“Some writers maintain arithmetic to be only the only sure guide in political economy; for my part, I see so many detestable systems built upon arithmetical statements, that I am rather inclined to regard that science as the instrument of national calamity.”

“There is reason, however, to think that the author would have rendered it much more interesting, and have carried it to si higher degree of perfection, had he lived in an age more enlightened and better informed in regard to the mathematics and natural philosophy. Since the death of that mathematician, indeed, the arts and sciences have been so much improved, that what in his time might have been entitled to the character of mediocrity, would not at present be supportable. How many new discoveries in every part of philosophy? How many new phenomena observed, some of which have even given birth to the most fertile branches of the sciences? We shall mention only electricity, an inexhaustible source of profound reflection, and of experiments highly amusing. Chemistry also is a science, the most common and slightest principles of which were quite unknown to Ozanam. In short, we need not hesitate to pronounce that Ozanam's work contains a multitude of subjects treated of with an air of credulity, and so much prolixity, that it appears as if the author, or rather his continuators, had no other object in view than that of multiplying the volumes.
To render this work, then, more worthy of the enlightened agt in which we live, it was necessary to make numerous corrections and considerable additions. A task which we have endeavoured to discharge with all diligence”

“Today, I would like to provide the American people with an update on the White House transition and our policy plans for the first 100 days. Our transition team is working very smoothly, efficiently, and effectively. Truly great and talented men and women, patriots indeed are being brought in and many will soon be a part of our government, helping us to Make America Great Again. My agenda will be based on a simple core principle: putting America First. Whether it's producing steel, building cars, or curing disease, I want the next generation of production and innovation to happen right here, in our great homeland: America – creating wealth and jobs for American workers. As part of this plan, I've asked my transition team to develop a list of executive actions we can take on day one to restore our laws and bring back our jobs. It's about time. These include the following: On trade, I am going to issue our notification of intent to withdraw from the Trans-Pacific Partnership, a potential disaster for our country. Instead, we will negotiate fair, bilateral trade deals that bring jobs and industry back onto American shores. On energy, I will cancel job-killing restrictions on the production of American energy – including shale energy and clean coal – creating many millions of high-paying jobs. That's what we want, that's what we've been waiting for. On regulation, I will formulate a rule which says that for every one new regulation, two old regulations must be eliminated, it's so important. On national security, I will ask the Department of Defense and the Chairman of the Joint Chiefs of Staff to develop a comprehensive plan to protect America's vital infrastructure from cyber-attacks, and all other form of attacks. On immigration, I will direct the Department of Labor to investigate all abuses of visa programs that undercut the American worker. On ethics reform, as part of our plan to Drain the Swamp, we will impose a five-year ban on executive officials becoming lobbyists after they leave the Administration – and a lifetime ban on executive officials lobbying on behalf of a foreign government. These are just a few of the steps we will take to reform Washington and rebuild our middle class. I will provide more updates in the coming days, as we work together to Make America Great Again for everyone.”

“The German Rendering. The German language was divided into as many dialects as tribes and states, and none served as a bond of literary union. Saxons and Bavarians, Hanoverians and Swabians, could scarcely understand each other. Each author wrote in the dialect of his district, Zwingli in his Schwyzerdütsch. "I have so far read no book or letter," says Luther in the preface to his version of the Pentateuch (1523), in which the German language is properly handled. Nobody seems to care sufficiently for it; and every preacher thinks he has a right to change it at pleasure, and to invent new terms." Scholars preferred to write in Latin, and when they attempted to use the mother tongue, as Reuchlin and Melanchthon did occasionally, they fell far below in ease and beauty of expression.
Luther brought harmony out of this confusion, and made the modern High German the common book language. He chose as the basis the Saxon dialect, which was used at the Saxon court and in diplomatic intercourse between the emperor and the estates, but was bureaucratic, stiff, heavy, involved, dragging, and unwieldy. He popularized and adapted it to theology and religion. He enriched it with the vocabulary of the German mystics, chroniclers, and poets. He gave it wings, and made it intelligible to the common people of all parts of Germany.”

