Why David Horowitz attacks academia

Regular readers of this blog know that David Horowitz has been behind efforts to introduce the so-called Academic Bill of Rights, allegedly to “protect” college students from academic bullying by their professors. He has been going around the country, speaking on college campuses and to state legislatures, trying to place limits on what professors can and cannot say. In the process, he has also attacked what he considers the laziness of the academic life.

Horowitz resorts to his usual over-the-top rhetoric. He accuses faculty as follows: “Shiftless, lazy good-for-nothings? Try the richly paid leftist professors securely ensconced in their irrelevant ivory towers” and again “You teach on average two courses and spend six hours a week in class. You work eight months out of the year and have four months paid vacation. And every seven years you get ten months paid vacation.”

Such utterances perpetuate a strong misunderstanding about the nature of a university and of what faculty do. People who say such things see it only as a place where the only worthwhile activities occur in the classroom, and even then, they see the process of teaching very narrowly, as that of transmitting information. Hence they are baffled that college professors seem to spend so little time in the classroom, and see the whole thing as some kind of boondoggle.

People who think like this overlook the fact that faculty are not hired just to transmit knowledge. They are also hired to create new knowledge. Indeed that is one of the key functions of all universities, but especially research universities. This requires faculty to learn, and to keep on learning all their lives, and this requires time more than anything else.

It is for this same reason (that learning takes time) that students can get a degree without spending more that 15 hours or so per week actually in class, along with long summer breaks. This enables them to think and read and discuss ideas. (This is why I am always concerned about those students at Case who have double- and triple-majors and throw in a couple of minors as well. I admire their ambition, energy, and work ethic but am concerned that in the process of accumulating credit hours, they don’t have time to reflect on their learning, to toy with new ideas, and hence are not learning deeply enough.) So the logical end point of Horowitz’s claim should be that college students too are not spending enough time in class and are also “shiftless, lazy good for nothings.”

Universities have been the source of much of the new knowledge that has revolutionized our world. And the reason that they have been able to do so is because its faculty have been given the time to generate new ideas and put them to use. In Bertholt Brecht’s play Life of Galileo Galileo himself complains to his university chancellor that he was teaching so much that he did not have time to learn.

My father worked in a bank all his life. On his desk he had an ‘in’ box and an ‘out’ box. He would pretty much spend each day reading and signing off on papers, transferring them from the in to the out, and then he would go home, his work for the day done. His work was well defined and a ‘hard day’s work’ meant that he had been kept busy all day.

A faculty member’s life does not have that same daily rhythm. Faculty members also have things that they need to do each day (prepare for class, teach, grade papers, attend meetings, write committee reports, talk with students and respond to their emails). But these things come in waves and they have other duties that cannot be done in a nine-to-five time frame (such as write a book or research paper, solve a problem, prepare research proposals, do research). These things are carried around in their minds all the time. The stereotype of the ‘absent-minded professor’ has a kernel of truth but it is not that the professor is actually forgetful. It is that he or she is always thinking about the ideas of their discipline, wrestling with them, sorting them out, and this process is so engrossing that it can often drive other concerns from their minds. When I am working on a book or article, I can assure you that it is almost a full-time, 24/7 preoccupation. I think about it as I am going to sleep and it is the first thing in my mind when I wake up.

The difference is that most academics do not see this as ‘work’, if by that we mean doing something at the expense of something else that we’d rather do. We tend to love our ‘work’. This is what we live for and enjoy.

And perhaps, as we shall see in a later posting, this is what Horowitz really finds offensive about academics.

The rise of Catholic objections to Copernican ideas

(For those following the Copernican postings in sequence, I made a mistake. Today’s posting should have appeared BEFORE the one that dealt with The role of Protestant opposition to Copernicus. Sorry about that!)

The last myth that I will address concerning the Copernican revolution is that it met immediate, widespread, and religious opposition from the Catholic Church. This took the form of releasing the full force of the Inquisition against his ideas, which resulted in Copernican Giordano Bruno being burned for advocating those ideas and Galileo being forced to recant his support for Copernicus’ sun-centered universe. This is the view, for example, expressed by Bertholt Brecht in his famous play Life of Galileo.

Having fun with telephone representatives

Once in a while, I look in on the site Jesus’ General which is a parody website that is hard to describe but is often hilarious. It was the most recent winner of the Koufax Award for Most Humorous Blog.

