Math in Laputa

The third part of Jonathan Swift's book Gulliver's Travels (1726) has the title A voyage to Laputa, Balnibarbi, Luggnagg, Glubbdubdrib, and Japan . Mathematics turns out to play an important role in Laputa, as will be evident from the quotations below. I was led to this by an article Zeggen wat niet is by H. Brandt Corstius in NRC Handelsblad, 29 March 1996.

The king should not be distracted while solving math problems

At last we entered the palace, and proceeded into the chamber of presence, where I saw the King seated on his throne, attended on each side by persons of prime quality. Before the throne was a large table filled with globes and spheres, and mathematical instruments of all kinds. His Majesty took not the least notice of us, although our entrance was not without sufficient noise, by the concourse of all persons belonging to the court. But he was then deep in a problem, and we attended at least an hour, before he could solve it. There stood by him on each side a young page, with flaps in their hands, and when they saw he was at leisure, one of them gently struck his mouth, and the other his right ear; at which he started like one awakened on the sudden, and looking towards me and the company I was in, recollected the occasion of our coming, whereof he had been informed before. He spoke some words, whereupon immediately a young man with a flap came up to my side, and flapped me gently on the right ear; but I made signs, as well as I could, that I had no occasion for such an instrument; which, as I afterwards found, gave his Majesty and the whole court a very mean opinion of my understanding.

Food served in the form of mathematical figures

My dinner was brought, and four persons of quality, whom I remembered to have seen very near the King's person, did me the honor to dine with me. We had two courses of three dishes each. In the first course there was a shoulder of mutton, cut into an equilateral triangle, a piece of beef into a rhomboides, and a pudding into a cycloid. The second course was two ducks, trussed up into the form of fiddles; sausages and puddings resembling flutes and hautboys, and a breast of veal in the shape of a harp. The servants cut our bread into cones, cylinders, parallelograms, and several other mathematical figures.

They praise the beauty of a woman in geometrical terms

The knowledge I had in mathematics gave me great assistance in acquiring their phraseology, which depended much upon that science and music; and in the latter I was not unskilled. Their ideas are perpetually conversant in lines and figures. If they would, for example, praise the beauty of a woman, or any other animal, they describe it by rhombs, circles, parallelograms, ellipses, and other geometrical terms, or by words of art drawn from music, needless here to repeat. I observed in the King's kitchen all sorts of mathematical and musical instruments, after the figures of which they cut up the joints that were served to his Majesty's table.

Their narrow-mindedness and clumsiness in practical matters

Their houses are very ill built, the walls bevel without one right angle in any apartment, and this defect arises from the contempt they bear to practical geometry, which they despise as vulgar and mechanic, those instructions they give being too refined for the intellectuals of their workmen, which occasions perpetual mistakes. And although they are dexterous enough upon a piece of paper in the management of the rule, the pencil, and the divider, yet in the common actions and behavior of life, I have not seen a more clumsy, awkward, and unhandy people, nor so slow and perplexed in their conceptions upon all other subjects, except those of mathematics and music. They are very bad reasoners, and vehemently given to opposition, unless when they happen to be of the right opinion, which is seldom their case. Imagination, fancy, and invention, they are wholly strangers to, nor have any words in their language by which those ideas can be expressed; the whole compass of their thoughts and mind being shut up within the two forementioned sciences.
(from Chapter II)

The strong disposition of mathematicians towards politics

Most of them, and especially those who deal in the astronomical part, have great faith in judicial astrology, although they are ashamed to own it publicly. But what I chiefly admired, and thought altogether unaccountable, was the strong disposition I observed in them towards news and politics, perpetually enquiring into public affairs, giving their judgments in matters of state, and passionately disputing every inch of a party opinion. I have indeed observed the same disposition among most of the mathematicians I have known in Europe, although I could never discover the least analogy between the two sciences; unless those people suppose, that because the smallest circle hath as many degrees as the largest, therefore the regulation and management of the world require no more abilities than the handling and turning of a globe. But I rather take this quality to spring from a very common infirmity of human nature, inclining us to be more curious and conceited in matters where we have least concern, and for which we are least adapted either by study or nature.
(from Chapter II)

The husband, so rapt in speculation, is easily deceived by his wife

The women of the island have abundance of vivacity: they contemn their husbands, and are exceedingly fond of strangers, whereof there is always a considerable number from the continent below, attending at court, either upon affairs of the several towns and corporations, or their own particular occasions, but are much despised, because they want the same endowments. Among these the ladies choose their gallants: but the vexation is, that they act with too much ease and security, for the husband is always so rapt in speculation, that the mistress and lover may proceed to the greatest familiarities before his face, if he be but provided with paper and implements, and without his flapper at his side.
(from Chapter II)

The narrow interests of the king

In about a month's time I had made a tolerable proficiency in their language, and was able to answer most of the King's questions, when I had the honor to attend him. His Majesty discovered not the least curiosity to inquire into the laws, government, history, religion, or manners of the countries where I had been, but confined his questions to the state of mathematics, and received the account I gave him with great contempt and indifference, though often roused by his flapper on each side.
(from Chapter II)

Their contempt for people less talented in math

Although I cannot say that I was ill treated in this island, yet I must confess I thought myself too much neglected, not without some degree of contempt. For neither prince nor people appeared to be curious in any part of knowledge, except mathematics and music, wherein I was far their inferior, and upon that account very little regarded.
(from Chapter IV)

An interesting teaching method

I was at the mathematical school, where the master taught his pupils after a method scarce imaginable to us in Europe. The proposition and demonstration were fairly written on a thin wafer, with ink composed of a cephalic tincture. This the student was to swallow upon a fasting stomach, and for three days following eat nothing but bread and water. As the wafer digested, the tincture mounted to his brain, bearing the proposition along with it. But the success has not hitherto been answerable, partly by some error in the quantum or composition, and partly by the perverseness of lads, to whom this bolus is so nauseous, that they generally steal aside, and discharge it upwards before it can operate; neither have they been yet persuaded to use so long an abstinence as the prescription required.
(from Chapter V)

Mathematical explanations of nature will not persist

He (Aristotle) said, that new systems of nature were but new fashions, which would vary in every age; and even those who pretend to demonstrate them from mathematical principles, would flourish but a short period of time, and be out of vogue when that was determined.