“Some excuse seems necessary for the pain and loss which we occasion to brutes, by restraining them of their liberty, mutilating their bodies, and, at last, putting an end to their lives (which we suppose to be the whole of their existence), for our pleasure or conveniency.
The reasons alleged in vindication of this practice, are the following: that the several species of brutes being created to prey upon one another, affords a kind of analogy to prove that the human species were intended to feed upon them; that, if let alone, they would overrun the earth, and exclude mankind from the occupation of it; that they are requited for what they suffer at our hands, by our care and protection.
Upon which reasons I would observe, that the analogy contended for is extremely lame; since brutes have no power to support life by any other means, and since we have; for the whole human species might subsist entirely upon fruit, pulse, herbs, and roots, as many tribes of Hindoos actually do. The two other reasons may be valid reasons, as far as they go; for, no doubt, if man had been supported entirely by vegetable food, a great part of those animals which die to furnish his table, would never have lived: but they by no means justify our right over the lives of brutes to the extent in which we exercise it. What danger is there, for instance, of fish interfering with us, in the occupation of their element? or what do we contribute to their support or preservation?”

“We drove 22 miles into the country around Farmington. There were meadows and apple orchards. White fences trailed through the rolling fields. Soon the sign started appearing. THE MOST PHOTOGRAPHED BARN IN AMERICA. We counted five signs before we reached the site. There were 40 cars and a tour bus in the makeshift lot. We walked along a cowpath to the slightly elevated spot set aside for viewing and photographing. All the people had cameras; some had tripods, telephoto lenses, filter kits. A man in a booth sold postcards and slides -- pictures of the barn taken from the elevated spot. We stood near a grove of trees and watched the photographers. Murray maintained a prolonged silence, occasionally scrawling some notes in a little book. "No one sees the barn," he said finally. A long silence followed. "Once you've seen the signs about the barn, it becomes impossible to see the barn." He fell silent once more. People with cameras left the elevated site, replaced by others. We're not here to capture an image, we're here to maintain one. Every photograph reinforces the aura. Can you feel it, Jack? An accumulation of nameless energies." There was an extended silence. The man in the booth sold postcards and slides. "Being here is a kind of spiritual surrender. We see only what the others see. The thousands who were here in the past, those who will come in the future. We've agreed to be part of a collective perception. It literally colors our vision. A religious experience in a way, like all tourism."”

Another silence ensued. "They are taking pictures of taking pictures," he said.”

“On symbolic use of equalities and proportions. Chapter II.
The analytical method accepts as proven the most famous [ as known from Euclid ] symbolic use of equalities and proportions that are found in items such as:
1. The whole is equal to the sum of its parts.
2. Quantities being equal to the same quantity have equality between themselves. [a = c & b = c => a = b]
3. If equal quantities are added to equal quantities the resulting sums are equal.
4. If equals are subtracted from equal quantities the remains are equal.
5. If equal equal amounts are multiplied by equal amounts the products are equal.
6. If equal amounts are divided by equal amounts, the quotients are equal.
7. If the quantities are in direct proportion so also are they are in inverse and alternate proportion. [a:b::c:d=>b:a::d:c & a:c::b:d]
8. If the quantities in the same proportion are added likewise to amounts in the same proportion, the sums are in proportion. [a:b::c:d => (a+c):(b+d)::c:d]
9. If the quantities in the same proportion are subtracted likewise from amounts in the same proportion, the differences are in proportion. [a:b::c:d => (a-c):(b-d)::c:d]
10. If proportional quantities are multiplied by proportional quantities the products are in proportion. [a:b::c:d & e:f::g:h => ae:bf::cg:dh]
11. If proportional quantities are divided by proportional quantities the quotients are in proportion. [a:b::c:d & e:f::g:h => a/e:b/f::c/g:d/h]
12. A common multiplier or divisor does not change an equality nor a proportion. [a:b::ka:kb & a:b::(a/k):(b/k)]
13. The product of different parts of the same number is equal to the product of the sum of these parts by the same number. [ka + kb = k(a+b)]
14. The result of successive multiplications or divisions of a magnitude by several others is the same regardless of the sequential order of quantities multiplied times or divided into that magnitude.
But the masterful symbolic use of equalities and proportions which the analyst may apply any time is the following:
15. If we have three or four magnitudes and the product of the extremes is equal to the product means, they are in proportion. [ad=bc => a:b::c:d OR ac=b2 => a:b::b:c]
And conversely
10. If we have three or four magnitudes and the first is to the second as the second or the third is to the last, the product of the extremes is equal to that of means. [a:b::c:d => ad=bc OR a:b::b:c => ac=b2]
We can call a proportion the establishment of an equality [equation] and an equality [equation] the resolution of a proportion.”