Recently, the General posted an item about a telephone conversation that someone named Eugene Mirman had with a representative who was trying to get him to switch to her Christian long-distance phone company. As part of her sales pitch to Mirman, the phone rep first made sure that Mirman was opposed to same-sex marriages and then proceeded to allege that rival phone companies AT&T, MCI, and Verizon were all involved in promoting hard-core pornography, child pornography, and homosexuality, thus making them unworthy of God-fearing people.

The reading level of this blog

I came across an interesting website recently. You type in the URL of any site and it comes back immediately with various measures of the site’s readability, including the years of education necessary to understand it, its clarity, and so forth. It also provides comparisons on these indices with various standard media such as newspapers and magazines.

So naturally the first thing that I did was put in this blog’s URL to see how I shaped up. Here is what I got:

Readability Results for http://blog.case.edu/mxs24
Average words per sentence 16.15
Words with 1 Syllable 3,230
Words with 2 Syllables 1,010
Words with 3 Syllables 561
Words with 4 or more Syllables 415
Percentage of word with three or more syllables 18.71%
Average Syllables per Word 1.65

That much was pretty straightforward. The other three numbers were more mysterious:
Gunning Fog Index 13.94
Flesch Reading Ease 51.07
Flesch-Kincaid Grade 10.15

The site helpfully explains that the Fog Index “is a rough measure of how many years of schooling it would take someone to understand the content. The lower the number, the more understandable the content will be to your visitors. Results over seventeen are reported as seventeen, where seventeen is considered post-graduate level.” Looking at the algorithm, it seems to depend entirely on the number of words per sentence and the percentage of words that have three or more syllables.

So it takes about 14 years of education (or up to college sophomore level) for someone to understand the content of my website. So clearly I am not going to get huge market share with my blog.

For comparison, some Fog Index Scores are given for other publications:

6 TV guides, The Bible, Mark Twain
8 Reader’s Digest
8 – 10 Most popular novels
10 Time, Newsweek
11 Wall Street Journal
14 The Times, The Guardian
15 – 20 Academic papers
Over 20 Only government sites can get away with this, because you can’t ignore them.
Over 30 The government is covering something up

Since my Fog Index score is close to 15, it seems like it is hard for me to shake the habits of writing in the style of academic papers even in the more casual setting of a blog.

The Flesch Reading Ease number “rates the text on a 100-point scale. The higher the score, the easier it is to understand the document. Authors are encouraged to aim for a score of approximately 60 to 70.” So I flunk this score pretty badly, it looks like. This algorithm, seems to depend entirely on the number of words per sentence and the average number of syllables per word.

The Flesch-Kincaid grade level, like the Gunning-Fog index, “is a rough measure of how many years of schooling it would take someone to understand the content. Negative results are reported as zero, and numbers over twelve are reported as twelve.” This seems like the same measure as the Fog Index, but uses average number of syllables per word instead on percentage of words with three syllables or more.

What is one to make of things like this? I find them fun even if I don’t take them too seriously. For one thing, you have to be skeptical of these instant computer-generated analyses of such complex things as writing. While these programs are great at doing numbers, one has to be wary of claims that they can accurately measure things like clarity and reading grade level. They all assume that the number of polysyllabic words and the length of sentences are the only factors, and that the nature of the content is immaterial.

This explains the results for the Bible, which had initially puzzled me. It is ranked together with TV Guide, although surely it is a more difficult book to understand. But it does use short words and sentences. This kind of algorithm also also might explain why the Wall Street Journal, which one might think is less readable than the New York Times, scores at three grades below it.

Suppose I want to become more easily readable. Should I use more words of one syllable? Or shorter sentences? Or both? Or is it the topics that cause the problem? When you write about academic topics, polysyllabic words (two already in this sentence!) creep in without any effort. Can I write about the Copernican Revolution (two more!) and avoid words like heliocentric (another one!)

To become more readable must I switch my focus from history and philosophy of science to Britney Spears? There are some prices that are too high to pay even for increased ease of readability…

The role of Protestant opposition to Copernicus

For many years after the publication of Copernicus’ book De Revolutionibus Orbium Caelestium in 1543, his ideas remained within the mathematical astronomy community. The more popular books on astronomy and cosmology either were unaware of his work or chose to ignore them. But there were a few non-astronomers such as poets who were aware of his work and they ridiculed it for advocating a moving Earth, not because of any ideas of heresy. It was though the poets and other popularizing writers of that time that Copernicus’ ideas became more widely known.

