationists are much more dishonest than Mather, and hate scientists with far greater intensity.<br />Diogeneshttps://www.blogger.com/profile/15551943619872944637noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-49017449577477643402013-01-26T08:27:13.839-05:002013-01-26T08:27:13.839-05:00Erratum: dreams AND visionsErratum: dreams AND visionsPiotr Gąsiorowskihttps://www.blogger.com/profile/06339278493073512102noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-79503890073473471282013-01-26T06:25:58.785-05:002013-01-26T06:25:58.785-05:00That was in fact Cotton Mather's logic, and Ma...<i>That was in fact Cotton Mather's logic, and Mather was, in fact, the first American to promote Intelligent Design</i><br /><br />Didn't Cotton Mather advocate the use of dreams as visions as "spiritual evidence" in court trials?Piotr Gąsiorowskihttps://www.blogger.com/profile/06339278493073512102noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-13817565478408537492013-01-26T06:22:10.687-05:002013-01-26T06:22:10.687-05:00A really nice job, Diogenes! Of course what you de...A really nice job, Diogenes! Of course what you define is the fundamental machinery of science -- how theories are built and tested. Science as done on the everyday life of scientists is mostly about the use of models derived from general theories to solve more specific problems (such as explaining any results of ongoing observations in terms of what we already know).<br /><br />Also, "general" is a relative term. Is biology a science if its area of study is something as parochial as life on Earth? In the Milky Way alone here may be several billion planets that might support some form of "life", but we have no "universal theories" of life on a cosmic scale. By contrast, the applicability of the known laws of physics or chemistry extends as far as the observable universe. Still, I don't think anybody here doubts that biology is an important and successful discipline of science despite its local scope.Piotr Gąsiorowskihttps://www.blogger.com/profile/06339278493073512102noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-20018397114906029702013-01-25T19:27:31.627-05:002013-01-25T19:27:31.627-05:00Oberski: "God makes it so" has the immed...Oberski: <i>"God makes it so" has the immediate detrimental effect of stopping any further investigation into the theory while the admission that "I don't know" opens up the theory to more investigation.</i><br /><br />But that's a sociological judgment, and ID "scholars" of the (alleged) history of science would disagree, asserting that historically, science is supposedly based on Christianity. <br /><br />So then you that drags you into arguments over the history of science, e.g. does it matter that Newton believed in God? etc. They will never, ever concede that point.<br /><br />Steve Fuller, the pro-ID sociologist who testified at Dover and blathers in "Expelled", would disagree with you and say that the history of science shows that "God makes it so" inspired great geniuses, blah blah. Therefore ID deserves NOT to be expected to make testable predictions, as a form of "affirmative action" [Fuller's exact phrase] to correct for discrimination against theists. <br /><br />That actually is an accurate description of Fuller's beliefs: ID should not be expected to make testable predictions-- we should lower or eliminate our standards for ID-- but, says Fuller, we should pretend or act as if ID really is science anyway, because oh, it's "affirmative action" [yes, he did say that] for theists, they deserve it, they need affirmative action.<br /><br />John <a href="http://thequestionableauthority.blogspot.com/2005/12/desparate-pathetic-and-disgusting-dis.html" rel="nofollow">"Quote-Miner"</a> West would argue also, so would Klinghitler, bringing up the names of dead white men (DWM's) who believed in God, all veddy intellectual.<br /><br />I don't want to argue about history of science. I want to define the scientific method, and make clear what happens if you redefine it. <br /><br />If you redefine the scientific method even a little, "my cow died" leads straight to: "My neighbor's a witch." <br /><br />That was in fact Cotton Mather's logic, and Mather was, in fact, the first American to promote Intelligent Design [see "The Christian Philosopher."]Diogeneshttps://www.blogger.com/profile/15551943619872944637noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-79438084950828898302013-01-25T18:53:57.388-05:002013-01-25T18:53:57.388-05:00@Diogenes

Intellige...By the way, in case it's not clear:<br /><br />Intelligent Design is not science because, as a theory, it does not emit testable predictions. Expressed as an algorithm, "God makes it so" has the same algorithmic form as "I don't know." They both emit the same number of testable predictions: ZERO.<br /><br />Young Earth creationism would be falsified, if we compared the HONEST predictions of the Noah's Flood model against observed geological, paleontological, etc. facts, the HONEST predictions of YEC would not match up to the data.<br /><br />However, <b>Young Earth & Old Earth creationism are PSEUDOSCIENCE</b>, which I define as distinct from science. <br /><br />Pseudoscience is defined as a set of theories whose claimed predictions DO NOT follow from the hypothesis as described, i.e. the claimed predictions are not honest. For example: when Young Earth creationists look at 1,000 feet thick layer of chalk [mostly foraminifera fossils] at the White Cliffs of Dover, and creationists say, "Oh yes, our Noah's Flood theory predicts there should be a stack of foraminifera fossils in chalk 1,000 feet thick formed in 3 days or so during the year of Noah's Flood."<br /><br />Naw. That's not an honest prediction of your theory, expressed as an algorithm. If you lie about the predictions that come from your theory, expressed in its simplest form, it's pseudoscience.<br /><br />Diogeneshttps://www.blogger.com/profile/15551943619872944637noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-8657568111525231382013-01-25T17:30:28.330-05:002013-01-25T17:30:28.330-05:00Continuing...