“I have grown accustomed to the disrespect expressed by some of the participants for their colleagues in the other disciplines. "Why, Dan," ask the people in artificial intelligence, "do you waste your time conferring with those neuroscientists? They wave their hands about 'information processing' and worry about where it happens, and which neurotransmitters are involved, but they haven't a clue about the computational requirements of higher cognitive functions." "Why," ask the neuroscientists, "do you waste your time on the fantasies of artificial intelligence? They just invent whatever machinery they want, and say unpardonably ignorant things about the brain." The cognitive psychologists, meanwhile, are accused of concocting models with neither biological plausibility nor proven computational powers; the anthropologists wouldn't know a model if they saw one, and the philosophers, as we all know, just take in each other's laundry, warning about confusions they themselves have created, in an arena bereft of both data and empirically testable theories. With so many idiots working on the problem, no wonder consciousness is still a mystery. All these charges are true, and more besides, but I have yet to encounter any idiots. Mostly the theorists I have drawn from strike me as very smart people – even brilliant people, with the arrogance and impatience that often comes with brilliance – but with limited perspectives and agendas, trying to make progress on the hard problems by taking whatever shortcuts they can see, while deploring other people's shortcuts. No one can keep all the problems and details clear, including me, and everyone has to mumble, guess and handwave about large parts of the problem.”

“In a Thumbnail Sketch here is [the Multiple Drafts theory of consciousness] so far:There is no single, definitive "stream of consciousness," because there is no central Headquarters, no Cartesian Theatre where "it all comes together" for the perusal of a Central Meaner. Instead of such a single stream (however wide), there are multiple channels in which specialist circuits try, in parallel pandemoniums, to do their various things, creating Multiple Drafts as they go. Most of these fragmentary drafts of "narrative" play short-lived roles in the modulation of current activity but some get promoted to further functional roles, in swift succession, by the activity of a virtual machine in the brain. The seriality of this machine (its "von Neumannesque" character) is not a "hard-wired" design feature, but rather the upshot of a succession of coalitions of these specialists.The basic specialists are part of our animal heritage. They were not developed to perform peculiarly human actions, such as reading and writing, but ducking, predator-avoiding, face-recognizing, grasping, throwing, berry-picking, and other essential tasks. They are often opportunistically enlisted in new roles, for which their talents may more or less suit them. The result is not bedlam only because the trends that are imposed on all this activity are themselves part of the design. Some of this design is innate, and is shared with other animals. But it is augmented, and sometimes even overwhelmed in importance, by microhabits of thought that are developed in the individual, partly idiosyncratic results of self-exploration and partly the predesigned gifts of culture. Thousands of memes, mostly borne by language, but also by wordless "images" and other data structures, take up residence in an individual brain, shaping its tendencies and thereby turning it into a mind.”

