Mathematics, Decolonization and Censorship: C. K. Raju

Guest post by C.K.RAJU
Did you find math difficult in school? Does your child? If so, what is the solution: change the teacher or change the child? Blaming the teacher or the child for math difficulties is a common but unsound explanation. Thus, problems with teachers or students should equally affect all subjects, not only math.The right solution is to change math. That seems impossible. People naively believe that math is universal. In fact, the math taught today, from middle school onward, is called formal math; it began only in the 20th c. with David Hilbert and Bertrand Russell. It differs from the normal math which people earlier did for thousands of years, across the world, and still do in kindergarten.Formal math adds enormously to the difficulty of math but nothing to its practical value. The practical value of math comes from efficient techniques of calculation, used in normal math, not prolix formal proofs. For example, the proof of 1+1=2 took Whitehead and Russell 368 pages of dense symbolism in their Principia. That proof is a liability in a grocer’s shop. In contrast, normal math is easy. One apple and one apple make two apples as most people learn in kindergarten. So should we switch back to normal math at all levels?

Russell

Now our school texts justify the teaching of formal math as follows. The class 9 math text of NCERT1 (or of various states). tells the story of an early Greek called Euclid who was the first to do math “systematically” using deductive reasoning. The text further asserts that this was something that all others in Egypt, India, Iraq, China, and South America failed to do. It shows children an image of Euclid as a white man. On this story, students are told, we must do math by imitating “Euclid” who is glorified as the father of “real” math (meaning formal math).

The story condemns normal math as inferior. But no real argument is advanced to support the purported superiority of formal math, just a story. Do children check it? No; but the story is false. To expose its falsehood, I have offered a prize of Rs 2 lakhs for any serious (primary) evidence about Euclid. This prize stands unclaimed for several years. Why? Experts know2 there is nil evidence for “Euclid” and much counter-evidence.

Our own “experts”—the one’s who wrote the NCERT text—are unable to produce the evidence when challenged. They should either accept their mistakes, or defend their claims publicly, but do neither. Since we are totally dependent on such “experts” we just carry on with the wrong school texts! The vested interests involved are, however, deeper than just the vanity of “experts”, or their desire to preserve their jobs. Hence, attempts to publicly challenge the story of “Euclid” or to challenge the related philosophy of formal math are often censored.

As just one example of censorship, I wrote an article, “To decolonise math, stand up to its false history and bad philosophy”. This was published in the Conversation (global edition) in Oct 2016. The article created a stir. It went viral and recorded some 17K hits (60% in US and Africa) before it was abruptly removed by the South Africa editor. If there was something wrong in the article, the Conversation should have carried a public correction. No one was able to point to any actual error. So, the removal was privately justified on the lame editorial ground that I had “sited” (sic) my own work, such as my book.3 Even in India, the article was first reproduced and then taken down by both The Wire and Scroll, though to the credit of The Wire it put the article back with an apology. Currently, that censored article is available on my blog,4 on The Wire,5 and on Science2.0.6 It was also recently reproduced in full as part of another peer-reviewed journal article,7 so, again, there was nothing obviously wrong with it.

So, why was it censored? Why are false myths and censorship so essential to the teaching of math?

The answer involves three unpleasant facts. First, this way of teaching math came to us through colonial education, which was 100% church education when it first came to India in the 19th c.: not only mission schools, but all early Western universities such as Oxford and Cambridge were created by the church, and remained fully under its control till then.

Second, “Euclid’s” supposedly “superior” way of doing geometry was taught as part of the church curriculum for centuries. Why? That curriculum was designed to create missionaries. Future missionaries were taught the ability to persuade others: they were taught to use reason to persuade those who rejected the Christian scriptures. Hence, the church used math to teach reasoning, not practical calculation.