However, I disagree.<br /><br />I believe that improvements in statistical theory will make this trade-off totally objective in the future, especially if we apply Kolmogorov information theory to scientific <b>theories expressed as ALGORITHMS.</b><br /><br />Here is an example of an OBJECTIVE method of deciding between the competing interests of 1a, 1b, and 1c: the <b>chi-squared statistical test</b>, which is used to discriminate between different polynomial models of varying complexity: for example, consider fitting predictions Yi given some observed inputs Xi, where the predictions Yi should match observed values Y'i.<br /><br />Here we could float various polynomial models:<br />Constant: Yi = A<br />Linear: Yi = A + BXi<br />Quadratic: Yi = A + BXi + CXi^2<br />Cubic: Yi = A + BXi + CXi^2 + DXi^3<br /><br />etc., you get the idea. An infinite number of models is conceivable. Obviously, more complex models will produce a better fit between predictions and data. However, Occam's razor demands that we don't want an over-complex theory; they're not robust. You have competing interests between model simplicity and accuracy of predictions.<br /><br />So you do a chi-squared test, which objectively compromises between the competing interests of model simplicity and predictive accuracy.<br /><br />Since this is possible in the case of the chi-squared test, I conclude that in the future, statistical theory and Kolmogorov information theory will resolve the competing interests of simplicity and predictive power.<br />Diogeneshttps://www.blogger.com/profile/15551943619872944637noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-25898551092881985232013-01-25T17:29:30.735-05:002013-01-25T17:29:30.735-05:00Listen up punks, here's the definition of what...Listen up punks, here's the definition of what science is.<br /><br /><b>DEFINITION OF SCIENCE:</b><br />Science consists of two things: <br />1. selection of general/universal laws of nature via the scientific method [see def'n below] which is a competition between theories based on the fit between observable quantities and the testable predictions that theories emit; and<br /><br />2. Induction; or, application of the general principles thus found, often via analogy.<br /><br />Example of 1. Observe positions of some planets, input them to Newton's theory of gravity, make testable predictions, compare them to observations. See if Newton's theory beats, e.g., Aristotelian model. <br />Example of 2. Apply Newton's theory of gravity to solve for angle theta at which cannon should be tilted so that cannonballs fired from cannon will fall on enemy troops.<br /><br />Engineering consists entirely of 2, induction. No scientific method, no competition between theories that model universal laws.<br /><br />Medicine consists of applying 2. induction, and also 1, scientific method, particularly while diagnosing the cause of diseases. However, medicine is NOT science because: it does apply the scientific method to competing hypotheses of causes of diseases, but the hypotheses describe specific instances of disease, not general/ universal principles.<br /><br />Ditto plumbing: applies 2, induction, and uses 1, scientific method, but still NOT science. Plumbers may apply the scientific method to competing hypotheses of the source of a water leak, but again, the hypotheses describe specific instances of water leaks, not general/ universal principles of hydrology etc.<br /><br /><b>DEFINITION OF THE SCIENTIFIC METHOD:</b><br />A competition between theories which are <b>EXPRESSED AS ALGORITHMS</b> that input observable quantities [X] and output predictions that can be compared to other observable quantities [Y].<br />(Note: X and Y must be independent, if not you get circular logic and patholocial science.)<br /><br />The winner of the competition between theories is judged by two criteria.<br /><br />1. Predictive power: fit between testable predictions and observable quantities.<br /><br />2. Simplicity of theory / Kolmogorov-Chaitin complexity of algorithm / Minimal Description Length (MDL). [Occam's Razor goes here].<br /><br />Complication: Predictive power is judged by three criteria.<br /><br />1a. Accuracy: distance between prediction and observation.<br />1b. Specificity of prediction. [Does theory accommodate all conceivable data? Or does it exclude some?]<br />1c. Precision of observed data. [Are observed data known with great experimental precision or crappy and approximate?]<br /><br />1a, 1b, and 1c are competing interests, and one might argue that the trade-off between them will be forever subjective. However, I disagree, as I explain below.<br />Diogeneshttps://www.blogger.com/profile/15551943619872944637noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-20115008008375626202013-01-25T11:12:35.499-05:002013-01-25T11:12:35.499-05:00Not at all, he just thought something through, and...Not at all, he just thought something through, and thought it through, many argue, better than anyone else in the world had managed, but then changed his mind and explained how and why he was wrong.<br /><br />Re this topic, the kind of question being discussed, and the mistakes being made, were fairly central to his later philosophy.