“Permit me, Sir, to add another circumstance in our colonies, which contributes no mean part towards the growth and effect of this untractable spirit. I mean their education. In no country perhaps in the world is the law so general a study. The profession itself is numerous and powerful; and in most provinces it takes the lead. The greater number of the deputies sent to the congress were lawyers. But all who read, and most do read, endeavour to obtain some smattering in that science. I have been told by an eminent bookseller, that in no branch of his business, after tracts of popular devotion, were so many books as those on the law exported to the plantations. The colonists have now fallen into the way of printing them for their own use. I hear that they have sold nearly as many of Blackstone's Commentaries in America as in England. General Gage marks out this disposition very particularly in a letter on your table. He states, that all the people in his government are lawyers, or smatterers in law; and that in Boston they have been enabled, by successful chicane, wholly to evade many parts of one of your capital penal constitutions. The smartness of debate will say, that this knowledge ought to teach them more clearly the rights of legislature, their obligations to obedience, and the penalties of rebellion. All this is mighty well. But my honourable and learned friend on the floor, who condescends to mark what I say for animadversion, will disdain that ground. He has heard, as well as I, that when great honours and great emoluments do not win over this knowledge to the service of the state, it is a formidable adversary to government. If the spirit be not tamed and broken by these happy methods, it is stubborn and litigious. Abeunt studia in mores. This study renders men acute, inquisitive, dexterous, prompt in attack, ready in defence, full of resources. In other countries, the people, more simple, and of a less mercurial cast, judge of an ill principle in government only by an actual grievance; here they anticipate the evil, and judge of the pressure of the grievance by the badness of the principle. They augur misgovernment at a distance; and snuff the approach of tyranny in every tainted breeze.”

“Quite distinct from the theoretical question of the manner in which mathematics will rescue itself from the perils to which it is exposed by its own prolific nature is the practical problem of finding means of rendering available for the student the results which have been already accumulated, and making it possible for the learner to obtain some idea of the present state of the various departments of mathematics…. The great mass of mathematical literature will be always contained in Journals and Transactions, but there is no reason why it should not be rendered far more useful and accessible than at present by means of treatises or higher text-books. The whole science suffers from want of avenues of approach, and many beautiful branches of mathematics are regarded as difficult and technical merely because they are not easily accessible…. I feel very strongly that any introduction to a new subject written by a competent person confers a real benefit on the whole science. The number of excellent text-books of an elementary kind that are published in this country makes it all the more to be regretted that we have so few that are intended for the advanced student. As an example of the higher kind of text-book, the want of which is so badly felt in many subjects, I may mention the second part of Prof. Chrystal’s “Algebra” published last year, which in a small compass gives a great mass of valuable and fundamental knowledge that has hitherto been beyond the reach of an ordinary student, though in reality lying so close at hand. I may add that in any treatise or higher text-book it is always desirable that references to the original memoirs should be given, and, if possible, short historic notices also. I am sure that no subject loses more than mathematics by any attempt to dissociate it from its history.”

De vós, se irão convosco eternizando.<p>De Cristo a injusta morte vingou Tito
Na de Jerusalém total ruína:
E a vós, a quem Deus deu um peito invito,
Ser vingador de sua Fé destina.
Extinguir do Agareno o falso rito
É de vosso valor a empresa dina:
Tomai pois o bastão da empresa grande
Para o tempo que o Céu marchar vos mande.

“The distinction between micro- and macro inventions matters because they appeared to be governed by different laws. Microinventions generally result from an intentional search for improvements, and are understandable -if not predictable- by economic forces. They are guided, at least to some extent, by the laws of supply and demand and by the intensity of search and the resources committed to them, and thus by signals emitted by the price mechanism. Furthermore, in so far as micro inventions are the by-products of experience through learning by doing or learning by using they are correlated with output or investment. Macroinventions are more difficult to understand, and seem to be governed by individual genius and luck as much as by economic forces. Often they are based on some fortunate event, in which an inventor stumbles on one thing while looking for another, arrives at the right conclusion for the wrong reason, or brings to bear a seemingly unrelated body of knowledge that just happen to hold the clue to the right solution. The timing of these inventions is consequently often hard to explain. Much of the economic literature dealing with the generation of technological progress through market mechanisms and incentive devices thus explain only part of the story. This does not mean that we have to give up the attempt to try to understand macroinventions. We must, however, look for explanations largely outside the trusted and familiar market mechanisms relied upon by economists.”