The third and least known fact is this: the word “reason” involves a tricky double speak. It does NOT refer to ordinary ways of reasoning, as people are easily tricked into believing. Rather it refers to a special way of reasoning developed by the church to support its “theology of reason” (which it adopted during the Crusades). Briefly, the church divorced reason from empirical facts. It had good reason to do so. Empirical facts are contrary to church dogmas: the notions of God, heaven, hell, resurrection, virgin birth are all contrary to the empirical. To defend its anti-empirical dogmas, the church declared empirical proofs to be inferior. It declared that “pure deductive proofs” based on reason, but divorced from facts, are infallible and “superior”. This church doctrine of reason is exactly what our school texts promote through the story of “Euclid” and his “superior” deductive proofs. Incidentally, that story also serves to hide the relation to church dogma.

Since the church used the book Elements as a textbook, its author had to be theologically correct, and early Greeks were the only people whom the church acknowledged as its “friends”. Hence, the author of the book was declared to be an unknown early Greek. The church never appointed a black or woman as pope, and it would have egg all over its face if it acknowledged the true author of the Elements as a heretical black woman who was raped and brutally killed in a church, as I asserted in my censored article. Science 2.0 did change the title of my article to “Was Euclid a black woman”, but did not add the part about her being lynched for being heretical.

The church used the book Elements by grossly “reinterpreting” the original. It was falsely asserted that the book contained pure deductive proofs, aligned to the church theology of using reason divorced from the empirical. This assertion, repeated by our school texts, is brazenly contrary to facts. The actual fact is that the book Elements does NOT have a single such pure deductive proof from its very first proposition to the last. Ironically, this itself shows how terribly fallible deductive proofs are—for centuries, invalid deductive proofs were wrongly accepted as valid by ALL Western scholars. When this truth was inevitably acknowledged, at the beginning of the 20th c., a quick substitute had to be invented to save Western pride from crumbling at a time when it was at its zenith.

The substitute for “Euclidean” math, invented by the West at the turn of the 20th c., was the formal mathematics of Hilbert and Russell. Russell’s proof of 1+1=2 is so complicated because one is not allowed to point out empirically that one apple and one apple make two apples. Formal mathematics mimics church dogma; it prohibits the use of the empirical, on the belief that the prohibition of the empirical leads to some “superior” form of truth.

This belief is pure balderdash. In fact, reason divorced from facts can be used to prove any nonsense whatsoever. To show this, I gave the example of the horned rabbit in my censored article. (1) All animals have two horns. (2) A rabbit is an animal, therefore, (3) a rabbit has two horns. Of course the conclusion is nonsense, and so is the premise (1). But we know that only as an empirical fact; if all reference to empirical facts is prohibited we have no way of knowing the truth or falsehood of premise (1). As Russell put it, in formal math we “take any hypothesis that seems amusing, and deduce its consequences”,8 and I am distinctly amused by the hypothesis that all animals have two horns, and its deduced consequences for rabbits. It illustrates the conclusions based on pure deduction which the church glorifies as infallible.

Others used reasoning differently together with empirical proof. For example, in India all traditional schools of philosophy accepted the empirical (pratyaksa) as the first means of proof. This was also true of traditional Indian math (normal math) from the time of the sulba sutras.9

Now, indoctrinated colonised minds often conflate acceptance of empirical with rejection of reasoning. But that is not true: like science, most systems of Indian philosophy, and traditional Indian math, accepted both empirical proofs and reasoning. The only exception was the Lokayata, or people’s philosophers, who warned against inference not based on the empirical. Their example of wolf’s paws is similar to the example of the horned rabbit above: on seeing the pug marks of a wolf, people in a city inferred that a wolf was around. Actually the pug marks were made by a man to demonstrate the foolishness of inference not based on sound empirical facts.

But this foolish dogma that avoiding empirical facts leads to a higher form of truth is what we still teach today. Early in middle school, children are introduced to formal math and avoidance of empirical as follows: the NCERT class 6 text asserts that a geometric point is invisible. It adds that a point determines a location. At two recent workshops, I asked a number of school math teachers and students how do they know what location a point determines since the point is invisible. They had no answer. But they had the honesty to admit their ignorance, unlike colonised intellectuals and “experts” who will defend the doctrine of invisible points exactly like the courtiers who defended the emperor’s invisible new clothes.