The myth concerning circular orbits

In this posting we will examine the myth that the Copernican revolution was hampered by its insistence that the orbits be circles.

To understand the reasons behind this we need to look at the work of an influential, but often unrecognized, player in the Copernican revolution, the astronomer Tycho Brahe (1546-1601). He is considered the greatest naked-eye astronomer. He lived just before the invention of telescopes and the accuracy, scope, and reliability of his observations had enormous impact on the field.

It is interesting that Brahe, like most astronomers at that time, rejected Copernicus’ ideas of a moving Earth. He could not accept the arguments for the Earth’s motion, seeing that as creating more problems than solving them. In fact, he developed his own system (called the Tychonic system) that was mathematically equivalent to the Copernican system, but had the Earth as a stationary center. (p. 202. Most of the material in this post is from Thomas Kuhn’s book The Copernican Revolution and page numbers are from that book.)

Copernicus’ ideas gain support from a few astronomers

As astronomical observations became more comprehensive, and as sea-faring became more widespread, the need for better star-charts in order to have more accurate time-keeping and navigation became imperative. In order to meet this demand for increased accuracy, the method of epicycles outlined by Ptolemy became more and more complicated, and was extended in different ways by different mathematical astronomers until it became hard to say what the Ptolemaic system was. Instead there were a whole set of different calculations all based on the Ptolemaic system, all getting increasingly complicated. And none of them quite agreed with the full range of good naked-eye observations. (p. 139. Most of the material in this post is from Thomas Kuhn’s book The Copernican Revolution and page numbers are from that book.) [Read more…]

Copernicus and the laws of physics

In a previous post, we saw that the popular notion that the Copernican model of the universe was opposed because it implied a demotion for human beings is not supported by close examination of the views of the people actually living in those times. It is, instead, a revisionist version of events that gained ascendancy around 1700 or so.

In today’s post we will examine the myth that the immediate opposition to Copernicus was raised by religious people. The fact that the Copernican model was not perceived contemporaneously as a demotion already weakens the case for that story but there’s more.

Was the Copernican model a demotion for human beings?

In this post, we will look at one particular myth surrounding the Copernican story, the one that says that Copernican ideas were opposed because they implied a demotion for human beings.

Nicolaus Copernicus (1473-1543) published De Revolutionibus Orbium Caelestium, his epic work describing a heliocentric system, in 1543 the year of his death. Until then, Ptolemy’s geocentric model described in his Almagest had been the one used for studying planetary motions. In this model, the Earth was at the center of the universe and every celestial body orbited about the center. The Almagest was the “first systematic mathematical treatise to give a complete, detailed, and quantitative account of all the celestial motions.” (Thomas Kuhn, The Copernican Revolution, p. 72) This work was so good and its methods so powerful, that it provided the framework for astronomical calculations for nearly 1500 years. It was the framework that guided Copernicus’ own work.

Looking closely at scientific history

Since I started looking more closely into the history of science, there are two things that I have learned that I have recast into principles.

The first is that the more closely we examine important historical events in science, the less resemblance they bear to the popular condensed capsule versions that are learned in school or college or portrayed in the popular media. The earlier posting about Columbus and the flat Earth is a case in point.

The second principle is that while science textbooks are usually good for teaching the current principles of science, they tend to be bad for teaching anything about the history of science or the nature of science. In those cases, what they usually describe is better described as folklore rather than history.

Take for example one of the most famous of all scientific revolutions, the one associated with Copernicus. The popular version of this story goes as follows:

The ancient Greeks, while pretty good at mapping the stars and motion of planets, tended to create models of the universe that were strongly influenced by religious, philosophical, and aesthetic considerations, rather than on observation and experiment. Hence they came up with the idea that the Earth was the stationary center of the universe (which pleased those religious people who wanted to give pride of place to the home of God’s greatest creation – human beings) and that the stars and planets were embedded on the surface of a sphere that rotated around the Earth in circles, which pleased those philosophers with highly refined sensibilities who felt that since the circle and sphere were the most perfect geometric shapes, they had to play a central role in the cosmos.