Many people say that math is difficult because it is abstract. This is wrong. The word dog is an abstraction, for dogs are of varying sizes and shapes. But children have no difficulty in understanding the abstraction “dog”, for one can easily point to a dog. Likewise children have no difficulty in understanding the abstraction dot, though dots come in various sizes and shapes and colours. But an invisible point is NOT such an abstraction: for one cannot point to a point. Nor can one infer the existence of invisible points from other phenomena the way one can infer the existence of electrons from tracks in a bubble chamber or infer fire from smoke. A geometric point, as taught in school today, is thus pure metaphysics; it has no real existence. People regrettably confound church metaphysics about unreal things with abstraction.

Further, a line too is asserted to be invisible by the NCERT 6th standard text. So I asked teachers and student how they can verify the postulate that exactly one straight line passes through any two points. They again had no answer. I also showed them that any two real dots can be connected by multiple straight-looking lines, so the postulate is not based on experience but solely on Western authority.

The church strategy of teaching about non-existent things forces students to abandon commonsense and rely on Western authority. Ultimately the only “reason” given by colonial education for why 1+1=2 is that some Western authority like Peano approved it! Those who resist this teaching, and try to understand on their own, are the one’s who find math difficult and abandon it.

But the text does not stop with one absurdity. After three years of allowing this nonsense about invisible points to sink in to the child’s mind, the NCERT class 9 text introduces a further piece of nonsense. It says that a point cannot also be defined in other words. (Ditto for line and plane.) It explains this as follows. If one says “A point is that which has no part” then one is obliged to define “part” and so on, leading to an infinite regress.

Such an infinite regress does NOT arise in the case of a dog or dot, for one can simply point to several instances of dots, terminating the regress. The cause of the infinite regress is the desire to preach the church dogma of avoiding the empirical. This motive is hidden, and never made clear by the NCERT text. Even the direct connection to church dogma is obscured by false stories of “Euclid”.

The matters of “Euclid” and the exclusion of the empirical are relatively simple. But if colonised minds have not understood even these simple tricks in two centuries, they are unlikely to ever understand the more complex tricks involved. The church would have permanently duped them through “education”. Thus, once students are conditioned to regard mathematics as pure metaphysics, a metaphysics of infinity crops up at every level: there an infinity of points in a line, an infinity of lines in a plane and so on. I reiterate that this metaphysics of infinity has nil practical value: a computer cannot handle any metaphysics of infinity, but most practical applications of math, such as sending a rocket to Mars, are accomplished using computers.

It is a common error to believe there is a unique notion of infinity, but I will not go into details here of how a particular metaphysics of infinity in math (especially calculus) forces us to accept church dogmas of eternity as part of science.10 Thus, the metaphysics which Europeans added to the Indian calculus forces time in physics to be like a line, as posited by core (post-Nicene) church dogma. This is the magic by which the metaphysics in math determines scientific “truth”. It is hard to explain this to people ignorant of math who are duped into thinking the belief in “laws of nature” is about science, though it is clearly a church dogma advanced by Aquinas in Summa Theologica.

We should change the teaching of math, and teach normal math solely for its practical value. Certainly we should do this at school level, for the benefit of the millions of students who drop out. They have no need to learn about the doctrine of invisible points and lines. The aim of colonial education was to teach people subordination to Western authority, but I dream of a new generation of children freed from the shackles which tie the colonised minds of many of our “educationists”.

But the tragedy is that the system cannot be changed. The students cannot change it. Even if the text is wrong, they are compelled to recite it under threat of failure. The teachers cannot change it, they must teach from the text or they risk losing their jobs. The government—ministers and bureaucrats—won’t risk changing it for they are ignorant and fear ridicule and loss of power if something goes wrong. The “experts” have a vested interest in it, so they will not change it. They refuse even to discuss things publicly.

There is an additional layer of protection which preserves myths and dogmas in math. This church method of censorship comes naturally to the colonised minds (intellectuals, journalists and so forth) who have been indoctrinated by the system. Unable to address an iota of the substantive critique, they will abuse, ridicule and reject and censor it. This censorship is done by loyal gatekeepers ignorant of both the philosophy of math and church theology. In this country of the blind, the two-eyed man is blinded because the colonially educated intelligentsia has been taught numerous subtle superstitions far more dangerous than astrology.

This is how the church controls mass behaviour—through mass superstitions—which it has smuggled into math and science to make those superstitions credible. Censorship defends that strategy. The only hope is that, today, people in the slums of Soweto understand what the colonised intellectuals elsewhere do not, that colonial education spreads superstitions packaged as part of math and science.

    Thought – provoking article on an interesting topic. As with history, the colonial notions of math must change and counter arguments to the established ones should be discussed

    1. Aditya Nigam

      @Lefty Technocrat, This is the best you could get, is it? Raju’s piece may have a lot of polemical charge, but he is making an important argument. You reply with hot air? In case you have an argument – responding to the points raised in the piece, do try and put it together. And yes, don’t forget to use your own name.

  2. Laxmi

    It’s really interesting to know more facts which are unknown and probably we wouldn’t have given a lot of importance to it
    Good one!¡

  3. Rama

    While it is an important argument and needs a lot more research and writing, as a social scientist I am deeply uncomfortable by the writer’s inclination to collapse complicated histories spanning several centuries and regions: Ancient Greece, Roman church, standardisation of education in Europe, British colonisation (which, let us not forget, does not follow the Catholic church). Many important arguments within postcolonial studies have been let down by the way evidence is presented. I am willing to be convinced but this article compresses histories and homogenises Europe in service of its argument.

    1. @Rama. A lot of research has already been done, as anyone with even a little research background would have immediately noticed. Two books and several articles are cited in the post itself. Rama has not gone through them, for he raises no specific objection to even a single sentence in my 500 page tome Cultural Foundations of Mathematics or my book Euclid and Jesus. Had he seen at least the censored article, he would have found it cites a longer list of my books and papers posted at http://ckraju.net/papers/Reading-list-Bengaluru.html.

      Does he contest my statements about Ptolemy in my booklet Is Science Western in Origin? Then there are my statements about Archimedes, also found in my recent lectures at the University of South Africa on “Not out of Greece”, posted at http://ckraju.net/unisa. Or my statement about Aristotle in my article on logic for the Springer encyclopedia? Then there are my numerous articles on decolonising education. Or is he challenging the physics which results from decolonized math? Say my theory of Lorentz covariant retarded gravitation which arises by debunking Newton’s and the formalist understanding of calculus and correcting the consequent error in Newtonian physics. BTW, the latest on that is at http://ckraju.net/papers/Flyby-experiment-article.pdf.

      Rama passes a sweeping judgment without being able to contest even one sentence, in the thousands of pages of research I have published, so Rama’s opinion has no value. It is exactly the attitude of the censors: we don’t know, we don’t need to know, we reject because it doesn’t fit our beliefs.

      Basically, he seems deeply uncomfortable that the grand myths of “Ancient Greece” with which he was indoctrinated have collapsed like a house of cards. He imagines they have more solidity. But, on my research, and as stated in the post, there is less than nil evidence for these myths. Hence, after a decade of attempts to debate my research, I offered a 2 lakh prize for serious (primary) evidence on Euclid. The prize is standing for seven years. Since Rama says I have not done adequate research he should quickly claim the prize. If he does not then his actions speak louder than his words.

      Think of it. Is it ethical to teach these lousy church/racist/colonial myths to gullible school children if no expert in the world can produce evidence for them?

      Rama makes a desperate attempt to suggest that Protestants were fundamentally different from Roman Catholics. But both are part of the Nicene creed, and both accept Augustine and also Aquinas’ theology of reason which came before the split. Both used education to breed missionaries. As for math, these myths were very much taught also in Protestant Britain; for example in Cambridge, where the norm was blind imitation of “Euclid” until 1887, after which some latitude was permitted, though not in “Euclid’s” definitions or common notions or the order of propositions. And there was no secular education in Britain until 1871, when it came only at the primary level, but “Euclid” continued to be taught for and in Cambridge.

      As for convincing the indoctrinated, I have long maintained that it is harder to convince the colonised mind of its superstitions than astrologers. My key concern is to prevent indoctrination of the next generation. So, debate if you can, but ONLY on specific issues, or write a counter article and I will respond appropriately.
